Some of Allwinner SoCs like A83T and A64 SoCs contain DE2 rotate core which can flip image horizontal and vertical and rotate it in 90 deg. steps. It support a lot of output formats, but a bit less capture formats. All YUV input formats get converted to yuv420p, while RGB formats are preserved. Patches 1-2 fix few issues with DE2 clocks. Patches 3-4 fix register range of DE2 clocks (it would overlap with rotate driver) Patches 5-8 provide binding, implement driver and add nodes. v4l2-compliance SHA: ec55a961487b449bedbe07650674b4965814cf07, 32 bits, 32-bit time_t Compliance test for sun8i-rotate device /dev/video0: Driver Info: Driver name : sun8i-rotate Card type : sun8i-rotate Bus info : platform:sun8i-rotate Driver version : 5.5.0 Capabilities : 0x84208000 Video Memory-to-Memory Streaming Extended Pix Format Device Capabilities Device Caps : 0x04208000 Video Memory-to-Memory Streaming Extended Pix Format Required ioctls: test VIDIOC_QUERYCAP: OK Allow for multiple opens: test second /dev/video0 open: OK test VIDIOC_QUERYCAP: OK test VIDIOC_G/S_PRIORITY: OK test for unlimited opens: OK test invalid ioctls: OK Debug ioctls: test VIDIOC_DBG_G/S_REGISTER: OK (Not Supported) test VIDIOC_LOG_STATUS: OK Input ioctls: test VIDIOC_G/S_TUNER/ENUM_FREQ_BANDS: OK (Not Supported) test VIDIOC_G/S_FREQUENCY: OK (Not Supported) test VIDIOC_S_HW_FREQ_SEEK: OK (Not Supported) test VIDIOC_ENUMAUDIO: OK (Not Supported) test VIDIOC_G/S/ENUMINPUT: OK (Not Supported) test VIDIOC_G/S_AUDIO: OK (Not Supported) Inputs: 0 Audio Inputs: 0 Tuners: 0 Output ioctls: test VIDIOC_G/S_MODULATOR: OK (Not Supported) test VIDIOC_G/S_FREQUENCY: OK (Not Supported) test VIDIOC_ENUMAUDOUT: OK (Not Supported) test VIDIOC_G/S/ENUMOUTPUT: OK (Not Supported) test VIDIOC_G/S_AUDOUT: OK (Not Supported) Outputs: 0 Audio Outputs: 0 Modulators: 0 Input/Output configuration ioctls: test VIDIOC_ENUM/G/S/QUERY_STD: OK (Not Supported) test VIDIOC_ENUM/G/S/QUERY_DV_TIMINGS: OK (Not Supported) test VIDIOC_DV_TIMINGS_CAP: OK (Not Supported) test VIDIOC_G/S_EDID: OK (Not Supported) Control ioctls: test VIDIOC_QUERY_EXT_CTRL/QUERYMENU: OK test VIDIOC_QUERYCTRL: OK test VIDIOC_G/S_CTRL: OK test VIDIOC_G/S/TRY_EXT_CTRLS: OK test VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT: OK test VIDIOC_G/S_JPEGCOMP: OK (Not Supported) Standard Controls: 4 Private Controls: 0 Format ioctls: test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS: OK test VIDIOC_G/S_PARM: OK (Not Supported) test VIDIOC_G_FBUF: OK (Not Supported) test VIDIOC_G_FMT: OK test VIDIOC_TRY_FMT: OK test VIDIOC_S_FMT: OK test VIDIOC_G_SLICED_VBI_CAP: OK (Not Supported) test Cropping: OK (Not Supported) test Composing: OK (Not Supported) test Scaling: OK (Not Supported) Codec ioctls: test VIDIOC_(TRY_)ENCODER_CMD: OK (Not Supported) test VIDIOC_G_ENC_INDEX: OK (Not Supported) test VIDIOC_(TRY_)DECODER_CMD: OK (Not Supported) Buffer ioctls: test VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF: OK test VIDIOC_EXPBUF: OK test Requests: OK (Not Supported) Total for sun8i-rotate device /dev/video0: 45, Succeeded: 45, Failed: 0, Warnings: 0 Best regards, Jernej Jernej Skrabec (8): clk: sunxi-ng: sun8i-de2: Swap A64 and H6 definitions clk: sunxi-ng: sun8i-de2: Fix A83T clocks and reset ARM: dts: sunxi: Fix DE2 clocks register range arm64: dts: allwinner: a64: Fix display clock register range media: dt-bindings: media: Add Allwinner A83T Rotate driver media: sun8i: Add Allwinner A83T Rotate driver ARM: dts: sun8i: a83t: Add device node for rotation core arm64: dts: allwinner: a64: add node for rotation core .../allwinner,sun8i-a83t-de2-rotate.yaml | 70 ++ MAINTAINERS | 8 + arch/arm/boot/dts/sun8i-a83t.dtsi | 13 +- arch/arm/boot/dts/sun8i-r40.dtsi | 2 +- arch/arm/boot/dts/sun8i-v3s.dtsi | 2 +- arch/arm/boot/dts/sunxi-h3-h5.dtsi | 2 +- arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi | 14 +- drivers/clk/sunxi-ng/ccu-sun8i-de2.c | 49 +- drivers/media/platform/Kconfig | 12 + drivers/media/platform/sunxi/Makefile | 1 + .../platform/sunxi/sun8i-rotate/Makefile | 2 + .../sunxi/sun8i-rotate/sun8i-formats.c | 273 ++++++ .../sunxi/sun8i-rotate/sun8i-formats.h | 25 + .../sunxi/sun8i-rotate/sun8i-rotate.c | 924 ++++++++++++++++++ .../sunxi/sun8i-rotate/sun8i-rotate.h | 135 +++ 15 files changed, 1512 insertions(+), 20 deletions(-) create mode 100644 Documentation/devicetree/bindings/media/allwinner,sun8i-a83t-de2-rotate.yaml create mode 100644 drivers/media/platform/sunxi/sun8i-rotate/Makefile create mode 100644 drivers/media/platform/sunxi/sun8i-rotate/sun8i-formats.c create mode 100644 drivers/media/platform/sunxi/sun8i-rotate/sun8i-formats.h create mode 100644 drivers/media/platform/sunxi/sun8i-rotate/sun8i-rotate.c create mode 100644 drivers/media/platform/sunxi/sun8i-rotate/sun8i-rotate.h -- 2.25.0
