From: Russell King (Oracle) Date: Mon, 3 Nov 2025 11:50:10 +0000 (+0000) Subject: net: stmmac: add stmmac_get_phy_intf_sel() X-Git-Tag: v6.19-rc1~170^2~246^2~7 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b459790d3fd6d7ead31182ae0cd8632fe79deed6;p=thirdparty%2Fkernel%2Flinux.git net: stmmac: add stmmac_get_phy_intf_sel() Provide a function to translate the PHY interface mode to the phy_intf_sel pin configuration for dwmac1000 and dwmac4 cores that support multiple interfaces. We currently handle MII, GMII, RGMII, SGMII, RMII and REVMII, but not TBI, RTBI nor SMII as drivers do not appear to use these three and the driver doesn't currently support these.
