IMX8P MIPI DSI LCD RGB gain configuration in Display driver

[malik_cisse]

Hello,

I am using a MIPI DSI LCD module with the HX8369A chip as a controller.
I want to calibrate the LCD colors and adjust the gain values of individual RGB color components.
These settings cannot be adjusted directly in the LCD controller (HX8369A), so I would like to make these adjustments before the LCD (e.g in LCDIF, DRM driver etc.).
Unfortunately, I have no clue about how to control this. Do you have any idea on how to change the RGB colors in the display driver? An example would be appreciated.

Thx

In the ref manual they do mention a color palette.
Could this be used?

There is no such register to set gain configuration in i.MX8MP
