| 3 | Required properties: |
| Dinh Nguyen | 84c9f8c4 | 2012-07-18 13:28:26 +0000 | [diff] [blame] | 4 | - compatible: Should be "snps,dwmac-<ip_version>" "snps,dwmac" |
| 5 | For backwards compatibility: "st,spear600-gmac" is also supported. |
| Stefan Roese | 6a22845 | 2012-03-13 04:56:37 +0000 | [diff] [blame] | 6 | - reg: Address and length of the register set for the device |
| 7 | - interrupt-parent: Should be the phandle for the interrupt controller |
| 8 | that services interrupts for this device |
| 9 | - interrupts: Should contain the STMMAC interrupts |
| 10 | - interrupt-names: Should contain the interrupt names "macirq" |
| 11 | "eth_wake_irq" if this interrupt is supported in the "interrupts" |
| 12 | property |
| 13 | - phy-mode: String, operation mode of the PHY interface. |
| 14 | Supported values are: "mii", "rmii", "gmii", "rgmii". |
| Srinivas Kandagatla | 0e07647 | 2013-07-04 10:35:48 +0100 | [diff] [blame] | 15 | - snps,reset-gpio gpio number for phy reset. |
| 16 | - snps,reset-active-low boolean flag to indicate if phy reset is active low. |
| 17 | - snps,reset-delays-us is triplet of delays |
| 18 | The 1st cell is reset pre-delay in micro seconds. |
| 19 | The 2nd cell is reset pulse in micro seconds. |
| 20 | The 3rd cell is reset post-delay in micro seconds. |
| Srinivas Kandagatla | 25c83b5 | 2013-07-04 10:35:41 +0100 | [diff] [blame] | 21 | - snps,pbl Programmable Burst Length |
| 22 | - snps,fixed-burst Program the DMA to use the fixed burst mode |
| 23 | - snps,mixed-burst Program the DMA to use the mixed burst mode |
| Sonic Zhang | e2a240c | 2013-08-28 18:55:39 +0800 | [diff] [blame] | 24 | - snps,force_thresh_dma_mode Force DMA to use the threshold mode for |
| 25 | both tx and rx |
| 26 | - snps,force_sf_dma_mode Force DMA to use the Store and Forward |
| 27 | mode for both tx and rx. This flag is |
| 28 | ignored if force_thresh_dma_mode is set. |
| Stefan Roese | 6a22845 | 2012-03-13 04:56:37 +0000 | [diff] [blame] | 29 | |
| 30 | Optional properties: |
| 31 | - mac-address: 6 bytes, mac address |
| Chen-Yu Tsai | c5e4ddb | 2014-01-17 21:24:41 +0800 | [diff] [blame] | 32 | - resets: Should contain a phandle to the STMMAC reset signal, if any |
| 33 | - reset-names: Should contain the reset signal name "stmmaceth", if a |
| 34 | reset phandle is given |
