This file has moved to snps,dwmac.yaml.
|
||||||
|
|
||||||
Required properties:
|
|
||||||
- compatible: Should be "snps,dwmac-<ip_version>", "snps,dwmac" or
|
|
||||||
"snps,dwxgmac-<ip_version>", "snps,dwxgmac".
|
|
||||||
For backwards compatibility: "st,spear600-gmac" is also supported.
|
|
||||||
- reg: Address and length of the register set for the device
|
|
||||||
- interrupts: Should contain the STMMAC interrupts
|
|
||||||
- interrupt-names: Should contain a list of interrupt names corresponding to
|
|
||||||
the interrupts in the interrupts property, if available.
|
|
||||||
Valid interrupt names are:
|
|
||||||
- "macirq" (combined signal for various interrupt events)
|
|
||||||
- "eth_wake_irq" (the interrupt to manage the remote wake-up packet detection)
|
|
||||||
- "eth_lpi" (the interrupt that occurs when Rx exits the LPI state)
|
|
||||||
- phy-mode: See ethernet.txt file in the same directory.
