+Rockchip SoC Image Signal Processing unit v1
+----------------------------------------------
+
+Rockchip ISP1 is the Camera interface for the Rockchip series of SoCs
+which contains image processing, scaling, and compression funcitons.
+
+Required properties:
+- compatible: value should be one of the following
+ "rockchip,rk3288-cif-isp";
+ "rockchip,rk3399-cif-isp";
+- reg : offset and length of the register set for the device.
+- interrupts: should contain ISP interrupt.
+- clocks: phandle to the required clocks.
+- clock-names: required clock name.
+- iommus: required a iommu node.
+
+port node
+-------------------
+
+The device node should contain one 'port' child node with child 'endpoint'
+nodes, according to the bindings defined in Documentation/devicetree/bindings/
+media/video-interfaces.txt.
+
+- endpoint(parallel):
+ - remote-endpoint: Connecting to a sensor with a parallel video bus.
+ - parallel_bus properties: Refer to Documentation/devicetree/bindings/
+ media/video-interfaces.txt.
+- endpoint(mipi):
+ - remote-endpoint: Connecting to Rockchip MIPI-DPHY,
+ which is defined in rockchip-mipi-dphy.txt.
+
+The port node must contain at least one endpoint, either parallel or mipi.
+It could have multiple endpoints, but please note the hardware don't support
+two sensors work at a time, they are supposed to work asynchronously.
+
+Device node example
+-------------------
+
+ isp0: isp0@ff910000 {
+ compatible = "rockchip,rk3399-cif-isp";
+ reg = <0x0 0xff910000 0x0 0x4000>;
+ interrupts = <GIC_SPI 43 IRQ_TYPE_LEVEL_HIGH 0>;
+ clocks = <&cru SCLK_ISP0>,
+ <&cru ACLK_ISP0>, <&cru ACLK_ISP0_WRAPPER>,
+ <&cru HCLK_ISP0>, <&cru HCLK_ISP0_WRAPPER>;
+ clock-names = "clk_isp",
+ "aclk_isp", "aclk_isp_wrap",
+ "hclk_isp", "hclk_isp_wrap";
+ power-domains = <&power RK3399_PD_ISP0>;
+ iommus = <&isp0_mmu>;
+
+ port {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ /* mipi */
+ isp0_mipi_in: endpoint@0 {
+ reg = <0>;
+ remote-endpoint = <&dphy_rx0_out>;
+ };
+
+ /* parallel */
+ isp0_parallel_in: endpoint@1 {
+ reg = <1>;
+ remote-endpoint = <&ov5640_out>;
+ bus-width = <8>;
+ };
+ };
+ };
