Change in DSI output resolution after boot

Hi
The DSI with 1920*1080-30fps/4lane working well.
But now i need to change output resolution after boot. In attached image, for example hfront-porch = <1007>
When I run " cat /sys/kernel/debug/tegradc.0/mode", It show all params that I show in attached screenshot. But how can I change params now?

Hi,

You can add extra timings inside the dts. DSI does not support hotplug so the modes are pre-defined.
