From: kyrie wu <kyrie.wu@xxxxxxxxxxxx> 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: [1] https://git.linuxtv.org/media_stage.git/commit/?id=b3627647f9ea7473d10fb08a95fd7c4133a17ca4 patch1 new jpegenc dt-bindings included files [2] MM IOMMU binding: https://patchwork.kernel.org/project/linux-mediatek/patch/20220217113453.13658-2-yong.wu@xxxxxxxxxxxx/ [3] MT8195 power domain: https://patchwork.kernel.org/project/linux-mediatek/list/?series=580579 Changes compared with v10: - some modifications for patch v10's review comments. - fix Gstreamer test errors.
