[PATCH v3] drm: mxsfb: check framebuffer pitch

2020-09-08 Thread Stefan Agner
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
