phy_modes(9)

✨ NAME ✨

okay so bestie, welcome to phy_modes(9) from the Kernel API Manual! This is the page for phy_modes — the cutie that maps the phy_interface_t enum to the device tree binding of phy-mode. 🎀

🦋 SYNOPSIS 🦋

const char * phy_modes (phy_interface_t interface );

🎀 ARGUMENTS 🎀

• interface — an enum phy_interface_t value. that's the arg, bestie, no cap. 💅

🌸 DESCRIPTION 🌸

okay so here's the tea: phy_modes maps the phy_interface_t enum defined in this file into the device tree binding of 'phy-mode', so that an Ethernet device driver can get the PHY interface from device tree. literally making enum-to-device-tree communication happen. ✨
