+Hisilicon DSA Fabric device controller
+
+Required properties:
+- compatible: should be "hisilicon,hns-dsaf-v1" or "hisilicon,hns-dsaf-v2".
+ "hisilicon,hns-dsaf-v1" is for hip05.
+ "hisilicon,hns-dsaf-v2" is for Hi1610 and Hi1612.
+- dsa-name: dsa fabric name who provide this interface.
+ should be "dsafX", X is the dsaf id.
+- mode: dsa fabric mode string. only support one of dsaf modes like these:
+ "2port-64vf",
+ "6port-16rss",
+ "6port-16vf".
+- interrupt-parent: the interrupt parent of this device.
+- interrupts: should contain the DSA Fabric and rcb interrupt.
+- reg: specifies base physical address(es) and size of the device registers.
+ The first region is external interface control register base and size.
+ The second region is SerDes base register and size.
+ The third region is the PPE register base and size.
+ The fourth region is dsa fabric base register and size.
+ The fifth region is cpld base register and size, it is not required if do not use cpld.
+- phy-handle: phy handle of physicl port, 0 if not any phy device. see ethernet.txt [1].
+- buf-size: rx buffer size, should be 16-1024.
+- desc-num: number of description in TX and RX queue, should be 512, 1024, 2048 or 4096.
