We have a MIPI display driven from a dedicated controller/converter which accepts I2C commands and can translate them to/from MIPI DCS commands.

On occasion at power-up the display itself does not always initialise correctly, so I'm looking into checking the state of the MIPI display.

However, the display does not have a detailed data-sheet, and budgets do not allow for joining the MIPI alliance - so I have cribbed a few MIPI-DCS commands from other code found online (eg Linux kernel drivers) etc. but it's not clear how much is universally applicable.

Is there a standard MIPI status register or popular command(s) to find out if a display is "up & working" other than the power/sleep status register?
