From: kyrie wu <kyrie.wu@mediatek.com> This series adds support for multi hardware jpeg encoding, by first adding use of_platform_populate to manage each hardware information: interrupt, clock, register bases and power. Secondly add encoding work queue to deal with the encoding requestsof multi-hardware 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 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@mediatek.com/ [3] MT8195 power domain: https://patchwork.kernel.org/project/linux-mediatek/list/?series=580579 Changes compared with v9: - some modifications for patch v9's review comments.
