drm/mediatek: reduce clear event

2020-10-29T09:08:15+00:00

[ Upstream commit bee1abc9cc021f50b90f22a589d9ddc816a80db0 ] No need to clear event again since event always clear before wait. This fix depend on patch: "soc: mediatek: cmdq: add clear option in cmdq_pkt_wfe api" Fixes: 2f965be7f9008 ("drm/mediatek: apply CMDQ control flow") Signed-off-by: Dennis YC Hsieh Reviewed-by: Bibby Hsieh Acked-by: Chun-Kuang Hu Link: https://lore.kernel.org/r/1594136714-11650-10-git-send-email-dennis-yc.hsieh@mediatek.com Signed-off-by: Matthias Brugger Signed-off-by: Sasha Levin

drm/mediatek: Add missing put_device() call in mtk_hdmi_dt_parse_pdata()

2020-09-23T10:59:57+00:00

[ Upstream commit 0680a622318b8d657323b94082f4b9a44038dfee ] if of_find_device_by_node() succeed, mtk_drm_kms_init() doesn't have a corresponding put_device(). Thus add jump target to fix the exception handling for this function implementation.

drm/mediatek: Add exception handing in mtk_drm_probe() if component init fail

2020-09-23T10:59:57+00:00

[ Upstream commit 64c194c00789889b0f9454f583712f079ba414ee ] mtk_ddp_comp_init() is called in a loop in mtk_drm_probe(), if it fail, previous successive init component is not proccessed. Thus uninitialize valid component and put their device if component init failed. Fixes: 119f5173628a ("drm/mediatek: Add DRM Driver for Mediatek SoC MT8173.")

[ Upstream commit f85acdad07fe36b91f2244263a890bf372528326 ] Even though cmdq client is created successfully, without the cmdq event, cmdq could not work correctly, so use CPU when fail to get cmdq event.
