Subject: [PATCH 2/3] dt-bindings: watchdog: sunxi: Add compatible for D1
Date: Sun, 25 Jul 2021 22:51:42 -0500	[thread overview]
Message-ID: <20210726035143.53132-2-samuel@sholland.org> (raw)
In-Reply-To: <20210726035143.53132-1-samuel@sholland.org>

D1 keeps the same register layout and clock sources as the R329, but it
adds a key field which must be set to update the watchdog's "CFG" and
"MODE" registers. Therefore it is not backward-compatible.
