Hello, I'm re-sending a new version of ISP(Camera) v4l2 driver for rockchip rk3399 SoC. I didn't change much from the last version, just applying the suggestions made in the previous one. This patchset is also available at: https://gitlab.collabora.com/koike/linux/tree/rockchip/isp/v8 Libcamera patched to work with this version: https://gitlab.collabora.com/koike/libcamera (also sent to the mailing list) I tested on the rockpi 4 with a rpi v1.3 sensor and also with the Scarlet Chromebook. Known issues (same as in v7): ------------- - Reloading the module doesn't work (there is some missing cleanup when unloading) - When capturing in bayer format, changing the size doesn't seem to affect the image. - crop needs more tests - v4l2-compliance error: fail: v4l2-test-controls.cpp(824): subscribe event for control 'Image Processing Controls' failed test VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT: FAIL It seems that if controls are supported, v4l2-compliance says that controls of type 'Image Processing Controls' are mandatory, is this correct? - It seems there are still some issues with interrupts, but I couldn't isolate them yet. Previous changelog: ------------------- changes in V6: - add mipi txrx phy support - remove bool and enum from uapi header - add buf_prepare op - correct some spelling problems - return all queued buffers when starting stream failed changes in V5: Sync with local changes, - fix the SP height limit - speed up the second stream capture - the second stream can't force sync for rsz when start/stop streaming - add frame id to param vb2 buf - enable luminance maximum threshold changes in V4: - fix some bugs during development - move quantization settings to rkisp1 subdev - correct some spelling problems - describe ports in dt-binding documents changes in V3: - add some comments - fix wrong use of v4l2_async_subdev_notifier_register - optimize two paths capture at a time - remove compose - re-struct headers - add a tmp wiki page: http://opensource.rock-chips.com/wiki_Rockchip-isp1 changes in V2: mipi-phy: - use async probing - make it be a child device of the GRF isp: - add dummy buffer - change the way to get bus configuration, which make it possible to add parallel sensor support in the future(without mipi-phy driver). ------------------ Changes in v8: - Add SPDX in the header - Remove emacs configs - Fix doc style - Remove boiler plate license text Changes in v7: - s/IPU3/RK_ISP1 - s/correspond/corresponding - s/use/uses - s/docuemnt/document - Fix checkpatch errors (lines over 80 and SPDX) - Add TODO to improve docs - Migrate dphy specific code from drivers/media/platform/rockchip/isp1/mipi_dphy_sy.c to drivers/phy/rockchip/phy-rockchip-dphy.c - Drop support for rk3288 - Drop support for dphy txrx - code styling and checkpatch fixes - fixed warning because of unknown entity type - fixed v4l2-compliance errors regarding rkisp1 formats, try formats and default values - fix typo riksp1/rkisp1 - redesign: remove mipi/csi subdevice, sensors connect directly to the isp subdevice in the media topology now. As a consequence, remove the hack in mipidphy_g_mbus_config() where information from the sensor was being propagated through the topology. - From the old dphy: * cache get_remote_sensor() in s_stream * use V4L2_CID_PIXEL_RATE instead of V4L2_CID_LINK_FREQ - Replace stream state with a boolean - code styling and checkpatch fixes - fix stop_stream (return after calling stop, do not reenable the stream) - fix rkisp1_isp_sd_get_selection when V4L2_SUBDEV_FORMAT_TRY is set - fix get format in output (isp_sd->out_fmt.mbus_code was being ignored) - s/intput/input - remove #define sd_to_isp_sd(_sd), add a static inline as it will be reused by the capture - s/strlcpy/strscpy - sort out the locks in isp stats - code styling and checkpatch fixes - s/strlcpy/strscpy - s/strcpy/strscpy - fix config lsc error LSC data table size is 17x17, but when configuring data to ISP, should be aligned to 18x17. That means every last data of last line should be filled with 0, and not filled with the data of next line. - Update new ISP parameters immediately For those sub modules that have shadow registers in core isp, the new programing parameters would not be active if both CIF_ISP_CTRL_ISP_CFG_UPD_PERMANENT and CFG_UPD are not set. Now we configure CFG_UPD to force update the shadow registers when new ISP parameters are configured. - fix some ISP parameters config error Some ISP parameter config functions may override the old enable bit value, because the enable bits of these modules are in the same registers with parameters. So we should save the old enable bits firstly. - code styling and checkpatch fixes - s/strlcpy/strscpy - Fix v4l2-compliance issues: * remove input ioctls media api can be used to define the topology, this input api is not required. Besides it, if an input is enumerated, v4l2-compliance is not happy with G_FMT returning the default colorspace instead of something more specific. * return the pixelformat to the userspace G_/S_/TRY_ FORMAT should return a valid pixelformat to the user, even if the user gave an invalid one * add missing default colorspace and ycbcr * fix wrong pixformat in mp_fmts[] table * add buf type check in s_/g_selection * queue_setup - check sizes * normalize bus_info name * fix field any v4l2-compliance -s complain - set field none when streaming - Fix compiling error: s/vidioc_enum_fmt_vid_cap_mplane/vidioc_enum_fmt_vid_cap - Replace stream state with a boolean The rkisp1_state enum consists only of 3 entries, where 1 is completely unused and the other two respectively mean not streaming or streaming. Replace it with a boolean called "streaming". - Simplify MI interrupt handling Rather than adding unnecessary indirection, just use stream index to handle MI interrupt enable/disable/clear, since the stream index matches the order of bits now, thanks to previous patch. While at it, remove some dead code. - code styling and checkpatch fixes - add link_validate: don't allow a link with bayer/non-bayer mismatch - VIDEO_ROCKCHIP_ISP1 selects VIDEOBUF2_VMALLOC - add PHY_ROCKCHIP_DPHY as a dependency for VIDEO_ROCKCHIP_ISP1 - Fix compilation and runtime errors due to bitrotting The code has bit-rotten since March 2018, fix compilation errors. The new V4L2 async notifier API requires notifiers to be initialized by a call to v4l2_async_notifier_init() before being used, do so. - Add missing module device table - use clk_bulk framework - add missing notifiers cleanups - s/strlcpy/strscpy - normalize bus_info name - fix s_stream error path, stream_cnt wans't being decremented properly - use devm_platform_ioremap_resource() helper - s/deice/device - redesign: remove mipi/csi subdevice, sensors connect directly to the isp subdevice in the media topology now. - remove "saved_state" member from rkisp1_stream struct - Reverse the order of MIs - Simplify MI interrupt handling Rather than adding unnecessary indirection, just use stream index to handle MI interrupt enable/disable/clear, since the stream index matches the order of bits now, thanks to previous patch. While at it, remove some dead code. - code styling and checkpatch fixes - update document with new design and tested example - updated doc with new design and tested example - add phy properties - add ports - add phy-cells Helen Koike (1): MAINTAINERS: add entry for Rockchip ISP1 driver Jacob Chen (9): media: doc: add document for rkisp1 meta buffer format media: rkisp1: add Rockchip MIPI Synopsys DPHY driver media: rkisp1: add Rockchip ISP1 subdev driver media: rkisp1: add ISP1 statistics driver media: rkisp1: add ISP1 params driver media: rkisp1: add capture device driver media: rkisp1: add rockchip isp1 core driver dt-bindings: Document the Rockchip ISP1 bindings dt-bindings: Document the Rockchip MIPI RX D-PHY bindings 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 .../bindings/media/rockchip-isp1.txt | 71 + .../bindings/media/rockchip-mipi-dphy.txt | 38 + Documentation/media/uapi/v4l/meta-formats.rst | 2 + .../uapi/v4l/pixfmt-meta-rkisp1-params.rst | 23 + .../uapi/v4l/pixfmt-meta-rkisp1-stat.rst | 22 + MAINTAINERS | 8 + arch/arm64/boot/dts/rockchip/rk3399.dtsi | 36 + drivers/media/platform/Kconfig | 12 + drivers/media/platform/Makefile | 1 + drivers/media/platform/rockchip/isp1/Makefile | 7 + .../media/platform/rockchip/isp1/capture.c | 1754 +++++++++++++++++ .../media/platform/rockchip/isp1/capture.h | 164 ++ drivers/media/platform/rockchip/isp1/common.h | 101 + drivers/media/platform/rockchip/isp1/dev.c | 675 +++++++ drivers/media/platform/rockchip/isp1/dev.h | 97 + .../media/platform/rockchip/isp1/isp_params.c | 1604 +++++++++++++++ .../media/platform/rockchip/isp1/isp_params.h | 50 + .../media/platform/rockchip/isp1/isp_stats.c | 508 +++++ .../media/platform/rockchip/isp1/isp_stats.h | 60 + drivers/media/platform/rockchip/isp1/regs.c | 223 +++ drivers/media/platform/rockchip/isp1/regs.h | 1525 ++++++++++++++ drivers/media/platform/rockchip/isp1/rkisp1.c | 1286 ++++++++++++ drivers/media/platform/rockchip/isp1/rkisp1.h | 111 ++ drivers/media/v4l2-core/v4l2-ioctl.c | 2 + drivers/phy/rockchip/Kconfig | 8 + drivers/phy/rockchip/Makefile | 1 + drivers/phy/rockchip/phy-rockchip-dphy.c | 408 ++++ include/uapi/linux/rkisp1-config.h | 816 ++++++++ include/uapi/linux/videodev2.h | 4 + 29 files changed, 9617 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 Documentation/media/uapi/v4l/pixfmt-meta-rkisp1-params.rst create mode 100644 Documentation/media/uapi/v4l/pixfmt-meta-rkisp1-stat.rst 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/dev.h 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/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 drivers/phy/rockchip/phy-rockchip-dphy.c create mode 100644 include/uapi/linux/rkisp1-config.h -- 2.22.0
