Subject: [PATCH net v2 2/4] dt-bindings: ethernet-phy: add MII-Lite phy interface type
Date: Fri, 27 Jun 2025 13:23:04 +0200 [thread overview]
Message-ID: <20250627112306.1191223-3-kamilh@axis.com> (raw)
In-Reply-To: <20250627112306.1191223-1-kamilh@axis.com>
Some Broadcom PHYs are capable to operate in simplified MII mode,
without TXER, RXER, CRS and COL signals as defined for the MII.
The MII-Lite mode can be used on most Ethernet controllers with full
MII interface by just leaving the input signals (RXER, CRS, COL)
inactive. The absence of COL signal makes half-duplex link modes
impossible but does not interfere with BroadR-Reach link modes on
Broadcom PHYs, because they are all full-duplex only.
Add new interface type "mii-lite" to phy-connection-type enum.
