    The "interrupt-names" prop is very desirable for so many interrupts.

    The node names should be generic and "0x" should be omitted, i.e. 
"infiniband@c4000000".

Hi Sergei Shtylyov, thanks for reviewing
I have modified the binding referred to your advice and the bindings of other module.
I will send a new patch in future.

Thanks
Lijun Ou

+HiSilicon RoCE DT description

+HiSilicon RoCE engine is a part of network subsystem.
+It works depending on other part of network wubsytem, such as, gmac and
+dsa fabric.
+
+Additional properties are described here:
+
+Required properties:
+- compatible: Should contain "hisilicon,hns-roce-v1".
+- reg: Physical base address of the roce driver and
+length of memory mapped region.
+- eth-handle: phandle, specifies a reference to a node
+representing a ethernet device.
+- dsaf-handle: phandle, specifies a reference to a node
+representing a dsaf device.
+- #address-cells: must be 2
+- #size-cells: must be 2
+Optional properties:
+- dma-coherent: Present if DMA operations are coherent.
+- interrupt-parent: the interrupt parent of this device.
+- interrupts: should contain 32 completion event irq,1 async event irq
+and 1 event overflow irq.
+Example:
+	rocee@0xc4000000 {
