I don't know what MCS is. But DSI is just a bi-directional transfer
protocol between the SoC and the peripheral, you can send arbitrary data
over it.
Normally the SoC composes a pixel stream using overlays and whatnot,
which goes to the DSI hardware, which then serializes the data and sends
it to the peripheral.
But you can as well send any data, like commands, and the peripheral can
respond with any relevant data.
