Hello, Here's the third version of the VSP1 engine (a Video Signal Processor found in several Renesas R-Car SoCs) driver. I'd like to thank all the v1 and v2 reviewers. The VSP1 is a video processing engine that includes a blender, scalers, filters and statistics computation. Configurable data path routing logic allows ordering the internal blocks in a flexible way, making this driver a prime candidate for the media controller API. Due to the configurable nature of the pipeline the driver doesn't use the V4L2 mem-to-mem framework, even though the device usually operates in memory to memory mode. Only the read pixel formatters, up/down scalers, write pixel formatters and LCDC interface are supported at this stage. The patch series starts with a fix for the media controller graph traversal code, a documentation fix and new pixel format and media bus code definitions. The last patch finally adds the VSP1 driver. Changes since v1: - Updated to the v3.11 media controller API changes - Only add the LIF entity to the entities list when the LIF is present - Added a MODULE_ALIAS() - Fixed file descriptions in comment blocks - Removed function prototypes for the unimplemented destroy functions - Fixed a typo in the HST register name - Fixed format propagation for the UDS entities - Added v4l2_capability::device_caps support - Prefix the device name with "platform:" in bus_info - Zero the v4l2_pix_format priv field in the internal try format handler - Use vb2_is_busy() instead of vb2_is_streaming() when setting the format - Use the vb2_ioctl_* handlers where possible Changes since v2: - Use a bitmap to track visited entities during graph traversal - Fixed a typo in the V4L2_MBUS_FMT_ARGB888_1X32 documentation - Fix register macros that were missing a n argument - Mask unused bits when clearing the interrupt status register - Explain why stride alignment to 128 bytes is needed - Use the aligned stride value when computing the image size - Assorted cosmetic changes Laurent Pinchart (5): media: Add support for circular graph traversal v4l: Fix V4L2_MBUS_FMT_YUV10_1X30 media bus pixel code value v4l: Add media format codes for ARGB8888 and AYUV8888 on 32-bit busses v4l: Add V4L2_PIX_FMT_NV16M and V4L2_PIX_FMT_NV61M formats v4l: Renesas R-Car VSP1 driver Documentation/DocBook/media/v4l/pixfmt-nv16m.xml | 170 +++ Documentation/DocBook/media/v4l/pixfmt.xml | 1 + Documentation/DocBook/media/v4l/subdev-formats.xml | 611 +++++------ Documentation/DocBook/media_api.tmpl | 6 + drivers/media/media-entity.c | 14 +- drivers/media/platform/Kconfig | 10 + drivers/media/platform/Makefile | 2 + drivers/media/platform/vsp1/Makefile | 5 + drivers/media/platform/vsp1/vsp1.h | 73 ++ drivers/media/platform/vsp1/vsp1_drv.c | 488 +++++++++ drivers/media/platform/vsp1/vsp1_entity.c | 181 ++++ drivers/media/platform/vsp1/vsp1_entity.h | 68 ++ drivers/media/platform/vsp1/vsp1_lif.c | 238 ++++ drivers/media/platform/vsp1/vsp1_lif.h | 37 + drivers/media/platform/vsp1/vsp1_regs.h | 581 ++++++++++ drivers/media/platform/vsp1/vsp1_rpf.c | 209 ++++ drivers/media/platform/vsp1/vsp1_rwpf.c | 124 +++ drivers/media/platform/vsp1/vsp1_rwpf.h | 53 + drivers/media/platform/vsp1/vsp1_uds.c | 346 ++++++ drivers/media/platform/vsp1/vsp1_uds.h | 40 + drivers/media/platform/vsp1/vsp1_video.c | 1135 ++++++++++++++++++++ drivers/media/platform/vsp1/vsp1_video.h | 144 +++ drivers/media/platform/vsp1/vsp1_wpf.c | 233 ++++ include/linux/platform_data/vsp1.h | 25 + include/media/media-entity.h | 3 + include/uapi/linux/v4l2-mediabus.h | 6 +- include/uapi/linux/videodev2.h | 2 + 27 files changed, 4434 insertions(+), 371 deletions(-) create mode 100644 Documentation/DocBook/media/v4l/pixfmt-nv16m.xml create mode 100644 drivers/media/platform/vsp1/Makefile create mode 100644 drivers/media/platform/vsp1/vsp1.h create mode 100644 drivers/media/platform/vsp1/vsp1_drv.c create mode 100644 drivers/media/platform/vsp1/vsp1_entity.c create mode 100644 drivers/media/platform/vsp1/vsp1_entity.h create mode 100644 drivers/media/platform/vsp1/vsp1_lif.c create mode 100644 drivers/media/platform/vsp1/vsp1_lif.h create mode 100644 drivers/media/platform/vsp1/vsp1_regs.h create mode 100644 drivers/media/platform/vsp1/vsp1_rpf.c create mode 100644 drivers/media/platform/vsp1/vsp1_rwpf.c create mode 100644 drivers/media/platform/vsp1/vsp1_rwpf.h create mode 100644 drivers/media/platform/vsp1/vsp1_uds.c create mode 100644 drivers/media/platform/vsp1/vsp1_uds.h create mode 100644 drivers/media/platform/vsp1/vsp1_video.c create mode 100644 drivers/media/platform/vsp1/vsp1_video.h create mode 100644 drivers/media/platform/vsp1/vsp1_wpf.c create mode 100644 include/linux/platform_data/vsp1.h -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
