+  The order may be changed as long as they correspond to the interrupts
+  property. Currently, only i.mx7 uses "int1" and "int2". They correspond to
+  tx/rx queues 1 and 2. "int0" will be used for queue 0 and ENET_MII interrupts.
+  For imx6sx, "int0" handles all 3 queues and ENET_MII. "pps" is for the pulse
+  per second interrupt associated with 1588 precision time protocol(PTP).
