BCMSTBGPIO(4)

💅 BCMSTBGPIO(4) — okay bestie, let's talk GPIOs

So this is a page from the Kernel Interfaces Manual (yes, the 4 section, the driver one, iykyk) and it's all about bcmstbgpio, the Broadcom Set-top Box GPIO controller. Buckle up, it's short but it ate. ✨

🌸 NAME 🌸

bcmstbgpio — the Broadcom Set-top Box GPIO controller, periodt. 💅

---

🦋 SYNOPSIS 🦋

bcmstbgpio* at fdt?

That's literally it. The * means "any unit number, we don't gatekeep," and the ? after fdt means the attachment is optional-ish vibes. 🎀

💖 DESCRIPTION 💖

okay so the bcmstbgpio driver is the main character when it comes to giving you support for the GPIO ports found on Broadcom Set-top Box SoCs. 🫶

And like, this includes the Broadcom BCM2712 SoC — the exact one that's living its best life inside the Raspberry Pi 5. 🔥 Yes, that Raspberry Pi 5. Iconic.

Now, important detail bestie: it does not provide direct device driver entry points. Nope, none of that. Instead it makes its functions available to other drivers. It's giving supportive bestie energy — it doesn't want the spotlight, it just wants everyone else to slay. 😭💜

lowkey reminder: this page came from the Debian build, dated August 9, 2025 — so if you're citing it in your group chat, that's the receipt, bestie. 📅💅
