watchdog: sama5d4_wdt: addition of sam9x60 compatible watchdog Add support for SAM9X60 WDT into sama5d4_wdt. This means that this driver gets a flag inside the data struct that represents the sam9x60 support. This flag differentiates between the two hardware blocks, and is set according to the compatible of the driver instantiation.

watchdog: add a driver to support SAMA5D4 watchdog timer From SAMA5D4, the watchdog timer is upgrated with a new feature, which is describled as in the datasheet, "WDT_MR can be written until a LOCKMR command is issued in WDT_CR". That is to say, as long as the bootstrap and u-boot don't issue a LOCKMR command, WDT_MR can be written more than once in the driver. So the SAMA5D4 watchdog driver's implementation is different from the at91sam9260 watchdog driver implemented in file at91sam9_wdt.c. The user application open the device file to enable the watchdog timer hardware, and close to disable it, and set the watchdog timer timeout by seting WDV and WDD fields of WDT_MR register, and ping the watchdog by issuing WDRSTT command to WDT_CR register with hard-coded key.
