Subject: [PATCH 3/3] riscv: dts: allwinner: d1-t113: Add the hardware spinlock
Date: Sun, 27 Sep 2026 09:56:26 +0700	[thread overview]
Message-ID: <20260927025626.69614-4-tien.nguyenminh@embeddedlinux.blog> (raw)
In-Reply-To: <20260927025626.69614-1-tien.nguyenminh@embeddedlinux.blog>

Add the hardware spinlock of the D1 and T113. It goes in
sunxi-d1-t113.dtsi rather than sunxi-d1s-t113.dtsi, as the D1s manual
has no spinlock in its memory map.
