* 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"
- 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
