Add support for MDP5 version v3.0 found on msm8998. Signed-off-by: Jeffrey Hugo <jeffrey.l.hugo@gmail.com> --- 8998 support could probably be MDP5 or DPU. This MDP5 support works, but may not support all of the features that 8998 supports. However, DPU seems to only support 845 (MDP v4.0) with fundamental assumptions about the base level a features supported, some of which 8998 does not infact support, so DPU would likely need significant re-writes to support 8998. I'm not sure the effort is worth it since MDP5 needs so little effort to support 8998. drivers/gpu/drm/msm/disp/mdp5/mdp5_cfg.c | 132 ++++++++++++++++++++++- 1 file changed, 128 insertions(+), 4 deletions(-)
