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;
