Command-mode DSI panels need to signal the display controlller when
vsync happens, so that the device can start sending the next frame. Some
devices (Google Pixel 3) use a non-default pin, so additional
configuration is required. Add a way to specify this information in DT
and handle it in the DSI and DPU drivers.

Dmitry Baryshkov (7):
dt-bindings: display/msm/dsi: allow specifying TE source
drm/msm/dpu: convert vsync source defines to the enum
drm/msm/dsi: drop unused GPIOs handling
drm/msm/dpu: pull the is_cmd_mode out of _dpu_encoder_update_vsync_source()
drm/msm/dpu: rework vsync_source handling
drm/msm/dsi: parse vsync source from device tree
drm/msm/dpu: support setting the TE source
