This patch sets cleans up the system timer driver.
The main goal is to get rid of the mach/ headers dependency. At the same time,
it introduces proper probing and locking (using a regmap) for the watchdog
driver.
Changes in v3:
- moved the watchdog regmap_st allocation after the multiple probe check
- check whether regmap_st is NULL in the watchdog driver
Changes in v2:
- cleaned up more includes in the watchdog driver
- stop using if OF when selecting CLKSRC_OF
- stop initializing .owner
Alexandre Belloni (8):
ARM: at91/dt: declare atmel,at91rm9200-st as a syscon
mfd: Add atmel-st driver
watchdog: at91rm9200: use the regmap from mfd
ARM: at91: time: move the system timer driver to drivers/clocksource
ARM: at91: move the restart function to the system timer driver
clocksource: atmel-st: properly initialize driver
clocksource: atmel-st: use syscon/regmap
ARM: at91: remove useless include
