[PATCH v7 0/7] Refactor MTK MDP driver into core/components

[Eizan Miyamoto <eizan@chromium.org>]

This is an update to
https://patchwork.kernel.org/project/linux-mediatek/list/?series=283075
To address some comments and fixes.

This series has been verified to work on 5.13.


Changes in v7:
- Drop last two changes from this series related to removing the vpu
  property from the mdp_rdma0 device node

Changes in v6:
- Don't propagate errors from clock_on/off as an afterthought.
- Split apart modifying mdp driver to be loadable from mmsys from
  actually loading it from mmsys into two changs to make review easier.
- Update devicetree bindings to reflect no longer needing the
  mediatek,vpu property in the mdp_rdma0 device node.
- Some stylistic cleanups.

Changes in v5:
- rebase and test on 5.13-next @ e2f74b13dbe6

Changes in v4:
- rebase and test on 5.13
- don't depend on https://patchwork.kernel.org/project/linux-mediatek/list/?series=464873

Changes in v3:
- get mdp master from aliases instead of strcmp against of_node->name

Changes in v2:
- rebased onto Linux 5.12
- 100 char line length allowance was utilized in a few places
- Removal of a redundant dev_err() print at the end of
  mtk_mdp_comp_init()
- Instead of printing errors and ignoring them, I've added a patch to
  correctly propagate them.
- Use of C style comments.
- Three additional patches were added to eliminate dependency on the
  mediatek,vpu property inside the mdp_rdma0 device node.

Eizan Miyamoto (7):
  mtk-mdp: propagate errors from clock_on
  mtk-mdp: add driver to probe mdp components
  mtk-mdp: use pm_runtime in MDP component driver
  media: mtk-mdp: don't pm_run_time_get/put for master comp in clock_on
  mtk-mdp: make mdp driver to be loadable by platform_device_register*()
  soc: mediatek: mmsys: instantiate mdp virtual device from mmsys
  media: mtk-mdp: use mdp-rdma0 alias to point to MDP master
