[PATCH] drm/arm/malidp: Consider rotation memory requirement in case of AFBC framebuffer

From: Ayan Halder
Date: Fri Nov 09 2018 - 05:37:26 EST


Rotation memory for layers is shared with AFBC decoder block. Thus one needs to
calculate rotation memory requirement in case of AFBC framebuffer. This is
used later to verify if it can be sufficed by the hardware rotation memory
availibility.

Fixes: 66da13a ("drm/arm/malidp: Validate rotations for compressed/uncompressed framebuffers for each layer")
