Currently only the DRM_MODE_REFLECT_Y rotation is supported. The driver already supports reflection on the Y axis via a custom flag which is not very useful because it requires custom userspace. Add the standard rotation property that supports 0 degree rotation and Y axis reflection for primary and overlay planes to provide a better interface than the custom flag. v2: keep custom flag for ABI compatibility (Dmitry) Reviewed-by: Dmitry Osipenko <digetx@gmail.com> Tested-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
