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; |
