[PATCH v2 0/4] Add support for Arm Framebuffer Compression(AFBC)

[Ayan Kumar Halder]

In the current series of patches, we are trying to add support for AFBC
modifiers in malidp. AFBC modifiers adds some constraints to framebuffer
size, alignment, pitch, formats, etc. Here we are trying to add support
for one combination of AFBC modifier ie AFBC_FORMAT_MOD_BLOCK_SIZE_16x16 |
AFBC_FORMAT_MOD_SPARSE | AFBC_FORMAT_MOD_YTR.
In future, we intend to add support for more combination of AFBC modifiers.
Currently, we are trying to enable a basic support of AFBC in malidp.

Changes from v2:
- Added ack by Maarten Lankhorst <maarten.lankhorst@xxxxxxxxxxxxxxx>
for patch 1. However, this has been kept in this series in order to help
reviewers review the other patches (which are related to patch 1)
- For patches 2 and 4, replaced DRM_ERROR() with DRM_DEBUG_KMS()
- For patch 3, reworked malidp_de_set_plane_afbc() so as to consolidate
all afbc specific register configuration in this.

Ayan Kumar Halder (4):
  drm/arm/malidp: Add modifier definitions for describing Arm
    Framebuffer Compression (AFBC).
  drm/arm/malidp: Implemented the size validation for AFBC framebuffers
  drm/arm/malidp: Set the AFBC register bits if the framebuffer has AFBC
    modifier
  drm/arm/malidp: Added support for AFBC modifiers for all layers except
    DE_SMART
