This series adds support for multi hardware decode into mtk-vcodec, by first adding component framework to manage each hardware information: interrupt, clock, register bases and power. Secondly add core thread to deal with core hardware message, at the same time, add msg queue for different hardware share messages. Lastly, the architecture of different specs are not the same, using specs type to separate them. This series has been tested with both MT8183 and MT8173. Decoding was working for both chips. Patches 1~3 rewrite get register bases and power on/off interface. Patch 4 add component framework to support multi hardware. Patch 5 separate video encoder and decoder document Patches 6-15 add interfaces to support core hardware. ---- This patch dependents on : "media: mtk-vcodec: support for MT8183 decoder"[1] and "Mediatek MT8192 clock support"[2]. 1: Multi hardware decode is based on stateless decoder, MT8183 is the first time to add stateless decoder. Otherwise it will cause conflict. This patch will be accepted in 5.15[1]. 2: The definition of decoder clocks are in mt8192-clk.h, this patch already in clk tree[2].

Add prameter in pdata, for all platform will use compoent after mt8183 >> + if (dev->is_comp_supported) { >> + ret = mtk_vcodec_init_master(dev); >> + if (ret < 0) >> + goto err_component_match; >> + } else { >> + platform_set_drvdata(pdev, dev); >> + } > + Has asked the same question in [1]. Why it removes the > +platform_set_drvdata() above? mtk_vcodec_init_master() also calls platform_set_drvdata(). Must call component_master_add_with_match after platform_set_drvdata for component architecture. - Fix yaml files check fail for patch 5/15 - Fix yaml file check fail for patch 14/15 Changes compared with v1: - Fix many comments for patch 3/14 - Remove unnecessary code for patch 4/14 - Using enum mtk_vdec_hw_count instead of magic numbers for patch 6/14 - Reconstructed get/put lat buffer for lat and core hardware for patch 7/14 - Using yaml format to instead of txt file for patch 12/14 Yunfei Dong (15): media: mtk-vcodec: Get numbers of register bases from DT media: mtk-vcodec: Align vcodec wake up interrupt interface media: mtk-vcodec: Refactor vcodec pm interface media: mtk-vcodec: Use component framework to manage each hardware information dt-bindings: media: mtk-vcodec: Separate video encoder and decoder dt-bindings media: mtk-vcodec: Use pure single core for MT8183 media: mtk-vcodec: Add irq interface for multi hardware media: mtk-vcodec: Add msg queue feature for lat and core architecture media: mtk-vcodec: Generalize power and clock on/off interfaces media: mtk-vcodec: Add new interface to lock different hardware media: mtk-vcodec: Add core thread media: mtk-vcodec: Support 34bits dma address for vdec dt-bindings: media: mtk-vcodec: Adds decoder dt-bindings for mt8192 media: mtk-vcodec: Add core dec and dec end ipi msg media: mtk-vcodec: Use codec type to separate different hardware .../media/mediatek,vcodec-comp-decoder.yaml | 192 ++++++++++++ .../media/mediatek,vcodec-decoder.yaml | 175 +++++++++++ .../media/mediatek,vcodec-encoder.yaml | 185 +++++++++++ .../bindings/media/mediatek-vcodec.txt | 130 -------- drivers/media/platform/mtk-vcodec/Makefile | 2 + .../platform/mtk-vcodec/mtk_vcodec_dec.c | 4 +- .../platform/mtk-vcodec/mtk_vcodec_dec.h | 1 + .../platform/mtk-vcodec/mtk_vcodec_dec_drv.c | 276 ++++++++++++++--- .../platform/mtk-vcodec/mtk_vcodec_dec_hw.c | 184 +++++++++++ .../platform/mtk-vcodec/mtk_vcodec_dec_hw.h | 53 ++++ .../platform/mtk-vcodec/mtk_vcodec_dec_pm.c | 98 ++++-- .../platform/mtk-vcodec/mtk_vcodec_dec_pm.h | 13 +- .../mtk-vcodec/mtk_vcodec_dec_stateful.c | 2 + .../mtk-vcodec/mtk_vcodec_dec_stateless.c | 2 + .../platform/mtk-vcodec/mtk_vcodec_drv.h | 71 ++++- .../platform/mtk-vcodec/mtk_vcodec_enc_drv.c | 12 +- .../platform/mtk-vcodec/mtk_vcodec_enc_pm.c | 1 - .../platform/mtk-vcodec/mtk_vcodec_intr.c | 27 +- .../platform/mtk-vcodec/mtk_vcodec_intr.h | 4 +- .../platform/mtk-vcodec/mtk_vcodec_util.c | 87 +++++- .../platform/mtk-vcodec/mtk_vcodec_util.h | 8 +- .../platform/mtk-vcodec/vdec/vdec_h264_if.c | 2 +- .../mtk-vcodec/vdec/vdec_h264_req_if.c | 2 +- .../platform/mtk-vcodec/vdec/vdec_vp8_if.c | 2 +- .../platform/mtk-vcodec/vdec/vdec_vp9_if.c | 2 +- .../media/platform/mtk-vcodec/vdec_drv_if.c | 21 +- .../media/platform/mtk-vcodec/vdec_ipi_msg.h | 16 +- .../platform/mtk-vcodec/vdec_msg_queue.c | 290 ++++++++++++++++++ .../platform/mtk-vcodec/vdec_msg_queue.h | 157 ++++++++++ .../media/platform/mtk-vcodec/vdec_vpu_if.c | 46 ++- .../media/platform/mtk-vcodec/vdec_vpu_if.h | 22 ++ .../platform/mtk-vcodec/venc/venc_h264_if.c | 2 +- .../platform/mtk-vcodec/venc/venc_vp8_if.c | 2 +- 33 files changed, 1812 insertions(+), 279 deletions(-) create mode 100644 Documentation/devicetree/bindings/media/mediatek,vcodec-comp-decoder.yaml create mode 100644 Documentation/devicetree/bindings/media/mediatek,vcodec-decoder.yaml create mode 100644 Documentation/devicetree/bindings/media/mediatek,vcodec-encoder.yaml delete mode 100644 Documentation/devicetree/bindings/media/mediatek-vcodec.txt create mode 100644 drivers/media/platform/mtk-vcodec/mtk_vcodec_dec_hw.c create mode 100644 drivers/media/platform/mtk-vcodec/mtk_vcodec_dec_hw.h create mode 100644 drivers/media/platform/mtk-vcodec/vdec_msg_queue.c create mode 100644 drivers/media/platform/mtk-vcodec/vdec_msg_queue.h -- 2.25.1
