This patchset introduces drm private object in KMS to manage HW
resource management. It modifies the resource manager by
introducing API's to do per DRM object resource allocation/cleanups.

The patchset is based on: https://patchwork.kernel.org/patch/10461375/

major changes in v2:
    - Fix return values in kms (Jordan)
    - Split irrelevant changes from master patch
      into separate patches (Sean)

Jeykumar Sankaran (14):
  drm/msm/dpu: remove scalar config definitions
  drm/msm/dpu: remove resource pool manager
  drm/msm/dpu: remove ping pong split topology variables
  drm/msm/dpu: program master-slave encoders explicitly
  drm/msm/dpu: use kms stored hw mdp block
  drm/msm/dpu: remove stale encoder code
  drm/msm/dpu: iterate for assigned hw ctl in virtual encoder
  drm/msm/dpu: avoid querying for hw intf before assignment
  drm/msm/dpu: move hw resource tracking to crtc state
  drm/msm/dpu: rename hw_ctl to lm_ctl
  drm/msm/dpu: remove topology name
  drm/msm/dpu: remove display H_TILE from encoder
  drm/msm/dpu: add atomic private object to dpu kms
  drm/msm/dpu: use private obj to track hw resources
