Message

Eizan Miyamoto July 9, 2021, 2:23 a.m. UTC

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 v5:
- rebase and build-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 (8):
  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: soc: mediatek: register mdp from mmsys
  media: mtk-mdp: search for vpu node instead of linking it to a
    property
  media: mtk-mdp: propagate errors better in pm_suspend/resume
  media: mtk-mdp: use mdp-rdma0 alias to point to MDP master
  dts: mtk-mdp: remove mediatek,vpu property from primary MDP device
