This initial support implements H264 decoding, VP8 decoding and JPEG encoding. This has been tested on STM32MP257F-EV1 evaluation board. =========== = history = =========== version 6: - Use a single file for VDEC and VENC variants as suggested by Alex Bee - Fix some typos raised by Sebastian Fricke - Add Krzysztof Kozlowski Reviewed-by version 5: - Precise that video decoding as been successfully tested up to full HD - Add Nicolas Dufresne Reviewed-by version 4: - Fix comments from Nicolas about dropping encoder raw steps version 3: - Fix remarks from Krzysztof Kozlowski: - drop "items", we keep simple enum in such case - drop second example - it is the same as the first - Drop unused node labels as suggested by Conor Dooley - Revisit min/max resolutions as suggested by Nicolas Dufresne version 2: - Fix remarks from Krzysztof Kozlowski on v1: - single video-codec binding for both VDEC/VENC - get rid of "-names" - use of generic node name "video-codec" version 1: - Initial submission Hugues Fruchet (5): dt-bindings: media: Document STM32MP25 VDEC & VENC video codecs media: hantro: add support for STM32MP25 VDEC media: hantro: add support for STM32MP25 VENC arm64: dts: st: add video decoder support to stm32mp255 arm64: dts: st: add video encoder support to stm32mp255 .../media/st,stm32mp25-video-codec.yaml | 49 +++++ arch/arm64/boot/dts/st/stm32mp251.dtsi | 12 ++ arch/arm64/boot/dts/st/stm32mp255.dtsi | 17 ++ drivers/media/platform/verisilicon/Kconfig | 14 +- drivers/media/platform/verisilicon/Makefile | 3 + .../media/platform/verisilicon/hantro_drv.c | 4 + .../media/platform/verisilicon/hantro_hw.h | 2 + .../platform/verisilicon/stm32mp25_vpu_hw.c | 186 ++++++++++++++++++ 8 files changed, 284 insertions(+), 3 deletions(-) create mode 100644 Documentation/devicetree/bindings/media/st,stm32mp25-video-codec.yaml create mode 100644 drivers/media/platform/verisilicon/stm32mp25_vpu_hw.c
