Hisilicon RoCE DT description
|
||
|
|
|
||
|
|
Hisilicon RoCE engine is a part of network subsystem.
|
||
|
|
It works depending on other part of network subsystem, 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.
|
||
|
|
- node_guid: a number that uniquely identifies a device or component
|
||
|
|
- #address-cells: must be 2
|
||
|
|
- #size-cells: must be 2
|
||
|
|
Optional properties:
|
||
|
|
- dma-coherent: Present if DMA operations are coherent.
|
||
|
|
- 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
|
||
|
|
