xemaclite_mdio_read(9)

💖 xemaclite_mdio_read(9) — like, the Kernel API Manual, but make it make sense 🎀

okay so bestie, we're in the Kernel API Manual today and this little function is genuinely iconic for reading one (1) MII management register. lowkey a whole vibe. it's called xemaclite_mdio_read, and yes the name is giving "I read things from the MDIO bus and I'm normal about it."

---

✨ NAME ✨

xemaclite_mdio_read — Read from a given MII management register 🦋

like… that's it. that's the job. it reads. from a register. in the MII management situation. periodt.

---

🌸 SYNOPSIS 🌸

int xemaclite_mdio_read (struct mii_bus *bus , int phy_id , int reg );

look at her go. three arguments, returns an int. no cap, that's the whole signature 💅

---

🎀 ARGUMENTS 🎀

• bus — the mii_bus struct. she's the whole bus, the main character, the infrastructure. show some respect.
• phy_id — the phy address. which phy we're talking to, iykyk.
• reg — register number to read from. literally just. which register. that's the one.

---

💜 DESCRIPTION 💜

okay so here's the tea 🍓:

This function waits till the device is ready to accept a new MDIO request and then writes the phy address to the MDIO Address register and reads data from MDIO Read Data register, when its available.

the way that it waits first?? patience. maturity. main character energy honestly. it does not just barge in and start writing — no, it checks that the device is ready to accept a new MDIO request, and only then does it write the phy_id into the MDIO Address register and pull the data out of the MDIO Read Data register once that data is actually available. slay. 🫶

---

⭐ RETURN ⭐

Value read from the MII management register. that's it. that's the return value. she returns the thing she read. 💖
