STRUCT PHY_PROVIDER(9)

💅 struct phy_provider(9)

okay bestie, buckle up — we're deep in the Kernel API Manual today and this one is genuinely iconic. this is the page for struct phy_provider, and it does exactly what it says on the tin: it represents the phy provider. that's it, that's the whole vibe. periodt. 🎀

✨ NAME ✨

struct phy_provider — literally just the struct that represents the phy provider 🦋

---

🌸 SYNOPSIS 🌸

here's the whole glow-up, copy-pasted exactly so nobody comes for me:

struct phy_provider {
    struct device           *dev;
    struct device_node      *children;
    struct module           *owner;
    struct list_head        list;
    struct phy * (*of_xlate)(struct device *dev, const struct of_phandle_args *args);
};

no cap, that's the entire thing. five fields. she's compact, she's efficient, she ate. 💅

👑 Members 👑

let's go field by field, i got you:

• dev — the phy provider device. this is the device herself, the main character energy of the whole struct. ⭐
• children — can be used to override the default (dev->of_node) child node. so if the default child node isn't giving what it needs to give, this is your escape hatch. 🙈
• owner — the module owner having of_xlate. basically whoever's holding the keys to that function. 🔑
• list — to maintain a linked list of PHY providers. all the providers holding hands in a nice little chain, we love a support system. 🫶
• of_xlate — function pointer to obtain phy instance from phy pointer. yes bestie, a function pointer, we're being fancy today. it takes struct device *dev and const struct of_phandle_args *args and hands you back a struct phy *. iykyk. ✨

ngl, if you're poking around in here you're probably writing a PHY driver. good luck, you're doing amazing, drink some water. 🍓

and that's the whole page, bestie! this little beauty lives in ./include/linux/phy, and this edition is dated October 2026, slaying under the name struct phy_provider(9). mwah, go build something iconic 💖🧚
