Subject: drm/imx: ipuv3-plane: fix planar YUV 4:2:0 support
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6ac217eef5d46fe9e3d6f85ea2e303422615a18c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/imx: ipuv3-plane: fix planar YUV 4:2:0 support

The driver already advertises multi-planar YUV support, but
previously the U/V offset and stride setup was missing.
