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 both MT8195. Encoding worked for this chip. Patches 1~2 use of_platform_populate to replace component framework to manage multi-hardware. Patch 3 add jpeg encoding timeout function to judge hardware timeout. Patch 4 add encoding work queue to deal with multi-hardware encoding at the same time. Patch 5 add output picture reorder function to order images. --- Changes compared with v5: - use of_platform_populate to replace component framework to manage multi-hardware in patch 2. Changes compared with v4: --No change compaered with v4 Changes compared with v3: --Structure patches for consistency, non-backward compatible and do not break any existing functionality Changes compared with v2: --Split the last two patches into several patches to enhance readability --Correct some syntax errors --Explain why the component framework is used Changes compared with v1: --Add jpeg encoder dt-bindings for MT8195 --Use component framework to manage jpegenc HW --Add jpegenc output pic reorder function interface kyrie.wu (5): dt-bindings: mediatek: Add mediatek, mt8195-jpgenc compatible media: mtk-jpegenc: manage jpegenc multi-hardware media: mtk-jpegenc: add jpegenc timeout func interface media: mtk-jpegenc: add jpeg encode worker interface media: mtk-jpegenc: add output pic reorder interface .../bindings/media/mediatek-jpeg-encoder.yaml | 3 + drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c | 287 +++++++++++++++---- drivers/media/platform/mtk-jpeg/mtk_jpeg_core.h | 91 +++++- drivers/media/platform/mtk-jpeg/mtk_jpeg_dec_hw.c | 1 + drivers/media/platform/mtk-jpeg/mtk_jpeg_dec_hw.h | 3 +- drivers/media/platform/mtk-jpeg/mtk_jpeg_enc_hw.c | 316 ++++++++++++++++++++- 6 files changed, 644 insertions(+), 57 deletions(-)
