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.


Which pin is the pixel 3 using? Just wanted to know .. is it gpio0 or gpio1?
