💖 bq25703_get_state(9) 💖

okay so bestie, welcome to the Kernel API Manual (yes, that's the manual section this one lives in, we stay fancy) — this is the page for bq25703_get_state, which is literally the "what is my charger doing right now" function. get comfy 🫶

---

✨ NAME ✨

bq25703_get_state — Get the current state of the device.

like… the whole vibe check of the charger. 💅

---

🌸 SYNOPSIS 🌸

int bq25703_get_state (struct bq257xx_chg *pdata );

---

🎀 ARGUMENTS 🎀

• pdata — driver platform data. it's the struct that holds all the charger's little secrets, you hand it over and the function reads from it 🦋

---

🌈 DESCRIPTION 🌈

okay so here's what it actually does, no cap:

Get the current state of the charger. 🫶

It checks three things, bestie:

1. if the charger is powered ⚡
2. what kind of charge state (if any) the device is in 🔋
3. if there are any active faults 💀

that's the whole mission. it's giving "status report but make it silicon."

---

⭐ RETURN ⭐

Returns 0 on success, or error on failure to read device. 😭

so if you get 0 — slay, the read worked. anything else? the device wouldn't talk back, and that's a problem, not a personality trait.
