Jetson TX1 has camera expansion connector and supports custom camera module designed as per TX1 design specification. This series also enables camera capture support for Jetson Nano which has Raspberry PI camera header. This series is tested with IMX219 camera sensor. 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.
