| * 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 |
| |
| 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"; |
| }; |
