💅 BCMGPIO(4) — bestie edition 🎀

okay so this is a page from the Kernel Interfaces Manual, and we're talking about bcmgpio — the Broadcom BCM283x GPIO controller. yes it's niche. yes it's iconic. let's get into it ✨

🌸 NAME 🌸

bcmgpio — the Broadcom BCM283x GPIO controller, aka the little guy that decides what your pins are gonna be when they grow up 🦋

---

✨ SYNOPSIS ✨

bcmgpio* at fdt?

that's it. that's the whole vibe. one line. slay 💅

💖 DESCRIPTION 💖

so here's the tea ☕ — the bcmgpio driver pulls its pin control data from the device tree, and uses that to pick one of the multiple possible roles available for pins on Broadcom BCM283x and BCM2711 SoCs. like, each pin has options, and this driver is the one doing the choosing. main character energy fr fr 👑

but ngl, it does not provide direct device driver entry points — instead it makes its functions available to other drivers. it's giving backstage crew, not front-of-house. lowkey the most supportive friend in the kernel 🫶
