+Description:
+                Each regulator directory will contain a field called
+                state. This holds the regulator output state.
+
+                This will be one of the following strings:

+                'enabled'
+                'disabled'
+                'unknown'
+
+                'enabled' means the regulator output is ON and is supplying
+                power to the system.
+
+                'disabled' means the regulator output is OFF and is not
+                supplying power to the system..
+
+                'unknown' means software cannot determine the state.
+
+                NOTE: this field can be used in conjunction with microvolts
+                and microamps to determine regulator output levels.

+Upgrading I2C Drivers to the new 2.6 Driver Model
+=================================================
+
+Ben Dooks <ben-linux@fluff.org>
+
+Introduction
+------------
+
+This guide outlines how to alter existing Linux 2.6 client drivers from
+the old to the new new binding methods.
+
+
+Example old-style driver
+------------------------
+
+
+struct example_state {
+        struct i2c_client       client;
+        ....
+};
+
+static struct i2c_driver example_driver;
+
+static unsigned short ignore[] = { I2C_CLIENT_END };
+static unsigned short normal_addr[] = { OUR_ADDR, I2C_CLIENT_END };
+
+I2C_CLIENT_INSMOD;
+
+static int example_attach(struct i2c_adapter *adap, int addr, int kind)
+{
+        struct example_state *state;
+        struct device *dev = &adap->dev;  /* to use for dev_ reports */
+        int ret;
+
+        state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
+        if (state == NULL) {
+                dev_err(dev, "failed to create our state\n");
+                return -ENOMEM;
+        }
+
+        example->client.addr    = addr;
+        example->client.flags   = 0;
+        example->client.adapter = adap;
+
+        i2c_set_clientdata(&state->i2c_client, state);
+        strlcpy(client->i2c_client.name, "example", I2C_NAME_SIZE);
+
+        ret = i2c_attach_client(&state->i2c_client);
+        if (ret < 0) {
+                dev_err(dev, "failed to attach client\n");
+                kfree(state);
+                return ret;
+        }
+
+        dev = &state->i2c_client.dev;
+
+        /* rest of the initialisation goes here. */
+
+        dev_info(dev, "example client created\n");
+
+        return 0;
+}
+
+static int __devexit example_detach(struct i2c_client *client)
+{
+        struct example_state *state = i2c_get_clientdata(client);
+
+        i2c_detach_client(client);
+        kfree(state);
+        return 0;
+}
+
+static int example_attach_adapter(struct i2c_adapter *adap)
+{
+        return i2c_probe(adap, &addr_data, example_attach);
+}
+
+static struct i2c_driver example_driver = {
+        .driver         = {
+                .owner          = THIS_MODULE,
+                .name           = "example",
+        },
+        .attach_adapter = example_attach_adapter,
+        .detach_client  = __devexit_p(example_detach),
+        .suspend        = example_suspend,
+        .resume         = example_resume,
+};
+
+
+Updating the client
+-------------------
+
+The new style binding model will check against a list of supported
+devices and their associated address supplied by the code registering
+the busses. This means that the driver .attach_adapter and
+.detach_adapter methods can be removed, along with the addr_data,
+as follows:
+
+- static struct i2c_driver example_driver;
+
+- static unsigned short ignore[] = { I2C_CLIENT_END };
+- static unsigned short normal_addr[] = { OUR_ADDR, I2C_CLIENT_END };
+
+- I2C_CLIENT_INSMOD;
+
+- static int example_attach_adapter(struct i2c_adapter *adap)
+- {
+-       return i2c_probe(adap, &addr_data, example_attach);
+- }
+
+ static struct i2c_driver example_driver = {
+-       .attach_adapter = example_attach_adapter,
+-       .detach_client  = __devexit_p(example_detach),
+ }
+
+Add the probe and remove methods to the i2c_driver, as so:
+
+ static struct i2c_driver example_driver = {
++       .probe          = example_probe,
++       .remove         = __devexit_p(example_remove),
+ }
+
+Change the example_attach method to accept the new parameters
+which include the i2c_client that it will be working with:
+
+- static int example_attach(struct i2c_adapter *adap, int addr, int kind)
++ static int example_probe(struct i2c_client *client,
++                          const struct i2c_device_id *id)
+
+Change the name of example_attach to example_probe to align it with the
+i2c_driver entry names. The rest of the probe routine will now need to be
+changed as the i2c_client has already been setup for use.
+
+The necessary client fields have already been setup before
+the probe function is called, so the following client setup
+can be removed:
+
+-       example->client.addr    = addr;
+-       example->client.flags   = 0;
+-       example->client.adapter = adap;
+-
+-       strlcpy(client->i2c_client.name, "example", I2C_NAME_SIZE);
+
+The i2c_set_clientdata is now:
+
+-       i2c_set_clientdata(&state->client, state);
++       i2c_set_clientdata(client, state);
+
+The call to i2c_attach_client is no longer needed, if the probe
+routine exits successfully, then the driver will be automatically
+attached by the core. Change the probe routine as so:
+
+-       ret = i2c_attach_client(&state->i2c_client);
+-       if (ret < 0) {
+-               dev_err(dev, "failed to attach client\n");
+-               kfree(state);
+-               return ret;
+-       }
+
+
+Remove the storage of 'struct i2c_client' from the 'struct example_state'
+as we are provided with the i2c_client in our example_probe. Instead we
+store a pointer to it for when it is needed.
+
+struct example_state {
+-       struct i2c_client       client;
++       struct i2c_client       *client;
+
+the new i2c client as so:
+
+-       struct device *dev = &adap->dev;  /* to use for dev_ reports */
++       struct device *dev = &i2c_client->dev;  /* to use for dev_ reports */
+
+And remove the change after our client is attached, as the driver no
+longer needs to register a new client structure with the core:
+
+-       dev = &state->i2c_client.dev;
+
+In the probe routine, ensure that the new state has the client stored
+in it:
+
+static int example_probe(struct i2c_client *i2c_client,
+                         const struct i2c_device_id *id)
+{
+        struct example_state *state;
+        struct device *dev = &i2c_client->dev;
+        int ret;
+
+        state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
+        if (state == NULL) {
+                dev_err(dev, "failed to create our state\n");
+                return -ENOMEM;
+        }
+
++       state->client = i2c_client;
+
+Update the detach method, by changing the name to _remove and
+to delete the i2c_detach_client call. It is possible that you
+can also remove the ret variable as it is not not needed for
+any of the core functions.
+
+- static int __devexit example_detach(struct i2c_client *client)
++ static int __devexit example_remove(struct i2c_client *client)
+{
+        struct example_state *state = i2c_get_clientdata(client);
+
+-       i2c_detach_client(client);
+
+And finally ensure that we have the correct ID table for the i2c-core
+and other utilities:
+
++ struct i2c_device_id example_idtable[] = {
++       { "example", 0 },
++       { }
++};
++
++MODULE_DEVICE_TABLE(i2c, example_idtable);
+
+static struct i2c_driver example_driver = {
+        .driver         = {
+                .owner          = THIS_MODULE,
+                .name           = "example",
+        },
++       .id_table       = example_ids,
+
+
+Our driver should now look like this:
+
+struct example_state {
+        struct i2c_client       *client;
+        ....
+};
+
+static int example_probe(struct i2c_client *client,
+                         const struct i2c_device_id *id)
+{
+        struct example_state *state;
+        struct device *dev = &client->dev;
+
+        state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
+        if (state == NULL) {
+                dev_err(dev, "failed to create our state\n");
+                return -ENOMEM;
+        }
+
+        state->client = client;
+        i2c_set_clientdata(client, state);
+
+        /* rest of the initialisation goes here. */
+
+        dev_info(dev, "example client created\n");
+
+        return 0;
+}
+
+static int __devexit example_remove(struct i2c_client *client)
+{
+        struct example_state *state = i2c_get_clientdata(client);
+
+        kfree(state);
+        return 0;
+}
+
+static struct i2c_device_id example_idtable[] = {
+        { "example", 0 },
+        { }
+};
+
+MODULE_DEVICE_TABLE(i2c, example_idtable);
+
+static struct i2c_driver example_driver = {
+        .driver         = {
+                .owner          = THIS_MODULE,
+                .name           = "example",
+        },
+        .id_table       = example_idtable,
+        .probe          = example_probe,

+Regulator Consumer Driver Interface
+===================================
+
+This text describes the regulator interface for consumer device drivers.
+Please see overview.txt for a description of the terms used in this text.
+
+
+1. Consumer Regulator Access (static & dynamic drivers)
+=======================================================
+
+A consumer driver can get access to it's supply regulator by calling :-
+
+regulator = regulator_get(dev, "Vcc");
+
+The consumer passes in it's struct device pointer and power supply ID. The core
+then finds the correct regulator by consulting a machine specific lookup table.
+If the lookup is successful then this call will return a pointer to the struct
+regulator that supplies this consumer.
+
+To release the regulator the consumer driver should call :-
+
+regulator_put(regulator);
+
+Consumers can be supplied by more than one regulator e.g. codec consumer with
+analog and digital supplies :-
+
+digital = regulator_get(dev, "Vcc");  /* digital core */
+analog = regulator_get(dev, "Avdd");  /* analog */
+
+The regulator access functions regulator_get() and regulator_put() will
+usually be called in your device drivers probe() and remove() respectively.
+
+
+2. Regulator Output Enable & Disable (static & dynamic drivers)
+====================================================================
+
+A consumer can enable it's power supply by calling:-
+
+int regulator_enable(regulator);
+
+NOTE: The supply may already be enabled before regulator_enabled() is called.
+This may happen if the consumer shares the regulator or the regulator has been
+previously enabled by bootloader or kernel board initialization code.
+
+A consumer can determine if a regulator is enabled by calling :-
+
+int regulator_is_enabled(regulator);
+
+This will return > zero when the regulator is enabled.
+
+
+A consumer can disable it's supply when no longer needed by calling :-
+
+int regulator_disable(regulator);
+
+NOTE: This may not disable the supply if it's shared with other consumers. The
+regulator will only be disabled when the enabled reference count is zero.
+
+Finally, a regulator can be forcefully disabled in the case of an emergency :-
+
+int regulator_force_disable(regulator);
+
+NOTE: this will immediately and forcefully shutdown the regulator output. All
+consumers will be powered off.
+
+
+3. Regulator Voltage Control & Status (dynamic drivers)
+======================================================
+
+Some consumer drivers need to be able to dynamically change their supply
+voltage to match system operating points. e.g. CPUfreq drivers can scale
+voltage along with frequency to save power, SD drivers may need to select the
+correct card voltage, etc.
+
+Consumers can control their supply voltage by calling :-
+
+int regulator_set_voltage(regulator, min_uV, max_uV);
+
+Where min_uV and max_uV are the minimum and maximum acceptable voltages in
+microvolts.
+
+NOTE: this can be called when the regulator is enabled or disabled. If called
+when enabled, then the voltage changes instantly, otherwise the voltage
+configuration changes and the voltage is physically set when the regulator is
+next enabled.
+
+The regulators configured voltage output can be found by calling :-
+
+int regulator_get_voltage(regulator);
+
+NOTE: get_voltage() will return the configured output voltage whether the
+regulator is enabled or disabled and should NOT be used to determine regulator
+output state. However this can be used in conjunction with is_enabled() to
+determine the regulator physical output voltage.
+
+
+4. Regulator Current Limit Control & Status (dynamic drivers)
+===========================================================
+
+Some consumer drivers need to be able to dynamically change their supply
+current limit to match system operating points. e.g. LCD backlight driver can
+change the current limit to vary the backlight brightness, USB drivers may want
+to set the limit to 500mA when supplying power.
+
+Consumers can control their supply current limit by calling :-
+
+int regulator_set_current_limit(regulator, min_uV, max_uV);
+
+Where min_uA and max_uA are the minimum and maximum acceptable current limit in
+microamps.
+
+NOTE: this can be called when the regulator is enabled or disabled. If called
+when enabled, then the current limit changes instantly, otherwise the current
+limit configuration changes and the current limit is physically set when the
+regulator is next enabled.
+
+A regulators current limit can be found by calling :-
+
+int regulator_get_current_limit(regulator);
+
+NOTE: get_current_limit() will return the current limit whether the regulator
+is enabled or disabled and should not be used to determine regulator current
+load.
+
+
+5. Regulator Operating Mode Control & Status (dynamic drivers)
+=============================================================
+
+Some consumers can further save system power by changing the operating mode of
+their supply regulator to be more efficient when the consumers operating state
+changes. e.g. consumer driver is idle and subsequently draws less current
+
+Regulator operating mode can be changed indirectly or directly.
+
+Indirect operating mode control.
+--------------------------------
+Consumer drivers can request a change in their supply regulator operating mode
+by calling :-
+
+int regulator_set_optimum_mode(struct regulator *regulator, int load_uA);
+
+This will cause the core to recalculate the total load on the regulator (based
+on all it's consumers) and change operating mode (if necessary and permitted)
+to best match the current operating load.
+
+The load_uA value can be determined from the consumers datasheet. e.g.most
+datasheets have tables showing the max current consumed in certain situations.
+
+Most consumers will use indirect operating mode control since they have no
+knowledge of the regulator or whether the regulator is shared with other
+consumers.
+
+Direct operating mode control.
+------------------------------
+Bespoke or tightly coupled drivers may want to directly control regulator
+operating mode depending on their operating point. This can be achieved by
+calling :-
+
+int regulator_set_mode(struct regulator *regulator, unsigned int mode);
+unsigned int regulator_get_mode(struct regulator *regulator);
+
+Direct mode will only be used by consumers that *know* about the regulator and
+are not sharing the regulator with other consumers.
+
+
+6. Regulator Events
+===================
+Regulators can notify consumers of external events. Events could be received by
+consumers under regulator stress or failure conditions.
+
+Consumers can register interest in regulator events by calling :-
+
+int regulator_register_notifier(struct regulator *regulator,
+                              struct notifier_block *nb);
+
+Consumers can uregister interest by calling :-
+
+int regulator_unregister_notifier(struct regulator *regulator,
+                                struct notifier_block *nb);
+
+Regulators use the kernel notifier framework to send event to thier interested
+consumers.

+Regulator Machine Driver Interface
+===================================
+
+The regulator machine driver interface is intended for board/machine specific
+initialisation code to configure the regulator subsystem. Typical things that
+machine drivers would do are :-
+
+ 1. Regulator -> Device mapping.
+ 2. Regulator supply configuration.
+ 3. Power Domain constraint setting.
+
+
+
+1. Regulator -> device mapping
+==============================
+Consider the following machine :-
+
+  Regulator-1 -+-> Regulator-2 --> [Consumer A @ 1.8 - 2.0V]
+               |
+               +-> [Consumer B @ 3.3V]
+
+The drivers for consumers A & B must be mapped to the correct regulator in
+order to control their power supply. This mapping can be achieved in machine
+initialisation code by calling :-
+
+int regulator_set_device_supply(const char *regulator, struct device *dev,
+                                const char *supply);
+
+and is shown with the following code :-
+
+regulator_set_device_supply("Regulator-1", devB, "Vcc");
+regulator_set_device_supply("Regulator-2", devA, "Vcc");
+
+This maps Regulator-1 to the 'Vcc' supply for Consumer B and maps Regulator-2
+to the 'Vcc' supply for Consumer A.
+
+
+2. Regulator supply configuration.
+==================================
+Consider the following machine (again) :-
+
+  Regulator-1 -+-> Regulator-2 --> [Consumer A @ 1.8 - 2.0V]
+               |
+               +-> [Consumer B @ 3.3V]
+
+Regulator-1 supplies power to Regulator-2. This relationship must be registered
+with the core so that Regulator-1 is also enabled when Consumer A enables it's
+supply (Regulator-2).
+
+This relationship can be register with the core via :-
+
+int regulator_set_supply(const char *regulator, const char *regulator_supply);
+
+In this example we would use the following code :-
+
+regulator_set_supply("Regulator-2", "Regulator-1");
+
+Relationships can be queried by calling :-
+
+const char *regulator_get_supply(const char *regulator);
+
+
+3. Power Domain constraint setting.
+===================================
+Each power domain within a system has physical constraints on voltage and
+current. This must be defined in software so that the power domain is always
+operated within specifications.
+
+Consider the following machine (again) :-
+
+  Regulator-1 -+-> Regulator-2 --> [Consumer A @ 1.8 - 2.0V]
+               |
+               +-> [Consumer B @ 3.3V]
+
+This gives us two regulators and two power domains:
+
+                   Domain 1: Regulator-2, Consumer B.
+                   Domain 2: Consumer A.
+
+Constraints can be registered by calling :-
+
+int regulator_set_platform_constraints(const char *regulator,
+        struct regulation_constraints *constraints);
+
+The example is defined as follows :-
+
+struct regulation_constraints domain_1 = {
+        .min_uV = 3300000,
+        .max_uV = 3300000,
+        .valid_modes_mask = REGULATOR_MODE_NORMAL,
+};
+
+struct regulation_constraints domain_2 = {
+        .min_uV = 1800000,
+        .max_uV = 2000000,
+        .valid_ops_mask = REGULATOR_CHANGE_VOLTAGE,
+        .valid_modes_mask = REGULATOR_MODE_NORMAL,
+};
+
+regulator_set_platform_constraints("Regulator-1", &domain_1);
+regulator_set_platform_constraints("Regulator-2", &domain_2);

+Linux voltage and current regulator framework
+=============================================
+
+About
+=====
+
+This framework is designed to provide a standard kernel interface to control
+voltage and current regulators.
+
+The intention is to allow systems to dynamically control regulator power output
+in order to save power and prolong battery life. This applies to both voltage
+regulators (where voltage output is controllable) and current sinks (where
+current limit is controllable).

+
+Nomenclature
+============
+
+Some terms used in this document:-
+
+  o Regulator    - Electronic device that supplies power to other devices.
+                   Most regulators can enable and disable their output whilst
+                   some can control their output voltage and or current.
+
+                   Input Voltage -> Regulator -> Output Voltage
+
+
+  o PMIC         - Power Management IC. An IC that contains numerous regulators
+                   and often contains other susbsystems.
+
+
+  o Consumer     - Electronic device that is supplied power by a regulator.
+                   Consumers can be classified into two types:-
+
+                   Static: consumer does not change it's supply voltage or
+                   current limit. It only needs to enable or disable it's
+                   power supply. It's supply voltage is set by the hardware,
+                   bootloader, firmware or kernel board initialisation code.
+
+                   Dynamic: consumer needs to change it's supply voltage or
+                   current limit to meet operation demands.
+
+
+  o Power Domain - Electronic circuit that is supplied it's input power by the
+                   output power of a regulator, switch or by another power
+                   domain.
+
+                   The supply regulator may be behind a switch(s). i.e.
+
+                   Regulator -+-> Switch-1 -+-> Switch-2 --> [Consumer A]
+                              |             |
+                              |             +-> [Consumer B], [Consumer C]
+                              |
+                              +-> [Consumer D], [Consumer E]
+
+                   That is one regulator and three power domains:
+
+                   Domain 1: Switch-1, Consumers D & E.
+                   Domain 2: Switch-2, Consumers B & C.
+                   Domain 3: Consumer A.
+
+                   and this represents a "supplies" relationship:
+
+                   Domain-1 --> Domain-2 --> Domain-3.
+
+                   A power domain may have regulators that are supplied power
+                   by other regulators. i.e.
+
+                   Regulator-1 -+-> Regulator-2 -+-> [Consumer A]
+                                |
+                                +-> [Consumer B]
+
+                   This gives us two regulators and two power domains:
+
+                   Domain 1: Regulator-2, Consumer B.
+                   Domain 2: Consumer A.
+
+                   and a "supplies" relationship:
+
+                   Domain-1 --> Domain-2
+
+
+  o Constraints  - Constraints are used to define power levels for performance
+                   and hardware protection. Constraints exist at three levels:
+
+                   Regulator Level: This is defined by the regulator hardware
+                   operating parameters and is specified in the regulator
+                   datasheet. i.e.
+
+                     - voltage output is in the range 800mV -> 3500mV.
+                     - regulator current output limit is 20mA @ 5V but is
+                       10mA @ 10V.
+
+                   Power Domain Level: This is defined in software by kernel
+                   level board initialisation code. It is used to constrain a
+                   power domain to a particular power range. i.e.
+
+                     - Domain-1 voltage is 3300mV
+                     - Domain-2 voltage is 1400mV -> 1600mV
+                     - Domain-3 current limit is 0mA -> 20mA.
+
+                   Consumer Level: This is defined by consumer drivers
+                   dynamically setting voltage or current limit levels.
+
+                   e.g. a consumer backlight driver asks for a current increase
+                   from 5mA to 10mA to increase LCD illumination. This passes
+                   to through the levels as follows :-
+
+                   Consumer: need to increase LCD brightness. Lookup and
+                   request next current mA value in brightness table (the
+                   consumer driver could be used on several different
+                   personalities based upon the same reference device).
+
+                   Power Domain: is the new current limit within the domain
+                   operating limits for this domain and system state (e.g.
+                   battery power, USB power)
+
+                   Regulator Domains: is the new current limit within the
+                   regulator operating parameters for input/ouput voltage.
+
+                   If the regulator request passes all the constraint tests
+                   then the new regulator value is applied.
+
+
+Design
+======
+
+The framework is designed and targeted at SoC based devices but may also be
+relevant to non SoC devices and is split into the following four interfaces:-
+
+
+   1. Consumer driver interface.
+
+      This uses a similar API to the kernel clock interface in that consumer
+      drivers can get and put a regulator (like they can with clocks atm) and
+      get/set voltage, current limit, mode, enable and disable. This should
+      allow consumers complete control over their supply voltage and current
+      limit. This also compiles out if not in use so drivers can be reused in
+      systems with no regulator based power control.
+
+        See Documentation/power/regulator/consumer.txt
+
+   2. Regulator driver interface.
+
+      This allows regulator drivers to register their regulators and provide
+      operations to the core. It also has a notifier call chain for propagating
+      regulator events to clients.
+
+        See Documentation/power/regulator/regulator.txt
+
+   3. Machine interface.
+
+      This interface is for machine specific code and allows the creation of
+      voltage/current domains (with constraints) for each regulator. It can
+      provide regulator constraints that will prevent device damage through
+      overvoltage or over current caused by buggy client drivers. It also
+      allows the creation of a regulator tree whereby some regulators are
+      supplied by others (similar to a clock tree).
+
+        See Documentation/power/regulator/machine.txt
+
+   4. Userspace ABI.
+
+      The framework also exports a lot of useful voltage/current/opmode data to
+      userspace via sysfs. This could be used to help monitor device power
+      consumption and status.
+
+        See Documentation/ABI/testing/regulator-sysfs.txt

+Regulator Driver Interface
+==========================
+
+The regulator driver interface is relatively simple and designed to allow
+regulator drivers to register their services with the core framework.
+
+
+Registration
+============
+
+Drivers can register a regulator by calling :-
+
+struct regulator_dev *regulator_register(struct regulator_desc *regulator_desc,
+                                          void *reg_data);
+
+This will register the regulators capabilities and operations the regulator
+core. The core does not touch reg_data (private to regulator driver).
+
+Regulators can be unregistered by calling :-
+
+void regulator_unregister(struct regulator_dev *rdev);
+
+
+Regulator Events
+================
+Regulators can send events (e.g. over temp, under voltage, etc) to consumer
+drivers by calling :-
+
+int regulator_notifier_call_chain(struct regulator_dev *rdev,
+                                  unsigned long event, void *data);

-        Initial conditions:
-        -------------------
-        
-        Tasks that need to be perform by the boot ROM before control is
-        transferred to zImage (compressed Linux kernel):
-
-        - Define the IMMR to 0xf0000000
-
-        - Initialize the memory controller so that RAM is available at
-          physical address 0x00000000.  On the SBC8260 is this 16M (64M)
-          SDRAM.
-
-        - The boot ROM should only clear the RAM that it is using.
-
-          The reason for doing this is to enhances the chances of a
-          successful post mortem on a Linux panic.  One of the first
-          items to examine is the 16k (LOG_BUF_LEN) circular console
-          buffer called log_buf which is defined in kernel/printk.c.
-
-        - To enhance boot ROM performance, the I-cache can be enabled.

-
-          LiMon (LInux MONitor) runs with and starts Linux with MMU
-          off, I-cache enabled, D-cache disabled.  The I-cache doesn't
-          need hints from the MMU to work correctly as the D-cache
-          does.  No D-cache means no special code to handle devices in
-          the presence of cache (no snooping, etc). The use of the
-          I-cache means that the monitor can run acceptably fast
-          directly from ROM, rather than having to copy it to RAM.
-
-        - Build the board information structure (see 
-          include/asm-ppc/est8260.h for its definition)
-
-        - The compressed Linux kernel (zImage) contains a bootstrap loader 
-          that is position independent; you can load it into any RAM, 
-          ROM or FLASH memory address >= 0x00500000 (above 5 MB), or
-          at its link address of 0x00400000 (4 MB).
-
-          Note: If zImage is loaded at its link address of 0x00400000 (4 MB),
-                then zImage will skip the step of moving itself to 
-                its link address.
-
-        - Load R3 with the address of the board information structure
-
-        - Transfer control to zImage
-
-        - The Linux console port is SMC1, and the baud rate is controlled
-          from the bi_baudrate field of the board information structure.
-          On thing to keep in mind when picking the baud rate, is that
-          there is no flow control on the SMC ports.  I would stick
-          with something safe and standard like 19200.
-
-          On the EST SBC8260, the SMC1 port is on the COM1 connector of
-          the board.

-
-        Notes:
-        ------
-
-        - The chip selects can map 32K blocks and up (powers of 2)
-
-        - The SDRAM machine can handled up to 128Mbytes per chip select
-
-        - Linux uses the 60x bus memory (the SDRAM DIMM) for the 
-          communications buffers.
-
-        - BATs can map 128K-256Mbytes each.  There are four data BATs and
-          four instruction BATs.  Generally the data and instruction BATs
-          are mapped the same.
-
-        - The IMMR must be set above the kernel virtual memory addresses,
-          which start at 0xC0000000.  Otherwise, the kernel may crash as
-          soon as you start any threads or processes due to VM collisions 
-          in the kernel or user process space.
-
-
-          Details from Dan Malek <dan_malek@mvista.com> on 10/29/1999:
-
-          The user application virtual space consumes the first 2 Gbytes
-          (0x00000000 to 0x7FFFFFFF).  The kernel virtual text starts at
-          0xC0000000, with data following.  There is a "protection hole"
-          between the end of kernel data and the start of the kernel
-          dynamically allocated space, but this space is still within
-          0xCxxxxxxx.
-
-          Obviously the kernel can't map any physical addresses 1:1 in
-          these ranges.
-
-
-          Details from Dan Malek <dan_malek@mvista.com> on 5/19/2000:
-
-          During the early kernel initialization, the kernel virtual
-          memory allocator is not operational.  Prior to this KVM
-          initialization, we choose to map virtual to physical addresses
-          1:1.  That is, the kernel virtual address exactly matches the
-          physical address on the bus.  These mappings are typically done
-          in arch/ppc/kernel/head.S, or arch/ppc/mm/init.c.  Only
-          absolutely necessary mappings should be done at this time, for
-          example board control registers or a serial uart.  Normal device
-          driver initialization should map resources later when necessary.
-
-          Although platform dependent, and certainly the case for embedded
-          8xx, traditionally memory is mapped at physical address zero,
-          and I/O devices above physical address 0x80000000.  The lowest
-          and highest (above 0xf0000000) I/O addresses are traditionally 
-          used for devices or registers we need to map during kernel 
-          initialization and prior to KVM operation.  For this reason, 
-          and since it followed prior PowerPC platform examples, I chose 
-          to map the embedded 8xx kernel to the 0xc0000000 virtual address.
-          This way, we can enable the MMU to map the kernel for proper 
-          operation, and still map a few windows before the KVM is operational.
-
-          On some systems, you could possibly run the kernel at the 
-          0x80000000 or any other virtual address.  It just depends upon 
-          mapping that must be done prior to KVM operational.  You can never 
-          map devices or kernel spaces that overlap with the user virtual 
-          space.  This is why default IMMR mapping used by most BDM tools 
-          won't work.  They put the IMMR at something like 0x10000000 or 
-          0x02000000 for example.  You simply can't map these addresses early
-          in the kernel, and continue proper system operation.
-
-          The embedded 8xx/82xx kernel is mature enough that all you should 
-          need to do is map the IMMR someplace at or above 0xf0000000 and it 
-          should boot far enough to get serial console messages and KGDB 
-          connected on any platform.  There are lots of other subtle memory 
-          management design features that you simply don't need to worry 
-          about.  If you are changing functions related to MMU initialization,
-          you are likely breaking things that are known to work and are 
-          heading down a path of disaster and frustration.  Your changes 
-          should be to make the flexibility of the processor fit Linux, 
-          not force arbitrary and non-workable memory mappings into Linux.
-
-        - You don't want to change KERNELLOAD or KERNELBASE, otherwise the
-          virtual memory and MMU code will get confused.

- *  To enable debugger support, two things need to happen.  One, a
- *  call to set_debug_traps() is necessary in order to allow any breakpoints
- *  or error conditions to be properly intercepted and reported to gdb.
- *  Two, a breakpoint needs to be generated to begin communication.  This
- *  is most easily accomplished by a call to breakpoint().  Breakpoint()
- *  simulates a breakpoint by executing a BREAK instruction.
- *
- *
- *    The following gdb commands are supported:
- *
- * command          function                               Return value
- *
- *    g             return the value of the CPU registers  hex data or ENN
- *    G             set the value of the CPU registers     OK or ENN
- *
- *    mAA..AA,LLLL  Read LLLL bytes at address AA..AA      hex data or ENN
- *    MAA..AA,LLLL: Write LLLL bytes at address AA.AA      OK or ENN
- *
- *    c             Resume at current address              SNN   ( signal NN)
- *    cAA..AA       Continue at address AA..AA             SNN
- *
- *    s             Step one instruction                   SNN
- *    sAA..AA       Step one instruction from AA..AA       SNN
- *
- *    k             kill
- *
- *    ?             What was the last sigval ?             SNN   (signal NN)
- *
- *    bBB..BB       Set baud rate to BB..BB                OK or BNN, then sets
- *                                                         baud rate
- *
- * All commands and responses are sent with a packet which includes a
- * checksum.  A packet consists of
- *
- * $<packet info>#<checksum>.
- *
- * where
- * <packet info> :: <characters representing the command or response>
- * <checksum>    :: < two hex digits computed as modulo 256 sum of <packetinfo>>
- *
- * When a packet is received, it is first acknowledged with either '+' or '-'.
- * '+' indicates a successful transfer.  '-' indicates a failed transfer.
- *
- * Example:
- *
- * Host:                  Reply:
- * $m0,10#2a               +$00010203040506070809101112131415#42
- *
- *
- *  ==============
- *  MORE EXAMPLES:
- *  ==============
- *
- *  For reference -- the following are the steps that one
- *  company took (RidgeRun Inc) to get remote gdb debugging
- *  going. In this scenario the host machine was a PC and the
- *  target platform was a Galileo EVB64120A MIPS evaluation
- *  board.
- *
- *  Step 1:
- *  First download gdb-5.0.tar.gz from the internet.
- *  and then build/install the package.
- *
- *  Example:
- *    $ tar zxf gdb-5.0.tar.gz
- *    $ cd gdb-5.0
- *    $ ./configure --target=mips-linux-elf
- *    $ make
- *    $ install
- *    $ which mips-linux-elf-gdb
- *    /usr/local/bin/mips-linux-elf-gdb
- *
- *  Step 2:
- *  Configure linux for remote debugging and build it.
- *
- *  Example:
- *    $ cd ~/linux
- *    $ make menuconfig <go to "Kernel Hacking" and turn on remote debugging>
- *    $ make
- *
- *  Step 3:
- *  Download the kernel to the remote target and start
- *  the kernel running. It will promptly halt and wait
- *  for the host gdb session to connect. It does this
- *  since the "Kernel Hacking" option has defined
- *  CONFIG_KGDB which in turn enables your calls
- *  to:
- *     set_debug_traps();
- *     breakpoint();
- *
- *  Step 4:
- *  Start the gdb session on the host.
- *
- *  Example:
- *    $ mips-linux-elf-gdb vmlinux
- *    (gdb) set remotebaud 115200
- *    (gdb) target remote /dev/ttyS1
- *    ...at this point you are connected to
- *       the remote target and can use gdb
- *       in the normal fasion. Setting
- *       breakpoints, single stepping,
- *       printing variables, etc.

-          If you say yes here you get support for National Semiconductor LM75
-          sensor chips and clones: Dallas Semiconductor DS75 and DS1775 (in
-          9-bit precision mode), and TelCom (now Microchip) TCN75.
-
-          The DS75 and DS1775 in 10- to 12-bit precision modes will require
-          a force module parameter. The driver will not handle the extra
-          precision anyhow.
+          If you say yes here you get support for one common type of
+          temperature sensor chip, with models including:
+
+                - Dallas Semiconductor DS75 and DS1775
+                - Maxim MAX6625 and MAX6626
+                - Microchip MCP980x
+                - National Semiconductor LM75
+                - NXP's LM75A
+                - ST Microelectronics STDS75
+                - TelCom (now Microchip) TCN75
+                - Texas Instruments TMP100, TMP101, TMP75, TMP175, TMP275
+
+          This driver supports driver model based binding through board
+          specific I2C device tables.
+
+          It also supports the "legacy" style of driver binding.  To use
+          that with some chips which don't replicate LM75 quirks exactly,
+          you may need the "force" module parameter.
 
           This driver can also be built as a module.  If so, the module
           will be called lm75.

+ * GRU Chiplet:
+ *   The GRU is a user addressible memory accelerator. It provides
+ *   several forms of load, store, memset, bcopy instructions. In addition, it
+ *   contains special instructions for AMOs, sending messages to message
+ *   queues, etc.
+ *
+ *   The GRU is an integral part of the node controller. It connects
+ *   directly to the cpu socket. In its current implementation, there are 2
+ *   GRU chiplets in the node controller on each blade (~node).
+ *
+ *   The entire GRU memory space is fully coherent and cacheable by the cpus.
+ *
+ *   Each GRU chiplet has a physical memory map that looks like the following:

+ *      +-----------------+
+ *
+ *   Each of the "contexts" is a chunk of memory that can be mmaped into user
+ *   space. The context consists of 2 parts:
+ *
+ *      - an instruction space that can be directly accessed by the user
+ *        to issue GRU instructions and to check instruction status.
+ *
+ *      - a data area that acts as normal RAM.
+ *
+ *   User instructions contain virtual addresses of data to be accessed by the
+ *   GRU. The GRU contains a TLB that is used to convert these user virtual
+ *   addresses to physical addresses.
+ *
+ *   The "system control" area of the GRU chiplet is used by the kernel driver
+ *   to manage user contexts and to perform functions such as TLB dropin and
+ *   purging.
+ *
+ *   One context may be reserved for the kernel and used for cross-partition
+ *   communication. The GRU will also be used to asynchronously zero out
+ *   large blocks of memory (not currently implemented).
+ *
+ *
+ * Tables:
+ *
+ *      VDATA-VMA Data          - Holds a few parameters. Head of linked list of
+ *                                GTS tables for threads using the GSEG
+ *      GTS - Gru Thread State  - contains info for managing a GSEG context. A
+ *                                GTS is allocated for each thread accessing a
+ *                                GSEG.
+ *      GTD - GRU Thread Data   - contains shadow copy of GRU data when GSEG is
+ *                                not loaded into a GRU
+ *      GMS - GRU Memory Struct - Used to manage TLB shootdowns. Tracks GRUs
+ *                                where a GSEG has been loaded. Similar to
+ *                                an mm_struct but for GRU.
+ *
+ *      GS  - GRU State         - Used to manage the state of a GRU chiplet
+ *      BS  - Blade State       - Used to manage state of all GRU chiplets
+ *                                on a blade
+ *
+ *
+ *  Normal task tables for task using GRU.
+ *              - 2 threads in process
+ *              - 2 GSEGs open in process
+ *              - GSEG1 is being used by both threads
+ *              - GSEG2 is used only by thread 2

+ * gru_flush_tlb_range
+ *
+ * General purpose TLB invalidation function. This function scans every GRU in
+ * the ENTIRE system (partition) looking for GRUs where the specified MM has
+ * been accessed by the GRU. For each GRU found, the TLB must be invalidated OR
+ * the ASID invalidated. Invalidating an ASID causes a new ASID to be assigned
+ * on the next fault. This effectively flushes the ENTIRE TLB for the MM at the
+ * cost of (possibly) a large number of future TLBmisses.
+ *
+ * The current algorithm is optimized based on the following (somewhat true)
+ * assumptions:
+ *      - GRU contexts are not loaded into a GRU unless a reference is made to
+ *        the data segment or control block (this is true, not an assumption).
+ *        If a DS/CB is referenced, the user will also issue instructions that
+ *        cause TLBmisses. It is not necessary to optimize for the case where
+ *        contexts are loaded but no instructions cause TLB misses. (I know
+ *        this will happen but I'm not optimizing for it).
+ *      - GRU instructions to invalidate TLB entries are SLOOOOWWW - normally
+ *        a few usec but in unusual cases, it could be longer. Avoid if
+ *        possible.
+ *      - intrablade process migration between cpus is not frequent but is
+ *        common.
+ *      - a GRU context is not typically migrated to a different GRU on the
+ *        blade because of intrablade migration
+ *      - interblade migration is rare. Processes migrate their GRU context to
+ *        the new blade.
+ *      - if interblade migration occurs, migration back to the original blade
+ *        is very very rare (ie., no optimization for this case)
+ *      - most GRU instruction operate on a subset of the user REGIONS. Code
+ *        & shared library regions are not likely targets of GRU instructions.
+ *
+ * To help improve the efficiency of TLB invalidation, the GMS data
+ * structure is maintained for EACH address space (MM struct). The GMS is
+ * also the structure that contains the pointer to the mmu callout
+ * functions. This structure is linked to the mm_struct for the address space
+ * using the mmu "register" function. The mmu interfaces are used to
+ * provide the callbacks for TLB invalidation. The GMS contains:
+ *
+ *      - asid[maxgrus] array. ASIDs are assigned to a GRU when a context is
+ *        loaded into the GRU.
+ *      - asidmap[maxgrus]. bitmap to make it easier to find non-zero asids in
+ *        the above array
+ *      - ctxbitmap[maxgrus]. Indicates the contexts that are currently active
+ *        in the GRU for the address space. This bitmap must be passed to the
+ *        GRU to do an invalidate.
+ *
+ * The current algorithm for invalidating TLBs is:
+ *      - scan the asidmap for GRUs where the context has been loaded, ie,
+ *        asid is non-zero.
+ *      - for each gru found:
+ *              - if the ctxtmap is non-zero, there are active contexts in the
+ *                GRU. TLB invalidate instructions must be issued to the GRU.
+ *              - if the ctxtmap is zero, no context is active. Set the ASID to
+ *                zero to force a full TLB invalidation. This is fast but will
+ *                cause a lot of TLB misses if the context is reloaded onto the
+ *                GRU

+          Generic Voltage and Current Regulator support.
+
+          This framework is designed to provide a generic interface to voltage
+          and current regulators within the Linux kernel. It's intended to
+          provide voltage and current control to client or consumer drivers and
+          also provide status information to user space applications through a
+          sysfs interface.
+
+          The intention is to allow systems to dynamically control regulator
+          output in order to save power and prolong battery life. This applies
+          to both voltage regulators (where voltage output is controllable) and
+          current sinks (where current output is controllable).
+
+          This framework safely compiles out if not selected so that client
+          drivers can still be used in systems with no software controllable
+          regulators.
+
+          If unsure, say no.

+ * Regulator operating modes.
+ *
+ * Regulators can run in a variety of different operating modes depending on
+ * output load. This allows further system power savings by selecting the
+ * best (and most efficient) regulator mode for a desired load.
+ *
+ * Most drivers will only care about NORMAL. The modes below are generic and
+ * will probably not match the naming convention of your regulator data sheet
+ * but should match the use cases in the datasheet.
+ *
+ * In order of power efficiency (least efficient at top).
+ *
+ *  Mode       Description
+ *  FAST       Regulator can handle fast changes in it's load.
+ *             e.g. useful in CPU voltage & frequency scaling where
+ *             load can quickly increase with CPU frequency increases.
+ *
+ *  NORMAL     Normal regulator power supply mode. Most drivers will
+ *             use this mode.
+ *
+ *  IDLE       Regulator runs in a more efficient mode for light
+ *             loads. Can be used for devices that have a low power
+ *             requirement during periods of inactivity. This mode
+ *             may be more noisy than NORMAL and may not be able
+ *             to handle fast load switching.
+ *
+ *  STANDBY    Regulator runs in the most efficient mode for very
+ *             light loads. Can be used by devices when they are
+ *             in a sleep/standby state. This mode is likely to be
+ *             the most noisy and may not be able to handle fast load
+ *             switching.
+ *
+ * NOTE: Most regulators will only support a subset of these modes. Some
+ * will only just support NORMAL.
+ *
+ * These modes can be OR'ed together to make up a mask of valid register modes.
