✨ QCGPIO 💅

okay bestie, welcome to the qcgpio page — it lives in section 4 of the kernel interfaces manual, so you already know it's gonna be a hardware moment 🎀

🌸 NAME 🌸

qcgpio — the Qualcomm Snapdragon GPIO controller, no cap 👑

🦋 SYNOPSIS 🦋

qcgpio* at acpi?
qcgpio* at fdt?

literally just those two lines and honestly? iconic. it attaches either at acpi? or at fdt? — pick your fighter 💅

✨ DESCRIPTION ✨

so the qcgpio driver is the one that provides support for the GPIO controller that's found on Qualcomm Snapdragon SoCs 🔥 that's the whole vibe, fr fr.

here's the thing though — it does not provide direct device driver entry points 🫶 like, it's not out here handing you functions to call willy-nilly. instead it makes its functions available to acpi(4). that's the arrangement. that's the situation. iykyk 💖

ngl it's giving "supporting character with main character energy" — it's not on stage, but nothing works without it 😭

🌈 SEE ALSO 🌈
