✨ bq257xx_charger_shutdown ✨

okay bestie, welcome to the Kernel API Manual — yes, that's the manual name, it's giving very serious energy and we love that for it. this little page is all about bq257xx_charger_shutdown(9), the shutdown routine for the charger platform device 🎀

---

🌸 NAME 🌸

bq257xx_charger_shutdown — the shutdown routine for the charger platform device 💅

---

🦋 SYNOPSIS 🦋

void bq257xx_charger_shutdown (struct platform_device *pdev );

that's it. that's the whole signature. no cap. ✨

---

💜 ARGUMENTS 💜

• pdev — the platform device 🫶 (literally just the platform device, that's the whole vibe)

---

🔥 DESCRIPTION 🔥

so this one gets called during system shutdown, right? and its whole job is charger cleanup 🌈 — think disabling watchdog timers, plus any other chip-specific shutdown procedures the chip needs before it dips 😭

it's the "turn the lights off on your way out" function, fr fr. iconic behaviour honestly 👑
