The snps,phy-addr device tree property is non-standard, and should be removed in favor of proper phy node support. Remove it from the binding documents and warn if the property is still used. Most PHYs respond to address 0, but a few don't, so auto-detect PHY address by default, to make up for the lack of explicit address selection.

* STMicroelectronics 10/100/1000 Ethernet driver (GMAC)
|
|
|
|
Required properties:
|
|
- 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
|
|
- interrupts: Should contain the STMMAC interrupts
|
|
- interrupt-names: Should contain the interrupt names "macirq"
|
|
"eth_wake_irq" if this interrupt is supported in the "interrupts"
|
|
property
|
|
- phy-mode: String, operation mode of the PHY interface.
|
|
Supported values are: "mii", "rmii", "gmii", "rgmii".
|
|
- snps,reset-gpio gpio number for phy reset.
|
|
- snps,reset-active-low boolean flag to indicate if phy reset is active low.
|
|
- snps,reset-delays-us is triplet of delays
|
|
The 1st cell is reset pre-delay in micro seconds.
|
|
The 2nd cell is reset pulse in micro seconds.
|
|
The 3rd cell is reset post-delay in micro seconds.
|
|
- snps,pbl Programmable Burst Length
|
|
- snps,fixed-burst Program the DMA to use the fixed burst mode
|
|
- snps,mixed-burst Program the DMA to use the mixed burst mode
|
|
- snps,force_thresh_dma_mode Force DMA to use the threshold mode for
|
|
both tx and rx
|
|
- snps,force_sf_dma_mode Force DMA to use the Store and Forward
|
|
mode for both tx and rx. This flag is
|
|
ignored if force_thresh_dma_mode is set.
|
|
|
|
Optional properties:
|
|
- mac-address: 6 bytes, mac address
|
|
- resets: Should contain a phandle to the STMMAC reset signal, if any
|
|
- reset-names: Should contain the reset signal name "stmmaceth", if a
|
|
reset phandle is given
|
|
|
|
Examples:
|
|
|
|
gmac0: ethernet@e0800000 {
|
|
compatible = "st,spear600-gmac";
|
|
reg = <0xe0800000 0x8000>;
|
|
interrupt-parent = <&vic1>;
|
|
interrupts = <24 23>;
|
|
interrupt-names = "macirq", "eth_wake_irq";
|
|
mac-address = [000000000000]; /* Filled in by U-Boot */
|
|
phy-mode = "gmii";
|
|
};
