1 * Synopsys ARC EMAC 10/100 Ethernet driver (EMAC)
4 - compatible: Should be "snps,arc-emac"
5 - reg: Address and length of the register set for the device
6 - interrupts: Should contain the EMAC interrupts
7 - max-speed: see ethernet.txt file in the same directory.
8 - phy: see ethernet.txt file in the same directory.
11 - phy-reset-gpios : Should specify the gpio for phy reset
12 - phy-reset-duration : Reset duration in milliseconds. Should present
13 only if property "phy-reset-gpios" is available. Missing the property
14 will have the duration be 1 millisecond. Numbers greater than 1000 are
15 invalid and 1 millisecond will be used instead.
18 The clock frequency is needed to calculate and set polling period of EMAC.
19 It must be provided by one of:
20 - clock-frequency: CPU frequency.
21 - clocks: reference to the clock supplying the EMAC.
23 Child nodes of the driver are the individual PHY devices connected to the
24 MDIO bus. They must have a "reg" property given the PHY address on the MDIO bus.
