[RFC AFBC 11/12] drm/arm/malidp:- Disregard the pitch alignment constraint for AFBC framebuffer.

2018-12-03 Thread Ayan Halder
Considering the fact that some of the AFBC specific pixel formats are expressed in bits per pixel (ie bpp which is not byte aligned), the pitch (ie width * bpp) is not guaranteed to be aligned to burst size (ie 8 or 16 bytes). For example, DRM_FORMAT_VUY101010 is 30 bits per pixel. For a
