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: =========== v2 -> v3: - Update debug log to report selected interface (SGMII/RMII/RGMII) instead of only SGMII enable/disable state [patch 1/2] - Update commit message to document that EEE is disabled by setting lpi_capabilities = 0 [patch 2/2] v1 -> v2: - Remove redundant mac_capabilities &= ~MAC_1000FD; phylink already handles capability reduction for RMII via phy_caps_from_interface() [patch 2/2] Thangaraj Samynathan (2): net: lan743x: add RMII strap status detection for PCI11x1x net: lan743x: add support for RMII interface drivers/net/ethernet/microchip/lan743x_main.c | 29 +++++++++++++++++-- drivers/net/ethernet/microchip/lan743x_main.h | 6 ++++ 2 files changed, 33 insertions(+), 2 deletions(-) -- 2.34.1
