[PATCH v8 00/16] introduce more MDP3 components in MT8195

[Moudy Ho]

Changes since v7:
- Rebase on linux-next.
- Dependent dtsi files:
  https://patchwork.kernel.org/project/linux-mediatek/list/?series=797543
- Depends on:
  Message ID = 20231024130048.14749-9-shawn.sung@mediatek.com
- Correct the bindings of the four components: FG, TCC, TDSHP and HDR.
  The names of the first three are expanded in the title, and
  the descriptions of all four have been enhanced.

Changes since v6:
- Rebase on v6.6-rc5.
- Dependent dtsi files:
  https://patchwork.kernel.org/project/linux-mediatek/list/?series=792079
- Depends on:
  Message ID = 20231006073831.10402-5-shawn.sung@mediatek.com
- Discard splitting RDMA's common properties and instead use 'allOf' to
  isolate different platform features.
- Revise the incorrect properties in FG, HDR, STITCH, TCC and TDAP bindings.
- Adding SoC-specific compatible string to components, like WROT and RSZ,
  that are inherited from MT8183.
- Fixed typos in TCC patch and enhancing its hardware description.

Changes since v5:
- Rebase on v6.6-rc2.
- Dependent dtsi files:
  https://patchwork.kernel.org/project/linux-mediatek/list/?series=786511
- Depends on:
  Message ID = 20230911074233.31556-5-shawn.sung@mediatek.com
- Split out common propertis for RDMA.
- Split each component into independent patches.

Changes since v4:
- Rebase on v6.6-rc1
- Organize identical hardware components into their respective files.

Hi,

The purpose of this patch is to separate the MDP3-related bindings from
the original mailing list mentioned below:
https://lore.kernel.org/all/20230208092209.19472-1-moudy.ho@mediatek.com/
Those binding files describe additional components that
are present in the mt8195.

[PATCH v8 01/16] dt-bindings: media: mediatek: mdp3: correct RDMA and WROT node with generic names

[Moudy Ho]

The DMA-related nodes RDMA/WROT in MDP3 should be changed to generic names.
In addition, fix improper space indent in example.

[PATCH v8 02/16] dt-bindings: media: mediatek: mdp3: merge the indentical RDMA under display

[Moudy Ho]

To simplify maintenance and avoid branches, the identical component
should be merged and placed in the path belonging to the MDP
(from display/* to media/*).

In addition, currently only MDP utilizes RDMA through CMDQ, and the
necessary properties for "mediatek,gce-events", and "mboxes" have been
set up for this purpose.
Within DISP, it directly receives component interrupt signals.

'maxItems: 1' here.

The same thing applies to mboxes.

Following the prior comments, add these entries to the top-level 
'mboxes' and then here just put 'minItems: 5'.

Hi Rob,

Thanks for assisting with the review and suggesting an improved method
in patch [2/16] and here for bounding related item quantites.

I have a question regarding the current item description. It seems to
imply a specific order. If the order of the description is different
for any reason, should it be fully re-listed under 'allOf'?

Sincerely,
Moudy

The compatible name of the mt8188 display padding, on which this patch
depends, has been changed in v11. Please disregard the typo here. it
will be updated in the next version as soon as possible.

Thanks,
Moudy

Hi Robe,

I apologize for not noticing the changes in the dependent patch and
failing to update one compatible name. I will remove the ACK tage and
would appreciate your help in reviewing it again in the next version.
