Subject: [PATCH 2/3] dt-bindings: hwlock: sun6i: Add compatible for Allwinner D1
Date: Sun, 27 Sep 2026 09:56:25 +0700 [thread overview]
Message-ID: <20260927025626.69614-3-tien.nguyenminh@embeddedlinux.blog> (raw)
In-Reply-To: <20260927025626.69614-1-tien.nguyenminh@embeddedlinux.blog>
The D1 and T113 have a hardware spinlock with the register layout the
sun6i driver handles. Add a compatible for it, with the A31 one as
fallback.
