Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC driver changes from Olof Johansson:
 "This is a rather large set of patches for device drivers that for one
  reason or another the subsystem maintainer preferred to get merged
  through the arm-soc tree.  There are both new drivers as well as
  existing drivers that are getting converted from platform-specific
  code into standalone drivers using the appropriate subsystem specific
  interfaces.

  In particular, we can now have pinctrl, clk, clksource and irqchip
  drivers in one file per driver, without the need to call into platform
  specific interface, or to get called from platform specific code, as
  long as all information about the hardware is provided through a
  device tree.

  Most of the drivers we touch this time are for clocksource.  Since now
  most of them are part of drivers/clocksource, I expect that we won't
  have to touch these again from arm-soc and can let the clocksource
  maintainers take care of these in the future.

  Another larger part of this series is specific to the exynos platform,
  which is seeing some significant effort in upstreaming and
  modernization of its device drivers this time around, which
  unfortunately is also the cause for the churn and a lot of the merge
  conflicts.

  There is one new subsystem that gets merged as part of this series:
  the reset controller interface, which is a very simple interface for
  taking devices on the SoC out of reset or back into reset.  Patches to
  use this interface on i.MX follow later in this merge window, and we
  are going to have other platforms (at least tegra and sirf) get
  converted in 3.11.  This will let us get rid of platform specific
  callbacks in a number of platform independent device drivers."

+* Samsung Exynos4 Clock Controller
+
+The Exynos4 clock controller generates and supplies clock to various controllers
+within the Exynos4 SoC. The clock binding described here is applicable to all
+SoC's in the Exynos4 family.
+
+Required Properties:
+
+- comptible: should be one of the following.
+  - "samsung,exynos4210-clock" - controller compatible with Exynos4210 SoC.
+  - "samsung,exynos4412-clock" - controller compatible with Exynos4412 SoC.
+
+- reg: physical base address of the controller and length of memory mapped
+  region.
+
+- #clock-cells: should be 1.
+
+The following is the list of clocks generated by the controller. Each clock is
+assigned an identifier and client nodes use this identifier to specify the
+clock which they consume. Some of the clocks are available only on a particular
+Exynos4 SoC and this is specified where applicable.

+NVIDIA Tegra114 Clock And Reset Controller
+
+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The CAR (Clock And Reset) Controller on Tegra is the HW module responsible
+for muxing and gating Tegra's clocks, and setting their rates.
+
+Required properties :
+- compatible : Should be "nvidia,tegra114-car"
+- reg : Should contain CAR registers location and length
+- clocks : Should contain phandle and clock specifiers for two clocks:
+  the 32 KHz "32k_in", and the board-specific oscillator "osc".
+- #clock-cells : Should be 1.
+  In clock consumers, this cell represents the clock ID exposed by the CAR.
+
+  The first 160 clocks are numbered to match the bits in the CAR's CLK_OUT_ENB
+  registers. These IDs often match those in the CAR's RST_DEVICES registers,
+  but not in all cases. Some bits in CLK_OUT_ENB affect multiple clocks. In
+  this case, those clocks are assigned IDs above 160 in order to highlight
+  this issue. Implementations that interpret these clock IDs as bit values
+  within the CLK_OUT_ENB or RST_DEVICES registers should be careful to
+  explicitly handle these special cases.
+
+  The balance of the clocks controlled by the CAR are assigned IDs of 160 and
+  above.

+Samsung S3C24XX Interrupt Controllers
+
+The S3C24XX SoCs contain a custom set of interrupt controllers providing a
+varying number of interrupt sources. The set consists of a main- and sub-
+controller and on newer SoCs even a second main controller.
+
+Required properties:
+- compatible: Compatible property value should be "samsung,s3c2410-irq"
+  for machines before s3c2416 and "samsung,s3c2416-irq" for s3c2416 and later.
+
+- reg: Physical base address of the controller and length of memory mapped
+  region.
+
+- interrupt-controller : Identifies the node as an interrupt controller
+
+- #interrupt-cells : Specifies the number of cells needed to encode an
+  interrupt source. The value shall be 4 and interrupt descriptor shall
+  have the following format:
+      <ctrl_num parent_irq ctrl_irq type>
+
+  ctrl_num contains the controller to use:
+      - 0 ... main controller
+      - 1 ... sub controller
+      - 2 ... second main controller on s3c2416 and s3c2450
+  parent_irq contains the parent bit in the main controller and will be
+             ignored in main controllers
+  ctrl_irq contains the interrupt bit of the controller
+  type contains the trigger type to use
+
+Example:
+
+        interrupt-controller@4a000000 {
+                compatible = "samsung,s3c2410-irq";

+Device tree bindings for NOR flash connect to TI GPMC
+
+NOR flash connected to the TI GPMC (found on OMAP boards) are represented as
+child nodes of the GPMC controller with a name of "nor".
+
+All timing relevant properties as well as generic GPMC child properties are
+explained in a separate documents. Please refer to
+Documentation/devicetree/bindings/bus/ti-gpmc.txt
+
+Required properties:
+- bank-width:           Width of NOR flash in bytes. GPMC supports 8-bit and
+                        16-bit devices and so must be either 1 or 2 bytes.
+- compatible:           Documentation/devicetree/bindings/mtd/mtd-physmap.txt
+- gpmc,cs-on-ns:                Chip-select assertion time
+- gpmc,cs-rd-off-ns:    Chip-select de-assertion time for reads
+- gpmc,cs-wr-off-ns:    Chip-select de-assertion time for writes
+- gpmc,oe-on-ns:        Output-enable assertion time
+- gpmc,oe-off-ns:       Output-enable de-assertion time
+- gpmc,we-on-ns         Write-enable assertion time
+- gpmc,we-off-ns:       Write-enable de-assertion time
+- gpmc,access-ns:       Start cycle to first data capture (read access)
+- gpmc,rd-cycle-ns:     Total read cycle time
+- gpmc,wr-cycle-ns:     Total write cycle time
+- linux,mtd-name:       Documentation/devicetree/bindings/mtd/mtd-physmap.txt
+- reg:                  Chip-select, base address (relative to chip-select)
+                        and size of NOR flash. Note that base address will be
+                        typically 0 as this is the start of the chip-select.
+
+Optional properties:
+- gpmc,XXX              Additional GPMC timings and settings parameters. See
+                        Documentation/devicetree/bindings/bus/ti-gpmc.txt

+Device tree bindings for Ethernet chip connected to TI GPMC
+
+Besides being used to interface with external memory devices, the
+General-Purpose Memory Controller can be used to connect Pseudo-SRAM devices
+such as ethernet controllers to processors using the TI GPMC as a data bus.
+
+Ethernet controllers connected to TI GPMC are represented as child nodes of
+the GPMC controller with an "ethernet" name.
+
+All timing relevant properties as well as generic GPMC child properties are
+explained in a separate documents. Please refer to
+Documentation/devicetree/bindings/bus/ti-gpmc.txt
+
+For the properties relevant to the ethernet controller connected to the GPMC
+refer to the binding documentation of the device. For example, the documentation
+for the SMSC 911x is Documentation/devicetree/bindings/net/smsc911x.txt
+
+Child nodes need to specify the GPMC bus address width using the "bank-width"
+property but is possible that an ethernet controller also has a property to
+specify the I/O registers address width. Even when the GPMC has a maximum 16-bit
+address width, it supports devices with 32-bit word registers.
+For example with an SMSC LAN911x/912x controller connected to the TI GPMC on an
+OMAP2+ board, "bank-width = <2>;" and "reg-io-width = <4>;".
+
+Required properties:
+- bank-width:           Address width of the device in bytes. GPMC supports 8-bit
+                        and 16-bit devices and so must be either 1 or 2 bytes.
+- compatible:           Compatible string property for the ethernet child device.
+- gpmc,cs-on:           Chip-select assertion time
+- gpmc,cs-rd-off:       Chip-select de-assertion time for reads
+- gpmc,cs-wr-off:       Chip-select de-assertion time for writes
+- gpmc,oe-on:           Output-enable assertion time
+- gpmc,oe-off           Output-enable de-assertion time
+- gpmc,we-on:           Write-enable assertion time
+- gpmc,we-off:          Write-enable de-assertion time
+- gpmc,access:          Start cycle to first data capture (read access)
+- gpmc,rd-cycle:        Total read cycle time
+- gpmc,wr-cycle:        Total write cycle time
+- reg:                  Chip-select, base address (relative to chip-select)
+                        and size of the memory mapped for the device.
+                        Note that base address will be typically 0 as this
+                        is the start of the chip-select.
+
+Optional properties:

+phrase "pin configuration node".
+
+Each pin configuration node lists the pin(s) to which it applies, and one or

+configuration. Each subnode only affects those parameters that are explicitly

+
+Optional subnode-properties:
+- wm,function: Integer, containing the function to mux to the pin(s):

+  1: GPIO out
+  2: alternate
+
+- wm,pull: Integer, representing the pull-down/up to apply to the pin(s):

+= Reset Signal Device Tree Bindings =
+
+This binding is intended to represent the hardware reset signals present
+internally in most IC (SoC, FPGA, ...) designs. Reset signals for whole
+standalone chips are most likely better represented as GPIOs, although there
+are likely to be exceptions to this rule.
+
+Hardware blocks typically receive a reset signal. This signal is generated by
+a reset provider (e.g. power management or clock module) and received by a
+reset consumer (the module being reset, or a module managing when a sub-
+ordinate module is reset). This binding exists to represent the provider and
+consumer, and provide a way to couple the two together.
+
+A reset signal is represented by the phandle of the provider, plus a reset
+specifier - a list of DT cells that represents the reset signal within the
+provider. The length (number of cells) and semantics of the reset specifier
+are dictated by the binding of the reset provider, although common schemes
+are described below.
+
+A word on where to place reset signal consumers in device tree: It is possible
+in hardware for a reset signal to affect multiple logically separate HW blocks
+at once. In this case, it would be unwise to represent this reset signal in
+the DT node of each affected HW block, since if activated, an unrelated block
+may be reset. Instead, reset signals should be represented in the DT node
+where it makes most sense to control it; this may be a bus node if all
+children of the bus are affected by the reset signal, or an individual HW
+block node for dedicated reset signals. The intent of this binding is to give
+appropriate software access to the reset signals in order to manage the HW,
+rather than to slavishly enumerate the reset signal that affects each HW
+block.
+
+= Reset providers =
+
+Required properties:
+#reset-cells:   Number of cells in a reset specifier; Typically 0 for nodes
+                with a single reset output and 1 for nodes with multiple
+                reset outputs.
+
+For example:
+
+        rst: reset-controller {
+                #reset-cells = <1>;
+        };
+
+= Reset consumers =
+
+Required properties:
+resets:         List of phandle and reset specifier pairs, one pair
+                for each reset signal that affects the device, or that the
+                device manages. Note: if the reset provider specifies '0' for
+                #reset-cells, then only the phandle portion of the pair will
+                appear.
+
+Optional properties:
+reset-names:    List of reset signal name strings sorted in the same order as
+                the resets property. Consumers drivers will use reset-names to
+                match reset signal names with reset specifiers.
+
+For example:
+
+        device {
+                resets = <&rst 20>;
+                reset-names = "reset";
+        };
+
+This represents a device with a single reset signal named "reset".
+
+        bus {
+                resets = <&rst 10> <&rst 11> <&rst 12> <&rst 11>;
+                reset-names = "i2s1", "i2s2", "dma", "mixer";
+        };
+
+This represents a bus that controls the reset signal of each of four sub-
+ordinate devices. Consider for example a bus that fails to operate unless no
+child device has reset asserted.

+Samsung's Multi Core Timer (MCT)
+
+The Samsung's Multi Core Timer (MCT) module includes two main blocks, the
+global timer and CPU local timers. The global timer is a 64-bit free running
+up-counter and can generate 4 interrupts when the counter reaches one of the
+four preset counter values. The CPU local timers are 32-bit free running
+down-counters and generate an interrupt when the counter expires. There is
+one CPU local timer instantiated in MCT for every CPU in the system.
+
+Required properties:
+
+- compatible: should be "samsung,exynos4210-mct".
+  (a) "samsung,exynos4210-mct", for mct compatible with Exynos4210 mct.
+  (b) "samsung,exynos4412-mct", for mct compatible with Exynos4412 mct.
+
+- reg: base address of the mct controller and length of the address space
+  it occupies.
+
+- interrupts: the list of interrupts generated by the controller. The following
+  should be the order of the interrupts specified. The local timer interrupts
+  should be specified after the four global timer interrupts have been
+  specified.
+
+        0: Global Timer Interrupt 0
+        1: Global Timer Interrupt 1
+        2: Global Timer Interrupt 2
+        3: Global Timer Interrupt 3

+        5: Local Timer Interrupt 1
+        6: ..
+        7: ..
+        i: Local Timer Interrupt n
+
+Example 1: In this example, the system uses only the first global timer
+           interrupt generated by MCT and the remaining three global timer
+           interrupts are unused. Two local timer interrupts have been
+           specified.
