💅 yt8521_adjust_status(9) 💅

okay so this is a page straight out of the Kernel API Manual, and we're talking about yt8521_adjust_status — the little function that updates speed and duplex onto phydev, and when you're in fiber mode? yeah, it adjusts speed and duplex there too. slay. 🧚

---

✨ NAME ✨

yt8521_adjust_status — update speed and duplex to phydev. when in fiber mode, adjust speed and duplex. no cap, that's literally the whole job description bestie 🫶

---

🌸 SYNOPSIS 🌸

int yt8521_adjust_status (struct phy_device *phydev , int status , bool
is_utp );

like, it returns an int and takes three things. iconic signature tbh 💖

---

🎀 ARGUMENTS 🎀

• phydev — a pointer to a struct phy_device. yes, that phydev. the main character of the whole file 🌟
• status — the yt8521 status read from YTPHY_SPECIFIC_STATUS_REG. it comes pre-read, you don't gotta go get it yourself 💅
• is_utp — either false (yt8521 work in fiber mode) or true (yt8521 work in utp mode). pick your vibe, bestie, but pick correctly 🦋

---

⚠️ NOTE ⚠️

The caller must have taken the MDIO bus lock. fr fr, do not skip this one — lock first, then call. no exceptions 🙈

and it returns 0. that's it. that's the return value 🎀
