| Simon Glass | a71fa3f | 2015-04-05 16:07:35 -0600 | [diff] [blame] | 1 | * STMicroelectronics 10/100/1000 Ethernet driver (GMAC) |
| 2 | |
| 3 | Required properties: |
| 4 | - compatible: Should be "snps,dwmac-<ip_version>" "snps,dwmac" |
| 5 | For backwards compatibility: "st,spear600-gmac" is also supported. |
| 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: See ethernet.txt file in the same directory. |
| 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. |
| 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 |
| 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 | - snps,multicast-filter-bins: Number of multicast filter hash bins |
| 29 | supported by this device instance |
| 30 | - snps,perfect-filter-entries: Number of perfect filter entries supported |
| 31 | by this device instance |
| 32 | |
| 33 | Optional properties: |
| 34 | - resets: Should contain a phandle to the STMMAC reset signal, if any |
| 35 | - reset-names: Should contain the reset signal name "stmmaceth", if a |
| 36 | reset phandle is given |
| 37 | - max-frame-size: See ethernet.txt file in the same directory |
| 38 | - clocks: If present, the first clock should be the GMAC main clock, |
| 39 | further clocks may be specified in derived bindings. |
| 40 | - clock-names: One name for each entry in the clocks property, the |
| 41 | first one should be "stmmaceth". |
| 42 | - clk_ptp_ref: this is the PTP reference clock; in case of the PTP is |
| 43 | available this clock is used for programming the Timestamp Addend Register. |
| 44 | If not passed then the system clock will be used and this is fine on some |
| 45 | platforms. |
| 46 | - snps,burst_len: The AXI burst lenth value of the AXI BUS MODE register. |
| 47 | |
| 48 | Examples: |
| 49 | |
| 50 | gmac0: ethernet@e0800000 { |
| 51 | compatible = "st,spear600-gmac"; |
| 52 | reg = <0xe0800000 0x8000>; |
| 53 | interrupt-parent = <&vic1>; |
| 54 | interrupts = <24 23>; |
| 55 | interrupt-names = "macirq", "eth_wake_irq"; |
| 56 | mac-address = [000000000000]; /* Filled in by U-Boot */ |
| 57 | max-frame-size = <3800>; |
| 58 | phy-mode = "gmii"; |
| 59 | snps,multicast-filter-bins = <256>; |
| 60 | snps,perfect-filter-entries = <128>; |
| 61 | clocks = <&clock>; |
| 62 | clock-names = "stmmaceth"; |
| 63 | }; |
