45 Disable Atheros AR803X PHYs hibernation mode. If present, indicates
46 that the hardware of PHY will not enter power saving mode when the
47 cable is disconnected. And the RX_CLK always keeps outputting a
48 valid clock.

65 RGMII I/O voltage regulator (see regulator/regulator.yaml).
66
67 The PHY supports RGMII I/O voltages of 1.5V, 1.8V and 2.5V. You can
68 either connect this to the vddio-regulator (1.5V / 1.8V) or the
69 vddh-regulator (2.5V).
