   4 Subject: [PATCH] arm64: dts: allwinner: a64: Add watchdog
   5
   6 Add a watchdog node for the A64, automatically enabled on all boards.
   7 Since the device is compatible with an existing driver, we only reserve
   8 a new compatible string to be used together with the fall back.
   9 Tested on Olimex Teres-I.
