2010-10-29mfd: Align ab8500 with the abx500 interfaceMattias Wallin
This patch makes the ab8500 mixed signal chip expose the same interface for register access as the ab3100, ab3550 and ab5500 chip. The ab8500_read() and ab8500_write() is removed and replaced with abx500_get_register_interruptible() and abx500_set_register_interruptible().

2010-10-29mmc: Allow the platform to specify the sh_mmcif get_cd handlerArnd Hannemann
In some platforms (e.g. AP4EVB) the card detect pin of a slot is not directly connected to the sh_mmcif controller, so that polling needs to be used. To overcome the overhead induced by querying the controller on each poll cycle, card detection can be handled in the platform code more efficiently. This patch exposes a get_cd hook for that purpose.

On some platforms (e.g. AP4EVB) the card detect pin of a slot is not directly connected to the sdhi hardware, so that polling needs to be used with tmio_mmc and card detection is handled in the platform code.

2010-10-29gpio: Add bitmask to block requests to unavailable stmpe GPIOsWolfram Sang
GPIOs on these controller are multi-functional. If you decided to use some of them e.g. as input channels for the ADC, you surely don't want those pins to be reassigned as simple GPIOs (which may be triggered even from userspace via 'export'). Same for the touchscreen controller pins. Since knowledge about the hardware is needed to decide which GPIOs to reserve, let this bitmask be inside platform_data and provide some defines to assist potential users.

2010-10-28regulator: avoid deadlock when disabling regulator with supplyJeffrey Carlyle
I have a regulator A that sets regulator B as its supply. When I call set_supply to add B as the supply for A, regulator A gets added to the supply_list for regulator B. When I call regulator_disable(A), I end up with a call chain like this: regulator_disable(A) > mutex_lock(A) > _regulator_disable(A) >> _regulator_disable(B) >>> _notifier_call_chain(B) >>>> mutex_lock(A) Which results in dead lock since we are trying to acquire the mutex lock for regulator A which we already hold. This patch addresses this issue by moving the call to disable regulator B outside of the lock aquired inside the initial call to regulator_disable. This change also addresses the issue of not acquiring the mutex for regulator B before calling _regulator_disable(B).

2010-10-28MAX8952 PMIC Driver Initial ReleaseMyungJoo Ham
MAX8952 PMIC is used to provide voltage output between 770mV - 1400mV with DVS support. In this initial release, users can set voltages for four DVS modes, RAMP delay values, and SYNC frequency. Controlling FPWM/SYNC_MODE/Pull-Down/Ramp Modes and reading CHIP_ID is not supported in this release. If GPIO of EN is not valid in platform data, the driver assumes that it is always-on. If GPIO of VID0 or VID1 is invalid, the driver pulls down VID0 and VID1 to fix DVS mode as 0 and disables DVS support. We assume that V_OUT is capable to provide every voltage from 770mV to 1.40V in 10mV steps although the data sheet has some ambiguity on it.
