+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>;
+ };
+ };
+ };
