The DSI generic binding asks that peripherals that are controlled<br>
through a DCS be a subnode of the MIPI-DSI bus, not through a port<br>
endpoint.<br></blockquote><div> Our DSI controller don't support DCS now...</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
