Stephen Warren d0f1c7ffaa ARM: bcm2835: implement machine restart hook ... Implement the machine restart hook using the SoC's watchdog timer module. To support this, define a DT binding for the watchdog module, and add it to the device tree. The downstream rpi-split branch contains a full watchdog timer driver implementation, which also implements the restart hook. However, the restart function is largely separate from the watchdog driver, so for simplicity, the restart hook is implemented here directly in the main machine source file. Overall structure (separate setup/restart) functions derived from the picoxcell ARM support. Watchdog register IO sequence taken from code by Simon Arlott. Note that the watchdog module is not documented in BCM2835-ARM-Peripherals.pdf. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>		2012-10-25 20:42:36 -06:00
