+Allwinner V3s Camera Sensor Interface
+------------------------------
+
+Required properties:
+ - compatible: value must be "allwinner,sun8i-v3s-csi"
+ - reg: base address and size of the memory-mapped region.
+ - interrupts: interrupt associated to this IP
+ - clocks: phandles to the clocks feeding the CSI
+ * ahb: the CSI interface clock
+ * mod: the CSI module clock
+ * ram: the CSI DRAM clock
+ - clock-names: the clock names mentioned above
+ - resets: phandles to the reset line driving the CSI
+
+- ports: A ports node with endpoint definitions as defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+
+ csi1: csi@01cb4000 {
+ compatible = "allwinner,sun8i-v3s-csi";
+ reg = <0x01cb4000 0x1000>;
+ interrupts = <GIC_SPI 84 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&ccu CLK_BUS_CSI>,
+ <&ccu CLK_CSI1_SCLK>,
+ <&ccu CLK_DRAM_CSI>;
+ clock-names = "ahb", "mod", "ram";
+ resets = <&ccu RST_BUS_CSI>;
+
+ port {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ /* Parallel bus endpoint */
+ csi1_ep: endpoint {
+ remote-endpoint = <&adv7611_ep>;
+ bus-width = <16>;
+ data-shift = <0>;
+
+ /* If hsync-active/vsync-active are missing,
+ embedded BT.656 sync is used */
+ hsync-active = <0>; /* Active low */
+ vsync-active = <0>; /* Active low */
+ data-active = <1>; /* Active high */
+ pclk-sample = <1>; /* Rising */
+ };
+ };
+ };
