[PATCH net-next v2 0/2] net: lan743x: add RMII support for PCI11x1x

From: Thangaraj Samynathan

Date: Tue May 26 2026 - 12:01:43 EST


This series adds RMII interface support for the Microchip PCI11x1x
Ethernet controller.

The PCI11x1x device supports RMII as an alternative MAC-PHY interface,
selected via the STRAP_READ software strap register. Patch 1 reads the
RMII strap bits from this register and sets the is_rmii_en flag. Patch 2
uses this flag to configure the PHY interface mode, phylink supported
interfaces, and enables RMII in hardware via the RMII_CTL register.

Change Log:
===========
v1 -> v2:
- Remove redundant mac_capabilities &= ~MAC_1000FD; phylink already
handles capability reduction for RMII via phy_caps_from_interface()
[patch 2/2]
