complicated in the next patch.

watchdog: uniphier: add UniPhier watchdog driver

2017-07-03T11:58:55+00:00

Add a watchdog driver for Socionext UniPhier series SoC.
Note that the timeout value for this device must be a power
of 2 because of the specification.

watchdog: cadence_wdt: make of_device_ids const.

2017-07-03T11:53:43+00:00

of_device_ids are not supposed to change at runtime. All functions
working with of_device_ids provided by  work with const
of_device_ids. So mark the non-const structs as const.
