In order to ensure the timing of dsi_power_on/off and the timing of pulling up/down the MIPI signal, the modification of v5.9 is synchronized in this series of patches. Changes since v3: 1. Rebase kernel-5.18-rc1. 2. Added dsi_enable protection. 3. Encapsulates the dsi_lane_ready function. Changes since v2: 1. Rebase linux-next. Changes since v1: 1. Dsi sequence marked with patch adjustment. 2. Fixes: mtk_dsi: Use the drm_panel_bridge. Jitao Shi (3): drm/mediatek: Adjust the timing of mipi signal from LP00 to LP11 drm/mediatek: Separate poweron/poweroff from enable/disable and define new funcs drm/mediatek: keep dsi as LP00 before dcs cmds transfer Xinlei Lee (1): drm/mediatek: Add pull-down MIPI operation in mtk_dsi_poweroff function drivers/gpu/drm/mediatek/mtk_dsi.c | 81 ++++++++++++++++++++---------- 1 file changed, 55 insertions(+), 26 deletions(-)
