- enum: [ 0, 1, 2 ]
qca,keep-pll-enabled:
description: |
If set, keep the PLL enabled even if there is no link. Useful if you
want to use the clock output without an ethernet link.
Only supported on the AR8031.
type: boolean
vddio-supply:
description: |
RGMII I/O voltage regulator (see regulator/regulator.yaml).
The PHY supports RGMII I/O voltages of 1.5V, 1.8V and 2.5V. You can
either connect this to the vddio-regulator (1.5V / 1.8V) or the
vddh-regulator (2.5V).
Only supported on the AR8031.
vddio-regulator:
type: object
description:
Initial data for the VDDIO regulator. Set this to 1.5V or 1.8V.
allOf:
- $ref: /schemas/regulator/regulator.yaml
vddh-regulator:
type: object
description:
Dummy subnode to model the external connection of the PHY VDDH
regulator to VDDIO.
