1* Cadence MACB/GEM Ethernet controller
2
3Required properties:
4- compatible: Should be "cdns,[<chip>-]{macb|gem}"
5 Use "cdns,at91sam9260-macb" for Atmel at91sam9 SoCs or the 10/100Mbit IP
6 available on sama5d3 SoCs.
7 Use "cdns,at32ap7000-macb" for other 10/100 usage or use the generic form: "cdns,macb".
8 Use "cdns,pc302-gem" for Picochip picoXcell pc302 and later devices based on
9 the Cadence GEM, or the generic form: "cdns,gem".
10 Use "cdns,sama5d3-gem" for the Gigabit IP available on Atmel sama5d3 SoCs.
11 Use "cdns,sama5d4-gem" for the Gigabit IP available on Atmel sama5d4 SoCs.
12- reg: Address and length of the register set for the device
13- interrupts: Should contain macb interrupt
14- phy-mode: See ethernet.txt file in the same directory.
15- clock-names: Tuple listing input clock names.
16 Required elements: 'pclk', 'hclk'
17 Optional elements: 'tx_clk'
18- clocks: Phandles to input clocks.
