You can use these from include/video/mipi_display.h:
MIPI_DCS_ENTER_SLEEP_MODE = 0x10, MIPI_DCS_EXIT_SLEEP_MODE = 0x11, MIPI_DCS_ENTER_INVERT_MODE = 0x21, MIPI_DCS_SET_DISPLAY_OFF = 0x28, MIPI_DCS_SET_DISPLAY_ON = 0x29, MIPI_DCS_SET_ADDRESS_MODE = 0x36, MIPI_DCS_SET_PIXEL_FORMAT = 0x3A,
I don't know, that controller cannot do MIPI DSI at all, and we would have to define all the other commands anyway.
