2012-02-15mfd: tps6586x: Natively register pm_power_offDan Willemsen
Instead of forcing the board files to register this themselves, just add a bool to the platform data to let the board files opt into this.

2011-11-30mfd: tps6586x: add suspend/resume handlersVarun Wadekar
if the system is woken by an alarm, tps' irq handler gets called and it tries to communicate on i2c. i2c adapters resume later which causes communication failures in tps' irq handler. the right way is to disable tps' irq while suspending in order to avoid such i2c communication failures.

when tps6586x is put into sleep mode, it powers off ldos. Add an api to put tps6586x in sleep mode by resetting EXITSLREQ and setting SLEEP_MODE in SUPPLYENE register.

2011-11-30ARM: tegra: tps6586x: add empty function direction_inputPritesh Raithatha
-on reset default direction is in NOT_CONFIGURED (neither input nor output) mode. -as tps6586x driver has not implemented direction_input, gpiolib sysfs only creates a value node not any direction node for each gpios. so from user space there is no way to set direction (or to call function tps6586x_update). -by adding empty function for direction_input solves the above problem by providing direction node in sysfs.

2011-05-26mfd: Fix tps6586x GPIO value settingVincent Palatin
In the current code, every time we set a TPS6586x GPIO pin, the tps6586x_gpio_set function is resetting all other GPIO pins. We need to update the right GPIOxOUT bit of the GPIOSET2 register instead of overriding the full value. Tested by setting sequentially GPIO2 and GPIO3 and verifying the pins voltage.

2011-01-14mfd: Remove tps6586x device ID checkStephen Warren
... and convert it to a dev_info print at probe time. There are many variants of this chip with different values of VERSIONCRC. The set of values is large, and not useful to enumerate. All are SW compatible. The difference lies in default settings of the various power rails, and other similar differences. The driver, or clients of the driver, shouldn't be affected by this, since all rails should be programmed into the desired state in all cases for correct operation.
