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.
