Subject: [PATCH v3 5/7] arm64: dts: allwinner: sun50i-h6: Add missing SRAM region for video engine
Date: Sun, 12 Jul 2026 11:00:08 +0800	[thread overview]
Message-ID: <20260712030011.3778169-6-wens@kernel.org> (raw)
In-Reply-To: <20260712030011.3778169-1-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")
