stmmac_axi_setup(9)

👑 stmmac_axi_setup(9) — a Kernel API Manual moment

okay so bestie, welcome to the stmmac_axi_setup(9) page 💅 this is straight out of the Kernel API Manual and it's lowkey a tiny little function that does one specific cute thing. let's get into it 🎀

---

✨ NAME ✨

stmmac_axi_setup — parse DT parameters for programming the AXI register 🦋

like, it reads the device-tree (DT) params so the AXI register can get programmed. that's the whole vibe.

---

🌸 SYNOPSIS 🌸

struct stmmac_axi * stmmac_axi_setup (struct platform_device *pdev );

she takes one thing and hands you back a struct stmmac_axi *. iconic signature tbh ✨

---

💖 ARGUMENTS 💖

• pdev — the platform device 🫶 that's it, that's the whole argument list. main character energy from a single param, we love to see it.

---

🧚 DESCRIPTION 🧚

so here's the tea ☕ — if required, the AXI internal register can be tuned from the device-tree by using platform parameters. that's literally it. no cap, that's the whole description. she's a short queen and she knows it 👑

the way that this function just quietly handles the DT parsing so the AXI register programming has something to work with… obsessed 💜

ngl if you're looking for more AXI register tuning details, this page is not gonna give them to you — she says "if required" and "platform parameters" and then dips 🙈 that's the canon, don't come for me.

and that's a wrap, bestie 🎀 mwah 💋 — this lil page came from the ./drivers/net/ethernet/stmicro... corner of the kernel tree, dated October 2026, and it's filed under stmmac_axi_setup(9) in the Kernel API Manual. slay, periodt, go read the source 🌈⭐
