This adds support for the regulators found in the AB3100 Mixed-Signal IC. It further also defines platform data for the ST-Ericsson U300 platform and extends the AB3100 MFD driver so that platform/board data with regulation constraints and an init function can be passed down all the way from the board to the regulators.

This adds the _interruptible suffix to the AB3100 accessor functions on par with mutex_lock_interruptible() that's used for blocking simultaneous calls to the AB3100 acessor functions. Since these accesses are slow on a 100kHz I2C bus and may line up waiting for the mutex, we need to handle interruption by system shutdown or kill signals and may just as well denote that in the function names.

The WM831x series of devices provide three types of LDO: - General purpose LDOs supporting voltages from 0.9-3.3V - High performance analogue LDOs supporting voltages from 1-3.5V - Very low power consumption LDOs intended to support always on functionality. This patch adds support for all three kinds of LDO. Each regulator is probed as an individual platform device with resources used to provide the register map location of the regulator. Mixed hardware and software control of regulators is not current supported.

The WM831x series of devices all have 3 DC-DC buck convertors. This driver implements software control for these regulators via the regulator API.

Add support for the GPIO pins on the WM831x. No direct support is currently supplied for configuring non-gpiolib functionality such as pull configuration and alternate functions, soft configuration of these will be provided in a future patch. Currently use of these pins as interrupts is not supported due to the ongoing issues with generic irq not support interrupt controllers on interrupt driven buses. Users can directly request the interrupts with the wm831x-specific APIs currently provided if required.

The current settings which can be used with the WM831x current sinks can't easily be mapped between register values and currents at run time without a lookup table since the values scale logarithmically to match the way the human eye interprets brightness. This lookup table is inclided in the core since several drivers need to use it. Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: NSamuel Ortiz <sameo@linux.intel.com>

The WM831x series of devices use OTP (One Time Programmable, a type of PROM) to store system configuration. At run time this data is visible via registers. Currently the only explicitly supported feature is that the unique ID provided by every WM831x device is exported to user space via sysfs. Other configuration data may be read by system-specific code in the pre_init() and post_init() platform data operations.

The WM831x contains an auxiliary ADC with a number of switchable inputs which is used to monitor some of the voltages and temperatures in the system and has some external inputs which can be used for machine specific purposes. Provide an API allowing drivers to read values from the ADC. An internal reference voltage is provided to allow callibration of the ADC. This is used to calibrate the device at startup. The hardware also supports continuous readings and digital comparators. These are not yet supported by the driver.

The WM831x includes an interrupt controller managing interrupts for the various functions on the chip. This patch adds support for the core interrupt block on the device. Ideally this would be supported by genirq, particularly for the GPIOs, but currently genirq is unable to cope with controllers on interrupt driven buses so we cut'n'paste the generic interface. Once genirq is able to cope chips like this it should be a case of filing the prefixes off the code and redoing wm831x-irq.c to move over.

The WM831x series of devices are register compatible processor power management subsystems, providing regulator and power path management facilities along with other services like watchdog, RTC and touch panel controllers.

Provide basic support for MFDs having multiple cells of a given type with different IDs by adding an id to the mfd_cell structure and then adding that to the id passed in to mfd_add_devices(). As it stands this approach requires that MFDs using this feature deal with ensuring that there aren't any ID collisions resulting from multiple MFDs of the same type being instantiated. This needs to happen with the existing code too, but with this approach there is a knock on effect on the IDs for non-duplicated devices.

Using the default kernel "events" workqueue causes problems with synchronous adc readings if initiated from some task on the same workqueue. I had a deadlock trying to use pcf50633_adc_sync_read from a power_supply class driver because the reading was initiated from the workqueue and it waited for the irq processing to complete (to get the result) and that was put on the same workqueue.

The PCAP Asic as present on EZX phones is a multi function device with voltage regulators, ADC, touch screen controller, RTC, USB transceiver, leds controller, and audio codec. It has two SPI ports, typically one is connected to the application processor and another to the baseband, this driver provides read/write functions to its registers, irq demultiplexer and ADC queueing/abstraction. This chip is used on a lot of Motorola phones, it was manufactured by TI as a custom product with the name PTWL93017, later this design evolved into the ATLAS PMIC from Freescale (MC13783).

This driver requests a clock that usually is supplied by the MFD in which the DS1WM is contained. Currently, it is impossible for a MFD to register their clocks with the generic clock API due to different implementations across architectures. For now, this patch removes the clock handling from DS1WM altogether, trusting that the MFD enable/disable functions will switch the clock if needed. The clock rate is obtained from a new parameter in driver_data. Signed-off-by: NPhilipp Zabel <philipp.zabel@gmail.com> Signed-off-by: NSamuel Ortiz <sameo@openedhand.com>

The battery charger state machine switches into charging mode when the battery voltage falls below 96% of a battery float voltage. But the voltage drop in Li-ion batteries is marginal(1~2 %) till about 80% of its capacity - which means, after a BATFULL, charging won't be restarted until 80%. This work_struct function restarts charging at regular intervals to make sure the battery doesn't discharge too much.
