+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.
+- phys: the phandle for the PHY port
+- phy-names: must contain "dphy"
+
+port node
+-------------------
+
+The device node should contain one 'ports' child node, with children 'port'
+with child 'endpoint'.
+nodes, according to the bindings defined in 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

I would remove those extra `---`, and keep as:
...node

The same applies for the title.
