2015-02-17watchdog: da9063: Add restart handler supportGeert Uytterhoeven1-1/+31
Register a restart handler for the da9063 watchdog. System restart is triggered by sending the shutdown command to the PMIC. As more-suitable restart handlers may exist, the priority of the watchdog restart handler is set to 128. The actual restart method was inspired by a platform-specific patch from the BSP by Hisashi Nakamura <hisashi.nakamura.ak@renesas.com>.

Improve power management operations(suspend and resume) as part of dev_pm_ops for IMX2 watchdog driver. If PM will be supported, please make sure that the wdev->clk could disable the watchdog's counter input clock source or can mask watchdog's reset request to the core. If watchdog is still used by consumers and resumes from deep sleep state, we need to restart the watchdog again without enabling the timer. If watchdog been has started --> stopped by the consumers and resumes from non-deep sleep state, then start the timer again. If watchdog has been started --> stopped by the consumers and resumes from deep sleep state, will do nothing. The watchdog will be restarted by consumers next time to be used.
