drm/mediatek: Fix cursor plane no update

2021-08-18T07:06:52Z

[ Upstream commit 1a64a7aff8da352c9419de3d5c34343682916411 ] 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.

drm/mediatek: Fix PM reference leak in mtk_crtc_ddp_hw_init()

2021-07-19T08:04:31Z

[ Upstream commit 69777e6ca396f0a7e1baff40fcad4a9d3d445b7a ] pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. Fix it by replacing it with pm_runtime_resume_and_get to keep usage counter balanced. Reported-by: Hulk Robot Signed-off-by: Wang Li Signed-off-by: Chun-Kuang Hu Signed-off-by: Sasha Levin

drm/mediatek: Don't support hdmi connector creation

2021-04-01T14:05:20Z

commit f01195148967 ("drm/mediatek: mtk_dpi: Create connector for bridges") broke the display support for elm device since mtk_dpi calls drm_bridge_attach with the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR while mtk_hdmi does not yet support this flag. Fix this by accepting DRM_BRIDGE_ATTACH_NO_CONNECTOR in bridge attachment. Implement the drm_bridge_funcs .detect() and .get_edid() operations, and call drm_bridge_hpd_notify() to report HPD. This provides the necessary API to support disabling connector creation. In addition, the field 'conn' is removed from the mtk_hdmi struct since mtk_hdmi don't create a connector. It is replaced with a pointer 'curr_conn' that points to the current connector which can be access through the global state. This patch is inspired by a similar patch for bridge/synopsys/dw-hdmi.c: commit ec971aaa6775 ("drm: bridge: dw-hdmi: Make connector creation optional") But with the difference that in mtk-hdmi only the option of not creating a connector is supported.

drm/mediatek: Switch the hdmi bridge ops to the atomic versions

2021-04-01T13:57:30Z

The bridge operation '.enable' and the audio cb '.get_eld' access hdmi->conn. In the future we will want to support the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR and then we will not have direct access to the connector. The atomic version '.atomic_enable' allows accessing the current connector from the state. This patch switches the bridge to the atomic version to prepare access to the connector in later patches.
