[PATCH v6 12/19] watchdog: orion: Add per-compatible watchdog start implementation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




To handle differences between SoCs this commit adds per-compatible
string start() function for the watchdog kick-off. This is preparation
work and makes no functionality changes to the current driver.
