In the last couple days I modified the mxsfb.c driver code for the iMX7 to be able to use a LCD display with 8bit serial interface (only 8bits at a time, but three times the speed).
It works so far, but I only get 6bits per color out of the interface. Two bits are always 0, even with Test Images with FF as data. No shifting is active.
Any idea where I could look for the reason?
And one other question. The lcdif driver is one of many that references older imx ICs. In this case imx23 or imx28. Is ther an overview anywhere which compatibilities there are?
Thanks and best regards,
