This is fine, but I had the impression that the patch supports LCDIF1 on mx6(sx|ul) and mx7, not LCDIF2. It looks like I have misunderstood. Can you help me to better understand ? Does it really work with LCDIF2 ? > >> >> But I do not understand how the support for the second LCDIF is >> implemented. I should see that the register set points to LCDIF1 or LCDIF2. Again this is the point I misunderstand.
