💅 ksz_parse_dt_phy_config(9) — a kernel API manual moment 🎀

okay bestie, welcome to the ksz_parse_dt_phy_config(9) page 💖 this is a Kernel API Manual entry, and it's lowkey iconic — it's got arguments, it's got validations, it's got opinions about your device tree. let's get into it ✨

---

🌸 NAME 🌸

ksz_parse_dt_phy_config — parse and validate PHY configuration from DT 🦋

---

✨ SYNOPSIS ✨

int ksz_parse_dt_phy_config (struct ksz_device *dev , struct mii_bus
*bus , struct device_node *mdio_np );

like, that's the whole signature, no cap 💅

---

🎀 ARGUMENTS 🎀

• dev — pointer to the KSZ device structure
• bus — pointer to the MII bus structure
• mdio_np — pointer to the MDIO node in the device tree

---

💜 DESCRIPTION 💜

okay so here's the vibe 🫶 this function parses and validates PHY configurations for each user port defined in the device tree, for a KSZ switch device. it's giving thorough, it's giving responsible main character energy 🌈

it verifies that the phy-handle properties are correctly set, and that the internal PHYs match expected addresses and parent nodes. it's literally doing a vibe check on your whole PHY setup 🔥

if all the validations pass, it sets up the PHY mask in the MII bus. and if something's mismatched or missing? it logs error messages for any mismatches or missing data 😭 so like, it will tell you. not passive-aggressive, just honest.

---

⭐ RETURN ⭐

0 on success, or a negative error code on failure 💀 — simple as that, bestie.
