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. - 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 Example: infiniband@c4000000 { compatible = "hisilicon,hns-roce-v1"; reg = <0x0 0xc4000000 0x0 0x100000>; dma-coherent; eth-handle = <ð2 ð3 ð4 ð5 ð6 ð7>; dsaf-handle = <&soc0_dsa>; node-guid = [00 9A CD 00 00 01 02 03]; #address-cells = <2>; #size-cells = <2>; interrupt-parent = <&mbigen_dsa>; interrupts = <722 1>, <723 1>, <724 1>, <725 1>, <726 1>, <727 1>, <728 1>, <729 1>, <730 1>, <731 1>, <732 1>, <733 1>, <734 1>, <735 1>, <736 1>, <737 1>, <738 1>, <739 1>, <740 1>, <741 1>, <742 1>, <743 1>, <744 1>, <745 1>, <746 1>, <747 1>, <748 1>, <749 1>, <750 1>, <751 1>, <752 1>, <753 1>, <785 1>, <754 4>; interrupt-names = "hns-roce-comp-0", "hns-roce-comp-1", "hns-roce-comp-2", "hns-roce-comp-3", "hns-roce-comp-4", "hns-roce-comp-5", "hns-roce-comp-6", "hns-roce-comp-7", "hns-roce-comp-8", "hns-roce-comp-9", "hns-roce-comp-10", "hns-roce-comp-11", "hns-roce-comp-12", "hns-roce-comp-13", "hns-roce-comp-14", "hns-roce-comp-15", "hns-roce-comp-16", "hns-roce-comp-17", "hns-roce-comp-18", "hns-roce-comp-19", "hns-roce-comp-20", "hns-roce-comp-21", "hns-roce-comp-22", "hns-roce-comp-23", "hns-roce-comp-24", "hns-roce-comp-25", "hns-roce-comp-26", "hns-roce-comp-27", "hns-roce-comp-28", "hns-roce-comp-29", "hns-roce-comp-30", "hns-roce-comp-31", "hns-roce-async", "hns-roce-common"; };
