+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
+    * bus: 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.
+  Currently, the driver only support the parallel interface. So, a single port
+  node with one endpoint and parallel bus is supported.
+
+Example:
+
+	csi1: csi@1cb4000 {
+		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 = "bus", "mod", "ram";
+		resets = <&ccu RST_BUS_CSI>;
+
+		port {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			/* Parallel bus endpoint */
+			csi1_ep: endpoint {
+				remote-endpoint = <&adv7611_ep>;

Not sure whether syntax for these files is proper reStructuredText/Markdown,
but the underline-ish style expects the title and underline having same length.

The binding files are not rst/md format, but still the comment is just 
good style.

What the driver supports is not relevant. Please document what the h/w 
has.

These are not needed with a single endpoint.
