Subject: [PATCH 5/7] arm64: dts: allwinner: sun50i-h6: Add missing SRAM region for video engine
Date: Tue,  5 May 2026 21:48:09 +0800	[thread overview]
Message-ID: <20260505134812.408316-6-wens@kernel.org> (raw)
In-Reply-To: <20260505134812.408316-1-wens@kernel.org>

The SRAM C region contains a partial alias to the VE SRAM already
referenced by the video engine. To avoid access through this alias
window, the region should also be claimed by the video engine.

Add a reference to the SRAM C region to the video engine node.

Fixes: b542570e5605 ("arm64: dts: allwinner: h6: Add Video Engine node")
