> This series has been verified to work on 5.13.

The series have also been validated on top of 5.14-rc4 and linux-next
on an Acer Chromebook R 13 without observing any problems and running
some video decoding tests, so, for the full series.

> 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.
