From: kyrie wu <kyrie.wu@xxxxxxxxxxxx> 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 order images. Patch 7 add stop cmd function to deal with 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 order images. Patch 14 refactor jpegdec func interface for HW working. Patch 15 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 jpegdec 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 v13: - some modifications for patch v13's review comments. - fix kernel robot check errors. - fix kernel-doc check warns. - fix sparse check warns. - combine jpeg encoder series with decoder series into one single series.
