The MT8183 display serial interface (DSI) is based on MIPI
Alliance Specification, supporting high-speed serial data
transfer between host processor and peripheral devices such
as display modules.
DSI supports both video mode and command mode data transfer
defined in MIPI spec, and it also provides bidirectional
transmission with low-power mode to receive messages from
the peripheral.
