This patch series add a ISP(Camera) v4l2 driver for rockchip rk3288/rk3399 SoC.
Kernel Branch: https://github.com/wzyy2/linux/tree/rkisp1/drivers/media/platform/rockchip/isp1 Below are some infomations about driver/hardware: Rockchip ISP1 have many Hardware Blocks(simplied): MIPI --> ISP --> DCrop(Mainpath) --> RSZ(Mainpath) --> DMA(Mainpath) DMA-Input --> --> DCrop(Selfpath) --> RSZ(Selfpath) --> DMA(Selfpath);) (Acutally the TRM(rk3288, isp) could be found online...... which contains a more detailed block diagrams ;-P) The funcitons of each hardware block: Mainpath : up to 4k resolution, support raw/yuv format Selfpath : up tp 1080p, support rotate, support rgb/yuv format RSZ: scaling DCrop: crop ISP: 3A, Color processing, Crop MIPI: MIPI Camera interface Media pipelines: Mainpath, Selfpath <-- ISP subdev <-- MIPI <-- Sensor 3A stats <-- <-- 3A parms Code struct: capture.c : Mainpath, Selfpath, RSZ, DCROP : capture device. rkisp1.c : ISP : v4l2 sub-device. isp_params.c : 3A parms : output device. isp_stats.c : 3A stats : capture device. mipi_dphy_sy.c : MIPI : sperated v4l2 sub-device. Usage: ChromiumOS: use below v4l2-ctl command to capture frames. v4l2-ctl --verbose -d /dev/video4 --stream-mmap=2 --stream-to=/tmp/stream.out --stream-count=60 --stream-poll use below command to playback the video on your PC. mplayer /tmp/stream.out -loop 0 --demuxer=rawvideo --rawvideo=w=800:h=600:size=$((800*600*2)):format=yuy2 or mplayer ./stream.out -loop 0 -demuxer rawvideo -rawvideo w=800:h=600:size=$((800*600*2)):format=yuy2 Linux: use rkcamsrc gstreamer plugin(just a modified v4l2src) to preview. gst-launch-1.0 rkcamsrc device=/dev/video0 io-mode=4 disable-3A=true videoconvert ! video/x-raw,format=NV12,width=640,height=480 ! kmssink Jacob Chen (7): media: rkisp1: add rockchip isp1 driver media: rkisp1: add Rockchip MIPI Synopsys DPHY driver dt-bindings: Document the Rockchip ISP1 bindings dt-bindings: Document the Rockchip MIPI RX D-PHY bindings ARM: dts: rockchip: add isp node for rk3288 ARM: dts: rockchip: add rx0 mipi-phy for rk3288 MAINTAINERS: add entry for Rockchip ISP1 driver Jeffy Chen (1): media: rkisp1: Add user space ABI definitions Shunqian Zheng (3): media: videodev2.h, v4l2-ioctl: add rkisp1 meta buffer format arm64: dts: rockchip: add isp0 node for rk3399 arm64: dts: rockchip: add rx0 mipi-phy for rk3399 .../devicetree/bindings/media/rockchip-isp1.txt | 61 + .../bindings/media/rockchip-mipi-dphy.txt | 77 + MAINTAINERS | 10 + arch/arm/boot/dts/rk3288.dtsi | 24 + arch/arm64/boot/dts/rockchip/rk3399.dtsi | 26 + drivers/media/platform/Kconfig | 10 + drivers/media/platform/Makefile | 1 + drivers/media/platform/rockchip/isp1/Makefile | 8 + drivers/media/platform/rockchip/isp1/capture.c | 1691 ++++++++++++++++++++ drivers/media/platform/rockchip/isp1/capture.h | 46 + drivers/media/platform/rockchip/isp1/common.h | 330 ++++ drivers/media/platform/rockchip/isp1/dev.c | 632 ++++++++ drivers/media/platform/rockchip/isp1/isp_params.c | 1556 ++++++++++++++++++ drivers/media/platform/rockchip/isp1/isp_params.h | 81 + drivers/media/platform/rockchip/isp1/isp_stats.c | 537 +++++++ drivers/media/platform/rockchip/isp1/isp_stats.h | 81 + .../media/platform/rockchip/isp1/mipi_dphy_sy.c | 805 ++++++++++ drivers/media/platform/rockchip/isp1/regs.c | 251 +++ drivers/media/platform/rockchip/isp1/regs.h | 1578 ++++++++++++++++++ drivers/media/platform/rockchip/isp1/rkisp1.c | 1230 ++++++++++++++ drivers/media/platform/rockchip/isp1/rkisp1.h | 130 ++ drivers/media/v4l2-core/v4l2-ioctl.c | 2 + include/uapi/linux/rkisp1-config.h | 554 +++++++ include/uapi/linux/videodev2.h | 4 + 24 files changed, 9725 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/rockchip-isp1.txt create mode 100644 Documentation/devicetree/bindings/media/rockchip-mipi-dphy.txt create mode 100644 drivers/media/platform/rockchip/isp1/Makefile create mode 100644 drivers/media/platform/rockchip/isp1/capture.c create mode 100644 drivers/media/platform/rockchip/isp1/capture.h create mode 100644 drivers/media/platform/rockchip/isp1/common.h create mode 100644 drivers/media/platform/rockchip/isp1/dev.c create mode 100644 drivers/media/platform/rockchip/isp1/isp_params.c create mode 100644 drivers/media/platform/rockchip/isp1/isp_params.h create mode 100644 drivers/media/platform/rockchip/isp1/isp_stats.c create mode 100644 drivers/media/platform/rockchip/isp1/isp_stats.h create mode 100644 drivers/media/platform/rockchip/isp1/mipi_dphy_sy.c create mode 100644 drivers/media/platform/rockchip/isp1/regs.c create mode 100644 drivers/media/platform/rockchip/isp1/regs.h create mode 100644 drivers/media/platform/rockchip/isp1/rkisp1.c create mode 100644 drivers/media/platform/rockchip/isp1/rkisp1.h create mode 100644 include/uapi/linux/rkisp1-config.h -- 2.15.0
