- * 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,phy-addr phy address to connect to.
- - 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
- 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";
- };
