Subject: [PATCH net-next v3 2/3] dt-bindings: ethernet-phy: add MII-Lite phy interface type

From: Kamil Horák (2N) <kamilh@...s.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.
