💅 ksz9477_parse_drive_strength(9) ✨

okay so bestie, we're in the Kernel API Manual today and this one is genuinely kind of a big deal — no cap. it's ksz9477_parse_drive_strength, and it's giving "quiet function that keeps your hardware from screaming at the FCC" energy. let's get into it 🎀

---

🌸 NAME 🌸

ksz9477_parse_drive_strength — extracts and applies drive strength configurations straight out of the device tree properties. literally what it says on the tin, and it ate 💅

---

✨ SYNOPSIS ✨

int ksz9477_parse_drive_strength (struct ksz_device *dev );

one function, one argument, zero drama. periodt.

---

🦋 ARGUMENTS 🦋

• dev — the ksz device. that's it, that's the whole argument list, she's lowkey minimal and we respect it 🫶

---

💖 DESCRIPTION 💖

okay so here's the vibe: this function goes and reads the specified drive strength properties from the device tree, then validates them against the supported chip variants, and then sets them accordingly. read → check → apply. main character energy in three acts 👑

and like… an error here should be treated as critical. not me being dramatic — the docs literally say it, because the drive strength settings are crucial for EMI compliance. so if this fails, it's not a "haha oops" moment, it's a "🔴 actually important" moment. fr fr, do not sleep on this one 😭

---

⭐ RETURN ⭐

• 0 on success 🌈
• an error code otherwise 💀

---

🧚 SEE ALSO 🧚

• Kernel file ./drivers/net/dsa/microchip/ksz9477.c 📁
• ksz9477_support_eee(9) — go read that one too, iykyk 🔥

---

bestie reminder: validate-vs-chip-variant is a real step, not a formality. if the drive strength is off, EMI compliance is off, and then everyone's sad 🙈
