Subject: [PATCH v4 0/9] Atmel System Timer cleanups

This patch set 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.

This is based on 4.0-rc1 and will have two merge conflicts with my cleanup #1 in
mach-at91/at91rm9200.c

Changes in v4:
 - Added MODULE_* metadata in at91rm9200-reset
 - Proper copyright in at91rm9200-reset
 - Use BIT() in atmel-st.h
 - changed MODULE_ALIAS in at91rm9200_wdt.c

Changes in v3:
 - stop using an mfd and get the syscon directly from the watchdog driver
 - introduce a proper reset driver to handle reset

Changes in v2:
 - cleaned up more includes in the watchdog driver
 - stop using if OF when selecting CLKSRC_OF
 - stop initializing .owner


Alexandre Belloni (9):
  ARM: at91/dt: declare atmel,at91rm9200-st as a syscon
  mfd: syscon: Add atmel system timer registers definition
  watchdog: at91rm9200: use the system timer syscon
  power: reset: Add AT91RM9200 reset driver
  ARM: at91: at91rm9200: remove deprecated arm_pm_restart
  ARM: at91: time: move the system timer driver to drivers/clocksource
  clocksource: atmel-st: properly initialize driver
  clocksource: atmel-st: use syscon/regmap
  ARM: at91: remove useless include
