The hardware doesn't support transposing to 24bpp (RGB888/BGR888) formats. There's no way to advertise this through DRM, so block it from atomic_check instead. Signed-off-by: Dave Stevenson <[email protected]>
…erty Copy the same validation logic as from the plane rotation property. Fixes: 8fec3ff ("drm: Add a rotation parameter to connectors.") Signed-off-by: Dave Stevenson <[email protected]>

Triggered both error cases and confirmed that using the API correctly works as expected. LGTM. |
