* STMicroelectronics 10/100/1000 Ethernet driver (GMAC)
Required properties:
- compatible: Should be "st,spear600-gmac"
- compatible: Should be "snps,dwmac-<ip_version>" "snps,dwmac"
For backwards compatibility: "st,spear600-gmac" is also supported.
- reg: Address and length of the register set for the device
- interrupt-parent: Should be the phandle for the interrupt controller
that services interrupts for this device
