* 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.
|
|
- snps,multicast-filter-bins: Number of multicast filter hash bins
|
|
supported by this device instance
|
|
- snps,perfect-filter-entries: Number of perfect filter entries supported
|
|
by this device instance
|
|
|
|
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
|
|
- clocks: If present, the first clock should be the GMAC main clock
|
|
The optional second clock should be peripheral's register interface clock.
|
|
The third optional clock should be the ptp reference clock.
|
|
Further clocks may be specified in derived bindings.
|
|
- clock-names: One name for each entry in the clocks property.
|
|
The first one should be "stmmaceth".
|
|
The optional second one should be "pclk".
|
|
The optional third one should be "clk_ptp_ref".
|
|
- snps,burst_len: The AXI burst lenth value of the AXI BUS MODE register.
|
|
- tx-fifo-depth: See ethernet.txt file in the same directory
|
|
- rx-fifo-depth: See ethernet.txt file in the same directory
|
|
- mdio: with compatible = "snps,dwmac-mdio", create and register mdio bus.
|
