Subject: [V11,0/7] Enable two hardware jpeg encoder for MT8195

From: kyrie wu <kyrie.wu@...iatek.com>

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.

  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
