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