[PATCHv2,0/4] AFBC support for Rockchip

Message

Andrzej Pietrasiewicz Nov. 4, 2019, 10:12 p.m. UTC

This series adds AFBC support for Rockchip. It is inspired by:

https://chromium.googlesource.com/chromiumos/third_party/kernel/+/refs/heads/factory-gru-9017.B-chromeos-4.4/drivers/gpu/drm/rockchip/rockchip_drm_vop.c

The first patch factors out some afbc helper functions, as they are useful
in general. The second and third patches use the helpers and the fourth patch
adds implementation proper of AFBC support for Rockchip.

v1..v2:

- addressed comments from Daniel Stone, Ayan Halder, Mihail Atanassov
- coding style fixes

Andrzej Pietrasiewicz (4):
  drm/arm: Factor out generic afbc helpers
  drm/malidp: use afbc helpers
  drm/komeda: use afbc helpers
  drm/rockchip: Add support for afbc
