It is a MIPI DSI video mode panel. The panel seems to use a Sitronix ST7703 look alike (most of the commands look similar to the ST7703's data sheet but use a different number of parameters). The initial version of the DSI init sequence (including sleeps) were provided by the vendor. Sleeps were reduced considerably though to speed up initialization.
