Subject[V11,0/7] Enable two hardware jpeg encoder for MT8195
From: kyrie wu <>

This series has been tested with MT8195 Gstreamer.
Encoding worked for this chip.

Patches 1 Adds jpeg encoder dt-bindings for mt8195

Patches 2 jpeg encoder builds two module for using Multi-HW,
export some functions to make them visible by other modules.

Patches 3 use devm_of_platform_populate to manage multi-hardware.

Patch 4 add jpeg encoding timeout function to judge hardware timeout.

Patch 5 add encoding work queue to deal with multi-hardware encoding
at the same time.

Patch 6 add output picture reorder function to order images.

Patch 7 add stop cmd function to deal with EOS operation.
This series patches dependent on:
media_stage tree:

patch1 new jpegenc dt-bindings included files
[2] MM IOMMU binding:

[3] MT8195 power domain:

Changes compared with v10:
- some modifications for patch v10's review comments.
- fix Gstreamer test errors.

Changes compared with v9:
- some modifications for patch v9's review comments.

Changes compared with v8:
- some modifications for patch v8's review comments.
- add stop cmd function.

Changes compared with v7:
- some modifications for patch v6's review comments.

Changes compared with v6:
- new yaml file for mt8195 jpeg encoder.
- some modifications for patch v5's review comments.

Changes compared with v5:
- use of_platform_populate to replace component framework to
manage multi-hardware in patch 2.

Changes compared with v4:
- No change compaered with v4

Changes compared with v3:
- Structure patches for consistency, non-backward
compatible and do not break any existing functionality

Changes compared with v2:
- Split the last two patches into several patches
to enhance readability
- Correct some syntax errors
- Explain why the component framework is used

Changes compared with v1:
- Add jpeg encoder dt-bindings for MT8195
- Use component framework to manage jpegenc HW
- Add jpegenc output pic reorder function interface

kyrie wu (7):
dt-bindings: mediatek: Add mediatek, mt8195-jpgenc compatible
mtk-jpegenc: export jpeg encoder functions
mtk-jpegenc: manage jpegenc multi-hardware
mtk-jpegenc: add jpegenc timeout func interface
mtk-jpegenc: add jpeg encode worker interface
mtk-jpegenc: add output pic reorder interface
mtk-jpegenc: add stop cmd interface for jpgenc
