These refinements include using standard mailbox callback interface, timeout detection, and a fixed cmdq_handle. Change in v5: 1. Move mbox_free_channel to a independent patch. Change in v4: 1. Add cmdq_vblank_cnt initial value to 3. 2. Move mtk_drm_cmdq_pkt_create to the same define scope with mtk_drm_cmdq_pkt_destroy. Change in v3: 1. Revert "drm/mediatek: clear pending flag when cmdq packet is done" and add it after the CMDQ refinement patches. 2. Change the remove of struct cmdq_client to remove the pointer of struct cmdq_client. 3. Fix pkt buf alloc once but free many times. Changes in v2: 1. Define mtk_drm_cmdq_pkt_create() and mtk_drm_cmdq_pkt_destroy() when CONFIG_MTK_CMDQ is reachable.
