1 | * STMicroelectronics 10/100/1000 Ethernet driver (GMAC) |
| 2 | ||
| 3 | Required properties: | |
| 84c9f8c4 DN |
4 | - compatible: Should be "snps,dwmac-<ip_version>" "snps,dwmac" |
| 5 | For backwards compatibility: "st,spear600-gmac" is also supported. | |
| 6a228452 SR |
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 | |
| e8f08ee0 | 13 | - phy-mode: See ethernet.txt file in the same directory. |
| 0e076471 SK |
14 | - snps,reset-gpio gpio number for phy reset. |
| 15 | - snps,reset-active-low boolean flag to indicate if phy reset is active low. | |
| 16 | - snps,reset-delays-us is triplet of delays | |
| 17 | The 1st cell is reset pre-delay in micro seconds. | |
| 18 | The 2nd cell is reset pulse in micro seconds. | |
| 19 | The 3rd cell is reset post-delay in micro seconds. | |
| 25c83b5c SK |
20 | - snps,pbl Programmable Burst Length |
| 21 | - snps,fixed-burst Program the DMA to use the fixed burst mode | |
| 22 | - snps,mixed-burst Program the DMA to use the mixed burst mode | |
| e2a240c7 SZ |
23 | - snps,force_thresh_dma_mode Force DMA to use the threshold mode for |
| 24 | both tx and rx | |
| 25 | - snps,force_sf_dma_mode Force DMA to use the Store and Forward | |
| 26 | mode for both tx and rx. This flag is | |
| 27 | ignored if force_thresh_dma_mode is set. | |

28 | |
| 29 | Optional properties: | |
| c5e4ddbd CYT |
30 | - resets: Should contain a phandle to the STMMAC reset signal, if any |
| 31 | - reset-names: Should contain the reset signal name "stmmaceth", if a | |
| 32 | reset phandle is given | |
| e8f08ee0 | 33 | - max-frame-size: See ethernet.txt file in the same directory |
| 50b4af41 DN |
34 | - clocks: If present, the first clock should be the GMAC main clock, |
| 35 | further clocks may be specified in derived bindings. | |
| ae107d06 | 36 | - clock-names: One name for each entry in the clocks property, the |
| 50b4af41 | 37 | first one should be "stmmaceth". |
