We'll want to keep the EDID immutable while parsing. Stop modifying the EDID because of the quirks. In theory, this does have userspace implications, but the userspace is supposed to use the modes exposed via KMS API, not by parsing the EDID directly.

On devices with DMM, all allocations are done through either DMM or TILER. DMM/TILER being a limited resource means that such allocations will start to fail before actual free memory is exhausted. What is even worse is that with time DMM/TILER space gets fragmented to the point that even if we have enough free DMM/TILER space and free memory, allocation fails because there is no big enough free block in DMM/TILER space. Such failures can be easily observed with OMAP xorg DDX, for example - starting few GUI applications (so buffers for their windows are allocated) and then rotating landscape<->portrait while closing and opening new windows soon results in allocation failures. Fix that by mapping buffers through DMM/TILER only when really needed, like, for scanout buffers.

Currently code allocates non-scanout BOs from SHMEM and those objects are accessible to userspace by mmap(). However, on devices with no DMM (like OMAP3), the same objects are not accessible by kernel drivers that want to render to them as code refuses to export them. In turn this means that on devices with no DMM, all buffers must be allocated as scanout, otherwise only CPU can access them. On those devices, scanout buffers are allocated from CMA, making those allocations highly unreliable. Fix that by implementing functionality to export SHMEM backed buffers on devices with no DMM. This makes CMA memory only being used when needed, instead for every buffer that has to be off-CPU rendered.

Currently we take the max_bpc property as the bpc value and do not try anything else. However, what the other drivers seem to be doing is that they would try with the highest bpc allowed by the max_bpc property and the hardware capabilities, test if it results in an acceptable configuration, and if not decrease the bpc and try again.
