This series includes below changes to allow capturing from HDMI-to-CSI bridges. - Add DV timing, EDID and log status V4L2 IOCTLs - Subscribe V4L2_EVENT_SOURCE_CHANGE - Implement V4L2 device notify callback to report queue error on source change during active streaming. - Add support for NV16 V4L2 Pixel format. - Add x8 capture by multiple ports gang up for 4K captures from HDMI-to-CSI bridges. Note: These patches are tested with TC358840 HDMI-to-CSI bridge. This series also include below fixes - Allow format change for subdevs that don't have crop support. - Correct V4L2 Pixel format for RGB888_1X24 - Enable VI pixel transform for YUV and RGB formats. Delta between patch versions: [v3]: Includes below changes based on v2 feedback - Correct V4L2 pixel formats for RGB and YUV. - Sets V4L2_IN_CAP_DV_TIMINGS capability for v4l2 input. - Updates V4L2_FWNODE_CSI2_MAX_DATA_LANES to 8 and uses data-lanes property of Tegra CSI device graph endpoint for 8 lanes. - Added V4L2 custom control V4L2_CID_TEGRA_SYNCPT_TIMEOUT_RETRY for HDMI-to-CSI bridge debug purposes. [v2]: v1 + additional patch for x8 capture support Sowjanya Komatineni (13): media: tegra-video: Use zero crop settings if subdev has no get_selection media: tegra-video: Enable VI pixel transform for YUV and RGB formats media: tegra-video: Fix V4L2 pixel format RGB and YUV media: tegra-video: Add support for V4L2_PIX_FMT_NV16 media: tegra-video: Add DV timing support media: tegra-video: Add support for EDID ioctl ops media: tegra-video: Add support for VIDIOC_LOG_STATUS ioctl media: tegra-video: Add support for V4L2_EVENT_SOURCE_CHANGE media: tegra-video: Implement V4L2 device notify callback media: v4l2-fwnode: Update V4L2_FWNODE_CSI2_MAX_DATA_LANES to 8 dt-bindings: tegra: Update csi data-lanes to maximum 8 lanes media: tegra-video: Add support for x8 captures with gang ports media: tegra-video: Add custom V4L2 control V4L2_CID_TEGRA_SYNCPT_TIMEOUT_RETRY .../display/tegra/nvidia,tegra20-host1x.txt | 4 +- drivers/media/platform/ti-vpe/cal-camerarx.c | 2 +- drivers/staging/media/tegra-video/csi.c | 35 ++- drivers/staging/media/tegra-video/csi.h | 14 +- drivers/staging/media/tegra-video/tegra210.c | 340 ++++++++++++++------- drivers/staging/media/tegra-video/vi.c | 338 +++++++++++++++++--- drivers/staging/media/tegra-video/vi.h | 23 +- drivers/staging/media/tegra-video/video.c | 18 ++ include/media/v4l2-fwnode.h | 2 +- 9 files changed, 615 insertions(+), 161 deletions(-)
