+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.
+- interrupt-names:should be one of 34 irqs for roce device
+ - hns-roce-comp-0 ~ hns-roce-comp-31: 32 complete event irq
+ - hns-roce-async: 1 async event irq
+ - hns-roce-common: named common exception warning irq
+Example:
+ infiniband@c4000000 {
+ compatible = "hisilicon,hns-roce-v1";
+ reg = <0x0 0xc4000000 0x0 0x100000>;

+ eth-handle = <&eth2 &eth3 &eth4 &eth5 &eth6 &eth7>;
+ dsaf-handle = <&soc0_dsa>;
+ #address-cells = <2>;
+ #size-cells = <2>;
+ interrupt-parent = <&mbigen_dsa>;
