[PATCH v2 0/2] add a new driver to support SAMA5D4 watchdog timer

[Wenyou Yang]

Hello,

Thank for Guenter's advice, add a new driver to support SAMA5D4 watchdog timer.

Because the watchdog WDT_MR register can be written more than once, its work
mechanism is different from the previous one. Open the device file to enable
the watchdog hardware, close to disable it, and ping it from the user space
directly to keep it alive.

Best Regards,
Wenyou Yang
