2010-10-29mfd: Use i2c_client as an argument on MAX8998 i2c routinesJoonyoung Shim3-46/+30
The MAX8998 chip have regulator and rtc features. The i2c slave address of regulator and rtc is different, so needs each i2c client on i2c operation functions. Also, this patch exports i2c operation functions instead of callback to make easy to read.

2010-10-29gpio: Add bitmask to block requests to unavailable stmpe GPIOsWolfram Sang2-0/+11
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.

2010-10-29regulator: avoid deadlock when disabling regulator with supplyJeffrey Carlyle1-9/+26
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).

2010-10-29MAX8952 PMIC Driver Initial ReleaseMyungJoo Ham4-0/+504
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.

Add support for the IT8721F/IT8758E. These new chips differ from the older IT87xxF chips in the following ways: * ADC LSB is 12 mV instead of 16 mV. * PWM values are 8-bit instead of 7-bit.
