Hi,
The imx8mp DSI LCD image appears to be slightly Red and I would like to do some color adjustments to correct HUE.
Any idea how to do that in the driver?
The only promising info I found so far in the RM is pointing to LCDIF (the RM shows that color conversion ALU can be configured via CPU registers) but I am not sure how to set this.
Thank you
Hi Joseph,
Interesting pointer as the questioner has exact same issue.
However the feedback proposal there does not really help unfortunately.
Yes, I think that we can save the part that states that there is a color matrix and we can modify it by writing to the registers you pointed out CSC0_COEF [0..5].
But the register adjustment is up to you, due to you would need to perform the operation to get the value that should be assigned to the Red Value.
Regards
