phylink_of_phy_connect(9)

✨ NAME ✨

phylink_of_phy_connect — bestie, this is the one that connects the PHY that's specified in the DT node 💅

(also hi, you're reading the Kernel API Manual, welcome to the group chat 🫶)

---

🌸 SYNOPSIS 🌸

int phylink_of_phy_connect (struct phylink *pl , struct device_node *dn
, u32 flags );

🎀 ARGUMENTS 🎀

• pl — a pointer to a struct phylink that you got back from phylink_create. like, the phylink instance you're doing all this for ✨
• dn — a pointer to a struct device_node. yes, the device tree one 🦋
• flags — PHY-specific flags that get communicated to the PHY device driver. very "here's a little note for the PHY driver" energy 💌

---

💖 DESCRIPTION 💖

okay so here's the vibe: this function connects the PHY that's specified in the device node dn to the phylink instance specified by pl. simple, iconic, no cap 💅

and the actions specified in phylink_connect_phy will be performed — so it's not just sitting there looking cute, it's actually doing the whole connect routine 🔥

returns 0 on success, or a negative errno if things went sideways 😭

ngl, always check that return value bestie. negative errno means it did NOT slay.
