2011-05-05regulator: recursive locking detected when notifying supply regulatorsRobert Rosengren
A "possible recursive locking detected"-warning is issued when a regulator has supply regulators and it shall notify the call chain. This is due to locking mutexes of the same lock class, i.e. the locks reside in the regulator_dev struct. Since this is valid behavior for the regulators, this patch changes the mutex lock into nested, as suggested in lockdep-design.txt.

2010-11-10regulator: 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).

2010-10-04regulator: Default GPIO controlled WM8994 regulators to disabledJoonyoung Shim
commit c4604e49c1a5832a58789a22eba7ca982933e1be upstream. This ensures that if the GPIO was not enabled prior to the driver starting the regulator API will insert the required powerup ramp delay when it enables the regulator. The gpiolib API does not provide this information.

2010-07-28regulator: tps6507x: allow driver to use DEFDCDC{2,3}_HIGH registerAnuj Aggarwal
Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> In TPS6507x, depending on the status of DEFDCDC{2,3} pin either DEFDCDC{2,3}_LOW or DEFDCDC{2,3}_HIGH register needs to be read or programmed to change the output voltage. The current driver assumes DEFDCDC{2,3} pins are always tied low and thus operates only on DEFDCDC{2,3}_LOW register. This need not always be the case (as is found on OMAP-L138 EVM). Unfortunately, software cannot read the status of DEFDCDC{2,3} pins. So, this information is passed through platform data depending on how the board is wired.

2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

2010-05-28mfd: AB3100 register access change to abx500 APIMattias Wallin
The interface for the AB3100 is changed to make way for the ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson Analog Baseband chips. The register access functions are moved out to a separate struct abx500_ops. In this way the interface is moved from the implementation and the sub functionality drivers can keep their interface intact when chip infrastructure and communication mechanisms changes. We also define the AB3550 device IDs and the AB3550 platform data struct and convert the catenated 32bit event to an array of 3 x 8bits.
