1 Hisilicon RoCE DT description
2
3 Hisilicon RoCE engine is a part of network subsystem.
4 It works depending on other part of network subsystem, such as gmac and
5 dsa fabric.
6
7 Additional properties are described here:
8
9 Required properties:
10 - compatible: Should contain "hisilicon,hns-roce-v1".
11 - reg: Physical base address of the RoCE driver and
12 length of memory mapped region.
13 - eth-handle: phandle, specifies a reference to a node
14 representing a ethernet device.
15 - dsaf-handle: phandle, specifies a reference to a node
16 representing 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
20 Optional properties:
21 - dma-coherent: Present if DMA operations are coherent.
22 - interrupts: should contain 32 completion event irq,1 async event irq
23 and 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
