drm/imx: ipuv3-plane: fix YUV framebuffer scanout on the base plane (5be5dd38) · Commits · 戴 / test

Historically, only RGB framebuffers could be assigned to the primary plane. This changed with universal plane support. Since no colorspace conversion was set up for the IPUv3 full plane, assigning YUV frame buffers to the primary plane caused incorrect output. Fix this by enabling color space conversion also for the primary plane. Signed-off-by:
