+Synopsys DesignWare CSI-2 Host Video Platform
+
+The Synopsys DesignWare CSI-2 Host Video Device subsystem comprises of multiple
+sub-devices represented by separate device tree nodes. Currently this includes:
+plat-csi2, video-device, and dw-mipi-csi.
+
+The sub-subdevices are defined as child nodes of the common 'camera'.
+
+Common 'camera' node
+--------------------
+
+Required properties:
+
+- compatible: must be "snps,plat-csi2", "simple-bus"
+
+The 'camera' node must include at least one 'video-device' and one 'dw-mipi-csi'
+child node.
+
+'video-device' device nodes
+-------------------
+
+Required properties:
+
+- compatible: "snps,video-device"
+- dmas, dma-names: List of one DMA specifier and identifier string (as defined
+ in Documentation/devicetree/bindings/dma/dma.txt) per port. Each port
+ requires a DMA channel with the identifier string set to "vdma" followed by
+ the port index.
+
+Image sensor nodes
+------------------
+
+The sensor device nodes should be added to their control bus controller (e.g.
+I2C0) nodes and linked to a port node in the dw-mipi-csi,using the common video
+interfaces bindings, defined in video-interfaces.txt.
+
+Example:
+
+
+ camera {
+ compatible = "snps,plat-csi2", "simple-bus";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+ video_device: video-device@0x10000 {
+ compatible = "snps,video-device";
+ dmas = <&axi_vdma_0 0>;
+ dma-names = "vdma0";
+ };
+
+ csi2: csi2@0x03000 {
+ compatible = "snps,dw-mipi-csi";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = < 0x03000 0x7FF>;
+ interrupts = <2>;
+ phys = <&mipi_phy_ctrl1 0>;
+ resets = <&csi2_rst 1>;
+
+ output-type = <2>;
+ ipi-mode = <0>;
+ ipi-color-mode = <0>;
+ ipi-auto-flush = <1>;
+ virtual-channel = <0>;
+
+ port@1 {
+ reg = <1>;
+ csi1_ep1: endpoint {
+ remote-endpoint = <&camera>;
+ data-lanes = <1 2>;
+ };
+ };
+ };
+ };
+ };
+
+The dw-mipi-csi device binding is defined in snps,dw-mipi-csi.txt.
