* | | Input: samsung-keypad - don't synchronise with runtime PM putMark Brown2012-01-231-3/+3
| |/ |/| | | | | | | | | | | | | | | | | We don't actually care if the device has been runtime suspended immediately so we can just drop the reference without waiting for any state change to be implemented. This may allow us to avoid some suspend/resume cycles and is a bit more friendly to the rest of the system.

* | Input: samsung-keypad - implement runtime power management supportMark Brown2011-12-301-7/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When runtime power management is enabled put the Samsung keypad driver into suspend mode with wakeups disabled whenever the device is open but a key is not actually been pressed. As well as saving a trivial amount of power this will support the use of SoC wide idle modes which put the entire device into a retention mode and use explicit wakeup sources to exit. Since not all of the interrupt controllers used with the driver support set_irq_wake() (though they all do the right thing) and there's a nasty WARN() when we disable wake after failing to enable it keep track of the current wake status from runtime PM and only disable wake if we managed to enable it; I'm not entirely sure why this doesn't affect the existing uses of the API in the driver. System suspend is unaffected as the driver core will runtime resume any suspended devices prior to system suspend.

| | | | | | | | | | | | | | | | There is nothing in keypad platform definitions that requires the driver be complied on Samsung platform only, so let's move them out of the platform subdirectory and relax the dependencies. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
