Subject: [PATCH v2 2/3] drm/rockchip: vop2: Skip UV plane setup for packed YUV formats
Date: Thu, 29 Oct 2026 16:14:28 +0800	[thread overview]
Message-ID: <20261029081429.862-3-kernel@airkyi.com> (raw)
In-Reply-To: <20261029081429.862-1-kernel@airkyi.com>

From: Chaoyi Chen <chaoyi.chen@rock-chips.com>

Packed YUV formats store chroma interleaved with luma in the same plane,
so they have no plane 1 that the UV address registers could point at.

Restrict both the plane 1 offset calculation and the UV register writes
to formats with more than one plane.
