Subject: [PATCH v2 2/3] dt-bindings: watchdog: sunxi: Add compatible for D1
Date: Wed, 4 Aug 2021 23:57:15 -0500 [thread overview]
Message-ID: <20210805045716.46141-2-samuel@sholland.org> (raw)
In-Reply-To: <20210805045716.46141-1-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.
Reviewed-by: Rob Herring <robh@kernel.org>
