Hi all, Cleanups and fixes, second iteration. The main idea here is to address two issues, and while at it, clean the driver a bit. The first issue can be found in Patch 1, when the Request API is used, the CAPTURE buffer should be returned _before_ the OUTPUT buffer, to avoid waking up userspace prematurely. I noticed this issue while working on the rkvdec driver, but this time I've decided to tackle it at the core, in v4l2_m2m_buf_done_and_job_finish(). The second issue is a simple compliance issue, which is solved by refactoring the driver, dealing with internal set format properly. Changes v2: * Fix compile warning introduced by patch 6. * I'm adding two additional patches this time. Patch 7 converts the binding to json-schema, and patch 8 puts linux-rockchip mailing list in MAINTAINERS. Thanks, Ezequiel Ezequiel Garcia (8): v4l2-mem2mem: return CAPTURE buffer first hantro: Set buffers' zeroth plane payload in .buf_prepare hantro: Use v4l2_m2m_buf_done_and_job_finish hantro: Remove unneeded hantro_dec_buf_finish hantro: Move H264 motion vector calculation to a helper hantro: Refactor for V4L2 API spec compliancy dt-bindings: rockchip-vpu: Convert bindings to json-schema hantro: Add linux-rockchip mailing list to MAINTAINERS .../bindings/media/rockchip-vpu.txt | 43 ------- .../bindings/media/rockchip-vpu.yaml | 82 +++++++++++++ MAINTAINERS | 3 +- drivers/media/v4l2-core/v4l2-mem2mem.c | 11 +- drivers/staging/media/hantro/hantro.h | 7 +- drivers/staging/media/hantro/hantro_drv.c | 37 ++---- drivers/staging/media/hantro/hantro_hw.h | 31 +++++ drivers/staging/media/hantro/hantro_v4l2.c | 111 +++++++++--------- 8 files changed, 194 insertions(+), 131 deletions(-) delete mode 100644 Documentation/devicetree/bindings/media/rockchip-vpu.txt create mode 100644 Documentation/devicetree/bindings/media/rockchip-vpu.yaml
