1 | * AMD 10GbE PHY driver (amd-xgbe-phy) |
| 2 | ||
| 3 | Required properties: | |
| 4 | - compatible: Should be "amd,xgbe-phy-seattle-v1a" and | |
| 5 | "ethernet-phy-ieee802.3-c45" | |
| 6 | - reg: Address and length of the register sets for the device | |
| 7 | - SerDes Rx/Tx registers | |
| 8 | - SerDes integration registers (1/2) | |
| 9 | - SerDes integration registers (2/2) | |
| c3152d47 LT |
10 | - interrupt-parent: Should be the phandle for the interrupt controller |
| 11 | that services interrupts for this device | |
| 12 | - interrupts: Should contain the amd-xgbe-phy interrupt. | |

14 | Optional properties: |
| 15 | - amd,speed-set: Speed capabilities of the device | |
| 16 | 0 - 1GbE and 10GbE (default) | |
| 17 | 1 - 2.5GbE and 10GbE | |
| 18 | ||

19 | The following optional properties are represented by an array with each |
| 20 | value corresponding to a particular speed. The first array value represents | |
| 21 | the setting for the 1GbE speed, the second value for the 2.5GbE speed and | |
| 22 | the third value for the 10GbE speed. All three values are required if the | |
| 23 | property is used. | |
| 24 | - amd,serdes-blwc: Baseline wandering correction enablement | |
| 25 | 0 - Off | |
| 26 | 1 - On | |
| 27 | - amd,serdes-cdr-rate: CDR rate speed selection | |
| 28 | - amd,serdes-pq-skew: PQ (data sampling) skew | |
| 29 | - amd,serdes-tx-amp: TX amplitude boost | |
| 74ad7524 TL |
30 | - amd,serdes-dfe-tap-config: DFE taps available to run |
| 31 | - amd,serdes-dfe-tap-enable: DFE taps to enable | |
