drm/mediatek: call mtk_dsi_stop() after mtk_drm_crtc_atomic_disable()

2019-06-04T01:54:42+00:00

mtk_dsi_stop() should be called after mtk_drm_crtc_atomic_disable(), which needs ovl irq for drm_crtc_wait_one_vblank(), since after mtk_dsi_stop() is called, ovl irq will be disabled. If drm_crtc_wait_one_vblank() is called after last irq, it will timeout with this message: "vblank wait timed out on crtc 0". This happens sometimes when turning off the screen. In drm_atomic_helper.c#disable_outputs(), the calling sequence when turning off the screen is: 1. mtk_dsi_encoder_disable() --> mtk_output_dsi_disable() --> mtk_dsi_stop(); /* sometimes make vblank timeout in atomic_disable */ --> mtk_dsi_poweroff(); 2. mtk_drm_crtc_atomic_disable() --> drm_crtc_wait_one_vblank(); ... --> mtk_dsi_ddp_stop() --> mtk_dsi_poweroff(); mtk_dsi_poweroff() has reference count design, change to make mtk_dsi_stop() called in mtk_dsi_poweroff() when refcount is 0.

drm/mediatek: clear num_pipes when unbind driver

2019-06-04T01:29:22+00:00

num_pipes is used for mutex created in mtk_drm_crtc_create(). If we don't clear num_pipes count, when rebinding driver, the count will be accumulated. From mtk_disp_mutex_get(), there can only be at most 10 mutex id. Clear this number so it starts from 0 in every rebind. Fixes: 119f5173628a ("drm/mediatek: Add DRM Driver for Mediatek SoC MT8173.")

drm/mediatek: unbind components in mtk_drm_unbind()

2019-06-04T01:28:35+00:00

Unbinding components (i.e. mtk_dsi and mtk_disp_ovl/rdma/color) will trigger master(mtk_drm)'s .unbind(), and currently mtk_drm's unbind won't actually unbind components. During the next bind, mtk_drm_kms_init() is called, and the components are added back. .unbind() should call mtk_drm_kms_deinit() to unbind components. And since component_master_del() in .remove() will trigger .unbind(), which will also unregister device, it's fine to remove original functions called here.
