    +Synopsys DesignWare CSI-2 Host controller
    +
    +Description
    +-----------
    +
    +This HW block is used to receive image coming from an MIPI CSI-2 compatible
    +camera.
    +
    +Required properties:
    +- compatible : shall be "snps,dw-csi"
    +- reg : physical base address and size of the device memory
    + mapped registers;
    +- interrupts : DW CSI-2 Host interrupts
    +- phys : List of one PHY specifier (as defined in
    + Documentation/devicetree/bindings/phy/phy-bindings.txt).
    + This PHY is a MIPI DPHY working in RX mode.
    +- resets : Reference to a reset controller (optional)
    +
    +The per-board settings:
    + - port sub-node describing a single endpoint connected to the camera as
    + described in video-interfaces.txt[1].
    +
    +Example:
    +
    + csi2: csi2@3000 {
    + compatible = "snps,dw-csi";
    + #address-cells = <1>;
    + #size-cells = <0>;
    + reg = < 0x03000 0x7FF>;
    + phys = <&mipi_dphy_rx>;
    + resets = <&dw_rst 1>;
    + interrupts = <2>;
    +
    + port@0 {
    + reg = <0>;
    + csi_ep1: endpoint {
    + remote-endpoint = <&camera_1>;
    + data-lanes = <1 2>;
    + };
    + };
    + };
