Stefan Agner 6e4e3cc46a drm: mxsfb: check framebuffer pitch ... [ Upstream commit d5a0c816900419105a12e7471bf074319dfa34be ] The lcdif IP does not support a framebuffer pitch (stride) other than framebuffer width. Check for equality and reject the framebuffer otherwise. This prevents a distorted picture when using 640x800 and running the Mesa graphics stack. Mesa tries to use a cache aligned stride, which leads at that particular resolution to width != stride. Currently Mesa has no fallback behavior, but rejecting this configuration allows userspace to handle the issue correctly.
