[PATCH v2 0/8] drm/msm/dpu: handle non-default TE source pins

[Dmitry Baryshkov <dmitry.baryshkov@linaro.org>]

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.

Changes in v2:
- In DT bindings renamed mdp_gpioN to mdp_vsync_p/_s/_e per pins name (Abhinav)
- Extended bindings to include default: mdp_vsync_p (Rob)
- Renamed dpu_hw_setup_vsync_source() and
  dpu_hw_setup_vsync_source_and_vsync_sel() to match the implementation
  (Abhinav)
- Link to v1: https://lore.kernel.org/r/20240520-dpu-handle-te-signal-v1-0-f273b42a089c@linaro.org
