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
