| * 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,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 | |
| - 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: Maximum Transfer Unit (IEEE defined MTU), rather | |
| than the maximum frame size. | |
| 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 */ | |
| max-frame-size = <3800>; | |
| phy-mode = "gmii"; | |
| }; |
