💅 yt8521_soft_reset (9) — Kernel API Manual, bestie edition 🎀

okay so you're in the Kernel API Manual and you found yt8521_soft_reset — the function that issues a PHY software reset on the Motorcomm driver. it's a whole vibe, very "hit restart on the hardware energy" ✨ let's get into it.

✨ NAME ✨

yt8521_soft_reset — literally the function you call to issue a PHY software reset 🫶

---

🌸 SYNOPSIS 🌸

int yt8521_soft_reset (struct phy_device *phydev );

that's it. that's the whole signature. short. iconic. slay 💅

---

🦋 ARGUMENTS 🦋

• phydev — a pointer to a struct phy_device. yeah. that's the one. give it a phy device and it's happy 🎀

---

⭐ DESCRIPTION ⭐

the whole deal: it returns 0 or a negative errno code. no cap.

so like — 0 means we good, everything's fine, go off queen 👑. anything negative is an errno code, meaning something went sideways and you should lowkey check it 😭. that's genuinely all the description says, so don't come for me, I'm just the messenger 💀.

ngl this manpage is giving "minimalist". the description is one line. we respect the confidence tho 💜
