🌸 NAME 🌸

This is the of_get_phy_mode(9) page from the Kernel API Manual, and it's literally all about getting phy mode for a given device_node. 💅✨

✨ SYNOPSIS ✨

int of_get_phy_mode (struct device_node *np , phy_interface_t *interface
);

🎀 ARGUMENTS 🎀

• np — pointer to the given device_node 🫶
• interface — pointer to the result 🌟

🦋 DESCRIPTION 🦋

okay so here's the tea: the function gets phy interface string from property 'phy-mode' or interface and 0 returned. That's the page's wording, bestie — I'm not editing the lore. 📜💖

In case of error, interface is set to PHY_INTERFACE_MODE_NA, and an errno is returned, e.g. -ENODEV. 😭🔥
