This series adds support for multi hardwares jpeg enc & dec,
by first adding use of_platform_populate to manage each hardware
information:interrupt, clock, register bases and power.
Secondly add jpeg enc & dec work queue to deal with the encoding
or decoding requests of multi-hardwares at the same time.
Lastly, add output picture reorder function interface to
eliminate the out of order images.

This series has been tested with MT8195 Gstreamer.
Encoding and decoding 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 jpgenc order images.

Patch 7 add stop cmd function to deal with jpgenc EOS operation.

Patch 8 Adds jpeg decoder dt-bindings for mt8195

Patches 9 jpeg decoder builds three module for using Multi-HW,
export some functions to make them visible by other modules.

Patch 10 use of_platform_populate to manage multi-hardware.

Patch 11 add jpeg decoding timeout function to judge hardware timeout.

Patch 12 add decoding work queue to deal with multi-hardware decoding
at the same time.

Patch 13 add output picture reorder function to jpgdec order images.

Patch 14 refactor jpegdec func interface for HW working.

Patch 15 add stop cmd function to deal with jpgdec EOS operation.
