Please use the media_tree master, that's what I use as well. I did some more testing and there is something weird going on. I have a Leopard Imaging camera expansion board (LI-JTX1-MIPI-ADPT) with three camera connectors. See here for the datasheet: https://www.leopardimaging.com/uploads/LI-TX1-KIT-IMX274M12-T_datasheet.pdf The first connector (with an IMX274) causes this error: $ v4l2-ctl -d1 --stream-mmap [ 599.265885] video4linux video1: MW_ACK_DONE syncpt timeout: -11 [ 599.473883] video4linux video1: MW_ACK_DONE syncpt timeout: -11 [ 599.681904] video4linux video1: frame start syncpt timeout: -11 [ 599.681909] video4linux video1: MW_ACK_DONE syncpt timeout: -11 >> >>> This series include, >>> >>> VI I2C related fixes >>> - Camera sensor programming happens through VI I2C which is on host1x bus. >>> - These patches includes device tree and I2C driver fixes for VI I2C. >>> >>> Tegra video driver updates >>> - TPG Vs Non-TPG based on Kconfig >>> - Support for external sensor video capture based on device graph from DT. >>> - Support for selection ioctl operations >>> - Tegra MIPI CSI pads calibration >>> - CSI T-CLK and T-HS settle time computation based on clock rates. >>> >>> Host1x driver updates >>> - Adds API to allow creating mipi device for specific device node. >>> - Splits MIPI pads calibrate start and waiting for calibration to be done. >>> >>> Device tree updates >>> - Adds camera connector 2V8, 1V8, 1V2 regulator supplies to Jetson TX1 DT. >>> - Enabled VI and CSI support in Jetson Nano DT. >>> >>> >>> Delta between patch versions: >>> >>> [v2]: Includes below changes based on v1 feedback >>> - dt-binding document and the driver update for device graph to use >>> separate ports for sink endpoint and source endpoint for csi. >>> - Use data-lanes endpoint property for csi. >>> - Update tegra_mipi_request() to take device node pointer argument >>> rather than adding extra API. >>> - Remove checking for clk pointer before clk_disable. >>> >>> >>> Sowjanya Komatineni (18): >>> dt-bindings: i2c: tegra: Document Tegra210 VI I2C clocks and >>> power-domains >>> arm64: tegra: Add missing clocks and power-domains to Tegra210 VI I2C >>> i2c: tegra: Don't mark VI I2C as IRQ safe runtime PM >>> i2c: tegra: Fix the error path in tegra_i2c_runtime_resume >>> i2c: tegra: Fix runtime resume to re-init VI I2C >>> i2c: tegra: Avoid tegra_i2c_init_dma() for Tegra210 vi i2c >>> media: tegra-video: Fix channel format alignment >>> media: tegra-video: Enable TPG based on kernel config >>> media: tegra-video: Update format lookup to offset based >>> dt-bindings: tegra: Update VI and CSI bindings with port info >>> media: tegra-video: Add support for external sensor capture >>> media: tegra-video: Add support for selection ioctl ops >>> gpu: host1x: mipi: Update tegra_mipi_request() to be node based >>> gpu: host1x: mipi: Split tegra_mipi_calibrate and tegra_mipi_wait >>> media: tegra-video: Add CSI MIPI pads calibration >>> media: tegra-video: Compute settle times based on the clock rate >>> arm64: tegra: jetson-tx1: Add camera supplies >>> arm64: tegra: Enable Tegra VI CSI support for Jetson Nano >>> >>> .../display/tegra/nvidia,tegra20-host1x.txt | 92 ++- >>> .../devicetree/bindings/i2c/nvidia,tegra20-i2c.txt | 19 +- >>> arch/arm64/boot/dts/nvidia/tegra210-p2597.dtsi | 41 ++ >>> arch/arm64/boot/dts/nvidia/tegra210-p3450-0000.dts | 10 + >>> arch/arm64/boot/dts/nvidia/tegra210.dtsi | 6 + >>> drivers/gpu/drm/tegra/dsi.c | 9 +- >>> drivers/gpu/host1x/mipi.c | 30 +- >>> drivers/i2c/busses/i2c-tegra.c | 39 +- >>> drivers/staging/media/tegra-video/Kconfig | 7 + >>> drivers/staging/media/tegra-video/csi.c | 245 ++++++- >>> drivers/staging/media/tegra-video/csi.h | 8 + >>> drivers/staging/media/tegra-video/tegra210.c | 25 +- >>> drivers/staging/media/tegra-video/vi.c | 770 +++++++++++++++++++-- >>> drivers/staging/media/tegra-video/vi.h | 23 +- >>> drivers/staging/media/tegra-video/video.c | 23 +- >>> include/linux/host1x.h | 4 +- >>> 16 files changed, 1251 insertions(+), 100 deletions(-) >>>
