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.
MIPI DCS commands can be sent over both Display Serial Interface (DSI)
and in your case Display Bus Interface (DBI) (not quite sure if the
Control Interface can be outside of DBI). So Display Command Set (DCS)
is not specific to the interface, but to the controller.
It's up to you if you want to use them though.
Noralf.
