This patch is an attempt to gather the Ethernet related bindings in one file, like it's done in the MMC and some other subsystems. It should save some of the trouble of documenting several properties over and over in each binding document, instead only making reference to the main file. I have used the Embedded Power Architecture(TM) Platform Requirements (ePAPR) standard as a base for the properties description, also documenting some ad-hoc properties that have been introduced over time despite having direct analogs in ePAPR.

* 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: See ethernet.txt file in the same directory.
|
|
- 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:
|
|
- 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
|
|
- max-frame-size: See ethernet.txt file in the same directory
|
|
|
|
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 */
|
|
max-frame-size = <3800>;
|
|
phy-mode = "gmii";
|
|
};
