      1Hisilicon RoCE DT description
      2
      3Hisilicon RoCE engine is a part of network subsystem.
      4It works depending on other part of network subsystem, such as gmac and
      5dsa fabric.
      6
      7Additional properties are described here:
      8
      9Required properties:
     10- compatible: Should contain "hisilicon,hns-roce-v1".
     11- reg: Physical base address of the RoCE driver and
     12length of memory mapped region.
     13- eth-handle: phandle, specifies a reference to a node
     14representing a ethernet device.
     15- dsaf-handle: phandle, specifies a reference to a node
     16representing a dsaf device.
     17- node_guid: a number that uniquely identifies a device or component
     18- #address-cells: must be 2
     19- #size-cells: must be 2
     20Optional properties:
     21- dma-coherent: Present if DMA operations are coherent.
     22- interrupts: should contain 32 completion event irq,1 async event irq
     23and 1 event overflow irq.
     24- interrupt-names:should be one of 34 irqs for roce device
     25  - hns-roce-comp-0 ~ hns-roce-comp-31: 32 complete event irq
     26  - hns-roce-async: 1 async event irq
     27  - hns-roce-common: named common exception warning irq
