Freescale i.MX Media Video Device ================================= Video Media Controller node --------------------------- This is the media controller node for video capture support. It is a virtual device that lists the camera serial interface nodes that the media device will control. Required properties: - compatible : "fsl,imx-capture-subsystem"; - ports : Should contain a list of phandles pointing to camera sensor interface ports of IPU devices example: capture-subsystem { compatible = "fsl,imx-capture-subsystem"; ports = <&ipu1_csi0>, <&ipu1_csi1>; }; mipi_csi2 node -------------- This is the device node for the MIPI CSI-2 Receiver core in the i.MX SoC. This is a Synopsys Designware MIPI CSI-2 host controller core combined with a D-PHY core mixed into the same register block. In addition this device consists of an i.MX-specific "CSI2IPU gasket" glue logic, also controlled from the same register block. The CSI2IPU gasket demultiplexes the four virtual channel streams from the host controller's 32-bit output image bus onto four 16-bit parallel busses to the i.MX IPU CSIs. Required properties: - compatible : "fsl,imx6-mipi-csi2"; - reg : physical base address and length of the register set; - clocks : the MIPI CSI-2 receiver requires three clocks: hsi_tx (the D-PHY clock), video_27m (D-PHY PLL reference clock), and eim_podf; - clock-names : must contain "dphy", "ref", "pix"; - port@* : five port nodes must exist, containing endpoints connecting to the source and sink devices according to of_graph bindings. The first port is an input port, connecting with a MIPI CSI-2 source, and ports 1 through 4 are output ports connecting with parallel bus sink endpoint nodes and correspond to the four MIPI CSI-2 virtual channel outputs. Optional properties: - interrupts : must contain two level-triggered interrupts, in order: 100 and 101;
