+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)
+
+Optional properties(if in IPI mode):
+- snps,ipi-mode : Mode to be used when in IPI(Camera -> 0 or Controller -> 1)
+ This property defines if the controller will use the video
+ timings available
+ in the video stream or if it will use pre-defined ones.
+- snps,ipi-color-mode : Bus depth to be used in IPI (48 bits -> 0 or 16 bits -> 1)
+ This property defines the width of the IPI bus.
+- snps,ipi-auto-flush : Data auto-flush (1 -> Yes or 0 -> No). This property defines
+ if the data is automatically flushed in each vsync or if
+ this process is done manually
+- snps,virtual-channel : Virtual channel where data is present when in IPI mode. This
+ property chooses the virtual channel which IPI will use to
+ retrieve the video stream.
+
+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";
+
+ /* IPI optional Configurations */
+ snps,ipi-mode = <0>;
+ snps,ipi-color-mode = <0>;
+ snps,ipi-auto-flush = <1>;
+ snps,virtual-channel = <0>;
+
+ /* 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>;
+ };
+ };
+ };
