I am trying to connect MIPI DSI display to VC4 but it isn't showing anything. I have noticed that the DSI host  transfer() method vc4_dsi_host_transfer gets called for the commands that I am sending from my panel driver, but not for pixel data. My question: are pixel data normally transferred the same method within vc4_dsi driver or any "behind the scene" way ?

My question: are pixel data normally transferred the same method within vc4_dsi driver
