89 broken-turn-around:
92 If set, indicates the PHY device does not correctly release
96 brr-mode:
100 defined in the BroadR-Reach link mode specification under 1BR-100 and
101 1BR-10 names. The PHY must be configured to operate in BroadR-Reach mode
107 External clock connected to the PHY. If not specified it is assumed
108 that the PHY uses a fixed crystal or an internal oscillator.
110 enet-phy-lane-swap:
113 If set, indicates the PHY will swap the TX/RX lanes to
117 enet-phy-lane-no-swap:
120 If set, indicates that PHY will disable swap of the
121 TX/RX lanes. This property allows the PHY to work correctly after

169 Specifies the timing role of the PHY in the network link. This property is
173 It is applicable to Single Pair Ethernet (1000/100/10Base-T1) and other
174 PHY types, including 1000Base-T, where it controls whether the PHY should
177 - 'forced-master': The PHY is forced to operate as a master.
178 - 'forced-slave': The PHY is forced to operate as a slave.
179 - 'preferred-master': Prefer the PHY to be master but allow negotiation.
180 - 'preferred-slave': Prefer the PHY to be slave but allow negotiation.

191 If set, indicates that the PHY is integrated into the same

195 should be configured so that the external PHY is used.
200 reset-names:
201 const: phy
203 reset-gpios:
206 The GPIO phandle and specifier for the PHY reset signal.
208 reset-assert-us:
213 reset-deassert-us:
223 rx-internal-delay-ps:
225 RGMII Receive PHY Clock Delay defined in pico seconds. This is used for
226 PHY's that have configurable RX internal delays. If this property is
227 present then the PHY applies the RX delay.
229 tx-internal-delay-ps:
231 RGMII Transmit PHY Clock Delay defined in pico seconds. This is used for
232 PHY's that have configurable TX internal delays. If this property is
233 present then the PHY applies the TX delay.
