This commit is based on 20231024130048.14749-1-shawn.sung@xxxxxxxxxxxx. This bug was found when running IGT tests. For CRTCs that doesn't support rotation should still return DRM_MODE_ROTATE_0, otherwise the test will fail to restart. Returns the hardware capabilities accordingly. Changes in v4: - Remove rotation property from the driver data since OVL rotation property for all chips are the same Changes in v3: - Return 0 (not support) if rotation capabilities is not defined in the driver data. Changes in v2: - Restore DRM_MODE_ROTATE_180 (reflect x + reflect y = rotate 180) - Define supported rotations in the driver data Hsiao Chien Sung (1): drm/mediatek: Fix errors when reporting rotation capability drivers/gpu/drm/mediatek/mtk_disp_drv.h | 1 + drivers/gpu/drm/mediatek/mtk_disp_ovl.c | 18 ++++++------------ .../gpu/drm/mediatek/mtk_disp_ovl_adaptor.c | 9 +++++++++ drivers/gpu/drm/mediatek/mtk_drm_ddp_comp.c | 1 + drivers/gpu/drm/mediatek/mtk_drm_plane.c | 2 +- 5 files changed, 18 insertions(+), 13 deletions(-) -- 2.39.2
