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.
