bq25703_hw_shutdown(9)

✨ bq25703_hw_shutdown — the shutdown glow-up ✨

So bestie, this one lives in the Kernel API Manual, section 9 (iykyk, that's the kernel interface section 💅). It's a tiny little function with one job: putting the charger chip into low power mode when it's shutting down. Short page, but we're gonna treat it with the respect it deserves 🫶

🌸 NAME 🌸

bq25703_hw_shutdown — the one that sets the registers for shutdown, no cap

---

🎀 SYNOPSIS 🎀

void bq25703_hw_shutdown(struct bq257xx_chg *pdata);

It returns void, so like… it doesn't come back with receipts. It just does the thing 💅

---

🦋 ARGUMENTS 🦋

• pdata — the driver platform data. That's the struct bq257xx_chg * bestie you're handing over. Yes, it's very main character ✨

---

💖 DESCRIPTION 💖

Okay so here's the vibe: this function enables low power mode for the device while it's in shutdown. That's it. That's the whole plot 🎀

No extra drama, no secret behaviour, just turning the power draw all the way down so the chip can chill in low power mode during shutdown. Iconic, honestly 😌

Heads up bestie: the bq25792 twins show up in that list right next to the bq25703 ones — don't mix them up, they are not the same function fr fr 🙈

Okay and finally, the credits moment 🎬 — this page belongs to the ./drivers/power/supply corner of the kernel, dated October 2026, and it's page bq25703_hw_shutdown(9) of the Kernel API Manual. That's a wrap, slay 💜✨
