Subject: [PATCH net-next 04/10] net: stmmac: ingenic: convert to use phy_interface
Date: Wed, 17 Sep 2025 16:12:16 +0100	[thread overview]
Message-ID: <E1uytpQ-00000006H2L-2Jzb@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <aMrPpc8oRxqGtVPJ@shell.armlinux.org.uk>

dwmac-ingenic uses only MII, RMII, GMII or RGMII interface modes, none
of which require any kind of conversion between the MAC and external
world. Thus, mac_interface and phy_interface will be the same.

Convert dwmac-ingenic to use phy_interface when determining the
interface mode that the dwmac core should be configured to at reset,
rather than mac_interface.

Also convert the error prints to use phy_modes() and terminate with a
newline so that we get a human readable string rather than a number for
the interface mode.
