9 Required properties:
10 - compatible: Should contain "hisilicon,hns-ro
11 - reg: Physical base address of the RoCE drive
12 length of memory mapped region.
13 - eth-handle: phandle, specifies a reference t
14 representing a ethernet device.
15 - dsaf-handle: phandle, specifies a reference
16 representing a dsaf device.
17 - node_guid: a number that uniquely identifies
18 - #address-cells: must be 2
19 - #size-cells: must be 2
20 Optional properties:
21 - dma-coherent: Present if DMA operations are
22 - interrupts: should contain 32 completion eve
23 and 1 event overflow irq.
24 - interrupt-names:should be one of 34 irqs for
