[PATCH v3 0/2] add a new driver to support SAMA5D4 watchdog timer

[Wenyou Yang]

Hello,

Because the watchdog WDT_MR register can be written more than once,
its work mechanism is different from the at91sam9260 watchdog driver.
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.

Thank for Guenter's review, the version 2.0 changes are listed as below.

Changes from v2.0
 1./ Use a specific driver name, at91_sama5d4_wdt.c.
 2./ Remove '-' at the end of macro name and unnecessary check.
 3./ Use alphabetic order for include files.
