Subject: [PATCH 6/7] arm64: dts: allwinner: sun50i-h6: Add missing IOMMU for video engine
Date: Tue,  5 May 2026 21:48:10 +0800	[thread overview]
Message-ID: <20260505134812.408316-7-wens@kernel.org> (raw)
In-Reply-To: <20260505134812.408316-1-wens@kernel.org>

The video engine on the H6 actually has two IOMMU ports. The one already
listed is simply named "VE" in the user manual. The missing one is named
"VE_R" and is probably either read-only or used for reference frames.
Either way, it should be listed.

Add a reference to the "VE_R" IOMMU port to the video engine node.

Fixes: 62a8ccf3a248 ("arm64: dts: allwinner: h6: Fix Cedrus IOMMU usage")
