PLGPIO(4)

🎀 PLGPIO(4) 🎀

okay bestie, so this is a page from the Kernel Interfaces Manual — section 4, the driver zone 💅 — and it's all about plgpio, the ARM PrimeCell PL061 GPIO controller. tiny page, huge main character energy ✨

🌸 NAME 🌸

plgpio — the ARM PrimeCell PL061 GPIO controller. that's it, that's the whole vibe 🦋

---

✨ SYNOPSIS ✨

plgpio* at fdt?

literally one line, no cap. the * means any instance, and the ? on fdt means any unit number — she's flexible like that 🫶

---

💖 DESCRIPTION 💖

bestie, listen, the plgpio driver supports the ARM PrimeCell PL061 GPIO controller. that's its whole job and she ate 💅

here's the lowkey important part though: she does not provide direct device driver entry points. nope, not her thing. instead she makes her functions available to other drivers — she's the supportive bestie in the group chat, handing out her GPIO abilities so everyone else can shine 🌈👑

• the ARM PrimeCell General Purpose Input/Output (PL011) Technical Reference Manual, ARM DDI 0190 — yes that's a PL011 in the title right there, i'm just the messenger bestie 🙈 the document number ARM DDI 0190 is what you want for the official tea ☕
