-PHY nodes
-
-Required properties:
-
- - interrupts : interrupt specifier for the sole interrupt.
- - reg : The ID number for the phy, usually a small integer
-
-Optional Properties:
-
-- compatible: Compatible list, may contain
- "ethernet-phy-ieee802.3-c22" or "ethernet-phy-ieee802.3-c45" for
- PHYs that implement IEEE802.3 clause 22 or IEEE802.3 clause 45
- specifications. If neither of these are specified, the default is to
- assume clause 22.
-
- If the PHY reports an incorrect ID (or none at all) then the
- "compatible" list may contain an entry with the correct PHY ID in the
- form: "ethernet-phy-idAAAA.BBBB" where
- AAAA - The value of the 16 bit Phy Identifier 1 register as
- 4 hex digits. This is the chip vendor OUI bits 3:18
- BBBB - The value of the 16 bit Phy Identifier 2 register as
- 4 hex digits. This is the chip vendor OUI bits 19:24,
- followed by 10 bits of a vendor specific ID.
-
- The compatible list should not contain other values than those
- listed here.
-
-- max-speed: Maximum PHY supported speed (10, 100, 1000...)
-
-- broken-turn-around: If set, indicates the PHY device does not correctly
- release the turn around line low at the end of a MDIO transaction.
-
-- enet-phy-lane-swap: If set, indicates the PHY will swap the TX/RX lanes to
- compensate for the board being designed with the lanes swapped.
-
-- enet-phy-lane-no-swap: If set, indicates that PHY will disable swap of the
- TX/RX lanes. This property allows the PHY to work correcly after e.g. wrong
- bootstrap configuration caused by issues in PCB layout design.
-
-- eee-broken-100tx:
-- eee-broken-1000t:
-- eee-broken-10gt:
-- eee-broken-1000kx:
-- eee-broken-10gkx4:
-- eee-broken-10gkr:
- Mark the corresponding energy efficient ethernet mode as broken and
- request the ethernet to stop advertising it.
-
-- phy-is-integrated: If set, indicates that the PHY is integrated into the same
- physical package as the Ethernet MAC. If needed, muxers should be configured
- to ensure the integrated PHY is used. The absence of this property indicates
- the muxers should be configured so that the external PHY is used.
-
-- resets: The reset-controller phandle and specifier for the PHY reset signal.
-
-- reset-names: Must be "phy" for the PHY reset signal.
-
-- reset-gpios: The GPIO phandle and specifier for the PHY reset signal.
-
-- reset-assert-us: Delay after the reset was asserted in microseconds.
- If this property is missing the delay will be skipped.
-
-- reset-deassert-us: Delay after the reset was deasserted in microseconds.
- If this property is missing the delay will be skipped.
