2010-10-29mfd: Add mc13892 support to mc13xxxUwe Kleine-König4-746/+848
mc13892 is the companion PMIC for Freescale's i.MX51. It's similar enough to mc13782 to support it in a single driver. This patch introduces enough compatibility cruft to keep all users of the superseded mc13783 driver unchanged.

2010-10-29mfd: Remove obsolete mc13783 private dataUwe Kleine-König1-18/+9
The regulator driver was converted to get the needed data directly from platform_data by a10099b (regulator/mc13783: various cleanups) so regulators and num_regulators can go away. Then apart from the flag indicating that the adc does a conversion, flags is only a copy of the flags member of platform_data. This flag isn't needed to be returned by mc13783_get_flags, so mc13783_get_flags now gets the flags from platform_data, too and the driver private member is renamed for clearity.

2010-10-29mmc: Allow the platform to specify the sh_mmcif get_cd handlerArnd Hannemann1-0/+12
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.

2010-10-29gpio: Add bitmask to block requests to unavailable stmpe GPIOsWolfram Sang1-0/+5
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 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).
