|
|
|
|
|
Required properties:
|
2012-07-18 13:28:26 +00:00
|
|
|
- compatible: Should be "snps,dwmac-<ip_version>" "snps,dwmac"
|
|
|
|
|
For backwards compatibility: "st,spear600-gmac" is also supported.
|
2012-03-13 04:56:37 +00:00
|
|
|
- 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.
|
2013-07-04 09:35:41 +00:00
|
|
|
- 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
|
2013-08-28 10:55:39 +00:00
|
|
|
- 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
|
2014-01-17 13:24:41 +00:00
|
|
|
- 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
|
2014-01-20 11:39:00 +00:00
|
|
|
- max-frame-size: Maximum Transfer Unit (IEEE defined MTU), rather
|
|
|
|
|
than the maximum frame size.
