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 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 | 74 ++++++++++++++++++++---------- 1 file changed, 50 insertions(+), 24 deletions(-)
