clockevents/drivers/stm32: Migrate to new 'set-state' interface

2015-08-10T09:40:48Z

Migrate stm32 driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED.

clockevents/drivers: Add STM32 Timer driver

2015-06-02T10:10:15Z

STM32 MCUs feature 16 and 32 bits general purpose timers with prescalers. The drivers detects whether the time is 16 or 32 bits, and applies a 1024 prescaler value if it is 16 bits. Reviewed-by: Linus Walleij Tested-by: Chanwoo Choi Signed-off-by: Maxime Coquelin Signed-off-by: Daniel Lezcano
