🌸 NAME 🌸

qcpdc — Qualcomm power domain controller

like, that's the whole vibe. it controls power domains. for Qualcomm. no notes. 👑

🎀 SYNOPSIS 🎀

qcpdc* at fdt?

that's it. that's the whole config line. short and iconic, fr fr 💅

🦋 DESCRIPTION 🦋

so the qcpdc driver is the one that provides support for the Qualcomm power domain controller (PDC, if you're on nickname terms with it).

here's the part that lowkey slays: it acts as a "transparent" interrupt controller 💫 and it hands interrupt handlers over to the parent interrupt controller. that's its whole job. it's giving middle-manager energy but in the good way — it doesn't hog the interrupts for itself, it just makes sure they get where they need to go. so thoughtful of it 🫶
