| * AMD 10GbE PHY driver (amd-xgbe-phy) |
| |
| Required properties: |
| - compatible: Should be "amd,xgbe-phy-seattle-v1a" and |
| "ethernet-phy-ieee802.3-c45" |
| - reg: Address and length of the register sets for the device |
| - SerDes Rx/Tx registers |
| - SerDes integration registers (1/2) |
| - SerDes integration registers (2/2) |
| - interrupt-parent: Should be the phandle for the interrupt controller |
| that services interrupts for this device |
| - interrupts: Should contain the amd-xgbe-phy interrupt. |
| |
| Optional properties: |
| - amd,speed-set: Speed capabilities of the device |
| 0 - 1GbE and 10GbE (default) |
| 1 - 2.5GbE and 10GbE |
| |
| The following optional properties are represented by an array with each |
| value corresponding to a particular speed. The first array value represents |
| the setting for the 1GbE speed, the second value for the 2.5GbE speed and |
| the third value for the 10GbE speed. All three values are required if the |
| property is used. |
| - amd,serdes-blwc: Baseline wandering correction enablement |
| 0 - Off |
| 1 - On |
| - amd,serdes-cdr-rate: CDR rate speed selection |
| - amd,serdes-pq-skew: PQ (data sampling) skew |
| - amd,serdes-tx-amp: TX amplitude boost |
| - amd,serdes-dfe-tap-config: DFE taps available to run |
| - amd,serdes-dfe-tap-enable: DFE taps to enable |
| |

| xgbe_phy@e1240800 { |
| compatible = "amd,xgbe-phy-seattle-v1a", "ethernet-phy-ieee802.3-c45"; |
