Check M28EVK (imx28-m28evk.dts), it uses 18bit > LCD and works without this patch I think. Thanks for the pointer. You mentionned in your other mail that it was wired on 24bits but that the screen is actually 18 bits. I went to search for the schematics to look at the wirings to see what could differ, but I couldn't find any for the M28EVK. Are they publicly available?
