drm/mediatek: Add component_del in OVL and COLOR remove function

2021-08-11T23:00:50+00:00

Add component_del in OVL and COLOR remove function. Fixes: ff1395609e20 ("drm/mediatek: Move mtk_ddp_comp_init() from sub driver to DRM driver") Signed-off-by: jason-jh.lin Signed-off-by: Chun-Kuang Hu

drm/mediatek: Add AAL output size configuration

2021-08-11T22:43:28+00:00

To avoid the output width and height is incorrect, AAL_OUTPUT_SIZE configuration should be set. Fixes: 0664d1392c26 ("drm/mediatek: Add AAL engine basic function") Signed-off-by: jason-jh.lin Signed-off-by: Chun-Kuang Hu

drm/mediatek: Fix cursor plane no update

2021-07-22T14:57:52+00:00

The cursor plane should use the current plane state in atomic_async_update because it would not be the new plane state in the global atomic state since _swap_state happened when those hook are run. Fix cursor plane issue by below modification: 1. Remove plane_helper_funcs->atomic_update(plane, state) in mtk_drm_crtc_async_update. 2. Add mtk_drm_update_new_state in to mtk_plane_atomic_async_update to update the cursor plane by current plane state hook and update others plane by the new_state. Fixes: 37418bf14c13 ("drm: Use state helper instead of the plane state pointer") Signed-off-by: jason-jh.lin Tested-by: Enric Balletbo i Serra Signed-off-by: Chun-Kuang Hu

drm/mediatek: mtk-dpi: Set out_fmt from config if not the last bridge

2021-07-22T14:44:42+00:00

atomic_get_output_bus_fmts() is only called when the bridge is the last element in the bridge chain. If mtk-dpi is not the last bridge, the format of output_bus_cfg is MEDIA_BUS_FMT_FIXED, and mtk_dpi_dual_edge() will fail to write correct value to regs.

drm/mediatek: dpi: Fix NULL dereference in mtk_dpi_bridge_atomic_check

2021-07-22T00:28:34+00:00

bridge->driver_private is not set (NULL) so use bridge_to_dpi(bridge) like it's done in bridge_atomic_get_output_bus_fmts Fixes: ec8747c52434 ("drm/mediatek: dpi: Add bus format negotiation") Signed-off-by: Frank Wunderlich Tested-by: Hsin-Yi Wang Signed-off-by: Chun-Kuang Hu

Mediatek DRM Next for Linux 5.14 1. Add MT8167 HDMI support 2. Fix PM reference leak 3. Add MT8183 DPI dual edge support Signed-off-by: Dave Airlie From: Chun-Kuang Hu Link: https://patchwork.freedesktop.org/patch/msgid/20210616150301.292-1-chunkuang.hu@kernel.org

drm/mediatek: dpi: Add bus format negotiation

2021-06-04T00:58:56+00:00

Add the atomic_get_output_bus_fmts, atomic_get_input_bus_fmts to negotiate the possible output and input formats for the current mode and monitor, and use the negotiated formats in a basic atomic_check callback. Signed-off-by: Jitao Shi Signed-off-by: Rex-BC Chen Signed-off-by: Chun-Kuang Hu

drm/mediatek: dpi: Add output bus formats to driver data

2021-06-04T00:24:55+00:00

For each SoC, dpi support different output bus formats, so add these information into driver data. Signed-off-by: Jitao Shi Signed-off-by: Rex-BC Chen Signed-off-by: Chun-Kuang Hu

drm/mediatek: dpi: Add dual edge sample mode support

2021-06-04T00:23:01+00:00

To support RGB888_2X12_LE and RGB888_2X12_BE, dpi should sample on dual edge which could recude half data io pins. For RGB888_1X24, dpi just sample on single edge (rising or falling edge). Signed-off-by: Jitao Shi Signed-off-by: Rex-BC Chen Signed-off-by: Chun-Kuang Hu
