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