+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-plat"
+- reg : physical base address and size of the device memory mapped
+ registers;
+- interrupts : CSI-2 Host interrupt
+- snps,output-type : Core output to be used (IPI-> 0 or IDI->1 or BOTH->2)
+ These values choose which of the Core outputs will be used,
+ it can be Image Data Interface or Image Pixel Interface.
+- 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_1: csi2@3000 {
+ compatible = "snps,dw-csi-plat";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = < 0x03000 0x7FF>;
+ interrupts = <2>;
+ output-type = <2>;
+ resets = <&dw_rst 1>;
+ phys = <&mipi_dphy_rx1 0>;
+ phy-names = "csi2-dphy";
+
+ /* CSI-2 per-board settings */
+ port@1 {
+ reg = <1>;
+ csi1_ep1: endpoint {
+ remote-endpoint = <&camera_1>;
+ data-lanes = <1 2>;
+ };
+ };
+ port@2 {
+ csi1_ep2: endpoint {
+ remote-endpoint = <&vif1_ep>;
+ };
+ };
+ };
