Hello, Here's the fourth version of the Xilinx FPGA Video IP Cores kernel drivers.
I won't detail in great lengths the Xilinx Video IP architecture here, as that would result in dozens of pages of documentation. The interested reader can refer to the Zynq ZC702 Base TRD (Targeted Reference Design) User Guide (http://www.xilinx.com/support/documentation/boards_and_kits/zc702_zvik/2014_2/ug925-zynq-zc702-base-trd.pdf). In a nutshell, the Xilinx Video IP Cores architecture specifies how video-related IP cores need to be designed to interoperate and how to assemble them in pipelines of various complexities. The concepts map neatly to the media controller architecture, which this patch set uses extensively. The series starts with various new V4L2 core features, bug fixes or cleanups, with a small documentation enhancement (01/10), the addition of new media bus formats needed by the new drivers (02/10 to 04/10) and a new V4L2 OF link parsing function (05/10). The next two patches (06/10 and 07/10) fix two race conditions in videobuf2. I'd like to get them in v3.19, either as part of this series or independently. The last three patches are the core of this series. Patch 08/10 adds support for the Xilinx Video IP architecture core in the form of a base object to model video IP cores (xilinx-vip.c - Video IP), a framework that parses a DT representation of a video pipeline and connects the corresponding V4L2 subdevices together (xilinx-vipp.c - Video IP Pipeline) and a glue between the Video DMA engine driver and the V4L2 API (xilinx-dma.c). Patch à9/10 adds a driver for the Video Timing Controller (VTC) IP core. While not strictly a video processing IP core, the VTC is required by other video IP core drivers. Finally, patch 10/10 adds a first video IP core driver for the Test Pattern Generator (TPG). Drivers for other IP cores will be added in the future. Changes since v3: - Drop the three Xilinx Video DMA patches since they have been merged in the dmaengine tree - Manage the subdevs clocks explicitly - Add and use resource init and cleanup helpers - Rename V4L2_MBUS_FMT_* to MEDIA_BUS_FMT_* - Cleanup unused vdma configuration. - Return buffers to vb2 when media pipeline start fails Cc: devicet...@vger.kernel.org Hyun Kwon (2): v4l: Sort YUV formats of v4l2_mbus_pixelcode v4l: Add VUY8 24 bits bus format Laurent Pinchart (8): media: entity: Document the media_entity_ops structure v4l: Add RBG and RGB 8:8:8 media bus formats on 24 and 32 bit busses v4l: of: Add v4l2_of_parse_link() function v4l: vb2: Fix race condition in vb2_fop_poll v4l: vb2: Fix race condition in _vb2_fop_release v4l: xilinx: Add Xilinx Video IP core v4l: xilinx: Add Video Timing Controller driver v4l: xilinx: Add Test Pattern Generator driver Documentation/DocBook/media/v4l/subdev-formats.xml | 719 +++++++++------- .../devicetree/bindings/media/xilinx/video.txt | 52 ++ .../devicetree/bindings/media/xilinx/xlnx,v-tc.txt | 33 + .../bindings/media/xilinx/xlnx,v-tpg.txt | 71 ++ .../bindings/media/xilinx/xlnx,video.txt | 55 ++ MAINTAINERS | 10 + drivers/media/platform/Kconfig | 1 + drivers/media/platform/Makefile | 2 + drivers/media/platform/xilinx/Kconfig | 23 + drivers/media/platform/xilinx/Makefile | 5 + drivers/media/platform/xilinx/xilinx-dma.c | 753 +++++++++++++++++ drivers/media/platform/xilinx/xilinx-dma.h | 109 +++ drivers/media/platform/xilinx/xilinx-tpg.c | 925 +++++++++++++++++++++ drivers/media/platform/xilinx/xilinx-vip.c | 296 +++++++ drivers/media/platform/xilinx/xilinx-vip.h | 233 ++++++ drivers/media/platform/xilinx/xilinx-vipp.c | 669 +++++++++++++++ drivers/media/platform/xilinx/xilinx-vipp.h | 49 ++ drivers/media/platform/xilinx/xilinx-vtc.c | 380 +++++++++ drivers/media/platform/xilinx/xilinx-vtc.h | 42 + drivers/media/v4l2-core/v4l2-of.c | 61 ++ drivers/media/v4l2-core/videobuf2-core.c | 35 +- include/media/media-entity.h | 9 + include/media/v4l2-of.h | 27 + include/uapi/linux/Kbuild | 1 + include/uapi/linux/media-bus-format.h | 19 +- include/uapi/linux/xilinx-v4l2-controls.h | 73 ++ 26 files changed, 4310 insertions(+), 342 deletions(-) create mode 100644 Documentation/devicetree/bindings/media/xilinx/video.txt create mode 100644 Documentation/devicetree/bindings/media/xilinx/xlnx,v-tc.txt create mode 100644 Documentation/devicetree/bindings/media/xilinx/xlnx,v-tpg.txt create mode 100644 Documentation/devicetree/bindings/media/xilinx/xlnx,video.txt create mode 100644 drivers/media/platform/xilinx/Kconfig create mode 100644 drivers/media/platform/xilinx/Makefile create mode 100644 drivers/media/platform/xilinx/xilinx-dma.c create mode 100644 drivers/media/platform/xilinx/xilinx-dma.h create mode 100644 drivers/media/platform/xilinx/xilinx-tpg.c create mode 100644 drivers/media/platform/xilinx/xilinx-vip.c create mode 100644 drivers/media/platform/xilinx/xilinx-vip.h create mode 100644 drivers/media/platform/xilinx/xilinx-vipp.c create mode 100644 drivers/media/platform/xilinx/xilinx-vipp.h create mode 100644 drivers/media/platform/xilinx/xilinx-vtc.c create mode 100644 drivers/media/platform/xilinx/xilinx-vtc.h create mode 100644 include/uapi/linux/xilinx-v4l2-controls.h -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
