| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the core of the WL1273 FM radio driver, it connects the two child modules. The two child drivers are drivers/media/radio/radio-wl1273.c and sound/soc/codecs/wl1273.c. The radio-wl1273 driver implements the V4L2 interface and communicates with the device.

* | regulator: MAX8997/8966 supportMyungJoo Ham2011-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch supports PMIC/Regulator part of MAX8997/MAX8966 MFD. In this initial release, selecting voltages or current-limit and switching on/off the regulators are supported. Controlling voltages for DVS with GPIOs is not implemented fully and requires more considerations: it controls multiple bucks (selection of 1, 2, and 5) at the same time with SET1~3 gpios. Thus, when DVS-GPIO is activated, we lose the ability to control the voltage of a single buck regulator independently; i.e., contolling a buck affects other two bucks. Therefore, using the conventional regulator framework directly might be problematic. However, in this driver, we try to choose a setting without such side effect of affecting other regulators and then try to choose a setting with the minimum side effect (the sum of voltage changes in other regulators). On the other hand, controlling all the three bucks simultenously based on the voltage set table may help build cpufreq and similar system more robust; i.e., all the three voltages are consistent every time without glitches during transition.

* | mfd: Reentrance and revamp ab8500 gpadc fetching interfaceDaniel Willerud2011-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This revamps the interface so that AB8500 GPADCs are fetched by name. Probed GPADCs are added to a list and this list is searched for a matching GPADC. This makes it possible to have multiple AB8500 GPADC instances instead of it being a singleton, and rids the need to keep a GPADC pointer around in the core AB8500 MFD struct. Currently the match is made to the device name which is by default numbered from the device instance such as "ab8500-gpadc.0" but by using the .init_name field of the device a more intiutive naming for the GPADC blocks can be achieved if desired.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MAX8997/MAX8966 chip is a multi-function device with I2C bussses. The chip includes PMIC, RTC, Fuel Gauge, MUIC, Haptic, Flash control, and Battery (charging) control. This patch is an initial release of a MAX8997/8966 driver that supports to enable the chip with its primary I2C bus that connects every device mentioned above except for Fuel Gauge, which uses another I2C bus. The fuel gauge is not supported by this mfd driver and is supported by a seperated driver of MAX17042 Fuel Gauge (yes, the fuel gauge part is compatible with MAX17042).

* | mfd: add platform_device sharing support for mfdAndres Salomon2011-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds functions to enable platform_device sharing for mfd clients. Each platform driver (mfd client) that wants to share an mfd_cell's platform_device uses the mfd_shared_platform_driver_{un,}register() functions instead of platform_driver_{un,}register(). Along with registering the platform driver, these also register a new platform device with the same characteristics as the original cell, but a different name. Given an mfd_cell with the name "foo", drivers that want to share access to its resources can call mfd_shared_platform_driver_register with platform drivers named (for example) "bar" and "baz". This will register two platform devices and drivers named "bar" and "baz" that share the same cell as the platform device "foo". The drivers can then call "foo" cell's enable hooks (or mfd_shared_cell_enable) to enable resources, and obtain platform resources as they normally would. This deals with platform handling only; mfd driver-specific details, hardware handling, refcounting, etc are all dealt with separately.

* | mfd: Add refcounting support to mfd_cellsAndres Salomon2011-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides convenience functions for sharing of cells across multiple mfd clients. Mfd drivers can provide enable/disable hooks to actually tweak the hardware, and clients can call mfd_shared_cell_{en,dis}able without having to worry about whether or not another client happens to have enabled or disabled the cell/hardware. Note that this is purely optional; drivers can continue to use the mfd_cell's enable/disable hooks for their own purposes, if desired.

All clients have already been changed to use the wrapper function, so this can be a quick single-commit change that only touches things in drivers/mfd.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cell's platform_data is now accessed with a helper function; change clients to use that, and remove the now-unused data_size. Note that mfd-core no longer makes a copy of platform_data, but the mc13xxx-core driver creates the pdata structures on the stack. In order to get around that, the various ARM mach types that set the pdata have been changed to hold the variable in static (global) memory. Also note that __initdata references in aforementioned pdata structs have been dropped. Signed-off-by: Andres Salomon <dilinger@queued.net> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* | mfd: mfd_cell is now implicitly available to ab3550 driverAndres Salomon2011-03-23

* | mfd-core: Unconditionally add mfd_cell to every platform_deviceAndres Salomon2011-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, one would set the mfd_cell's platform_data/data_size to point to the current mfd_cell in order to pass that information along to drivers. This causes the current mfd_cell to always be available to drivers. It also adds a wrapper function for fetching the mfd cell from a platform device, similar to what originally existed for mfd devices. Drivers who previously used platform_data for other purposes can still use it; the difference is that mfd_get_data() must be used to access it (and the pdata structure is no longer allocated in mfd_add_devices). Note that mfd_get_data is intentionally vague (in name) about where the data is stored; variable name changes can come later without having to touch brazillions of drivers.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TI's sequencer serial port (TI-SSP) is a jack-of-all-trades type of serial port device. It has a built-in programmable execution engine that can be programmed to operate as almost any serial bus (I2C, SPI, EasyScale, and others). This patch adds a driver for this controller device. The driver does not expose a user-land interface. Protocol drivers built on top of this layer are expected to remain in-kernel.

* / / mfd: Don't suspend WM8994 if the CODEC is not suspendedMark Brown2011-03-02
|/ / | | | | | | | | | | | | | | | | | | | | | | ASoC supports keeping the audio subsysetm active over suspend in order to support use cases such as audio passthrough from a cellular modem with the main CPU suspended. Ensure that we don't power down the CODEC when this is happening by checking to see if VMID is up and skipping suspend and resume when it is. If the CODEC has suspended then it'll turn VMID off before the core suspend() gets called.

* | mfd: Support LP3974 RTCMyungJoo Ham2011-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first releases of LP3974 have a large delay in RTC registers, which requires 2 seconds of delay after writing to a rtc register (recommended by National Semiconductor's engineers) before reading it. If "rtc_delay" field of the platform data is true, the rtc driver assumes that such delays are required. Although we have not seen LP3974s without requiring such delays, we assume that such LP3974s will be released soon (or they have done so already) and they are supported by "lp3974" without setting "rtc_delay" at the platform data. This patch adds delays with msleep when writing values to RTC registers if the platform data has rtc_delay set.

* | mfd: Provide pm_runtime_no_callbacks flag in cell dataMark Brown2011-01-14
| | | | | | | | | | | | | | | | | | | | | | | | Allow MFD cells to have pm_runtime_no_callbacks() called on them during registration. This causes the runtime PM framework to ignore them, allowing use of runtime PM to suspend the device as a whole even if not all drivers for the MFD can usefully implement runtime PM. For example, RTCs are likely to run continuously regardless of the power state of the system.
