The lcdif IP does not support a framebuffer pitch (stride) other than the CRTC width.
This may be true for some SOCs, but not for all of them. I used to have this working flawlessly on the imx8mq like so: http://projects.dpa.li/git/?p=linux.git;a=commitdiff;h=5a7baa8ba7f1f30139cfcd0f9e13b3773f3605ff That in turn was based on some patches which weren't fully upstreamed yet at the time, and was inspired by another patch I had seen here: https://lore.kernel.org/linux-arm-kernel/20190722174853.GA31795@bogus/t/#m7ac218480eb1d827ff65f82f2e03a5a84c94a5e0 I had almost forgotten about this already, since I currently don't need it anymore, and I was waiting for the patches it was based on to get taken up. But if anyone else needs this, feel free to do whatever you want with it. I could also take another look at this and submit some patches if this is preferred, but I'm quiet busy right now, so that could take a while. In the meantime and for other SOCs, I think checking for an unsupported pitch is still needed regardless. I'm not against this patch, this is just a note to make sure it's known that and how this can be done on the imx8mq.
