✨ bq25792_set_chrg_volt(9) ✨

okay so bestie, we're in the Kernel API Manual today and this page is literally all about bq25792_set_chrg_volt — one little function, one big job. buckle up 🎀

🌸 NAME 🌸

bq25792_set_chrg_volt — Set the maximum charge voltage

like, that's it. that's the whole vibe. it sets the max charge voltage. 💅

---

🦋 SYNOPSIS 🦋

int bq25792_set_chrg_volt (struct bq257xx_chg *pdata , int vbat );

no cap, that's the signature. don't @ me.

---

💖 ARGUMENTS 💖

• pdata — the driver platform data. it's giving "the whole charger situation" energy. this is the struct you're passing in 🫶
• vbat — the voltage value to set, in uV (microvolts, bestie, tiny tiny units ⚡). this is your requested charge voltage.

---

🌈 DESCRIPTION 🌈

ok so what actually happens: it sets the maximum charge voltage by clamping the value you asked for between the device limits, and then writes that to the appropriate register.

so like — if you ask for something unhinged, the device says "no babe, we're doing this in range" and clamps it. then it goes to the register. iconic behavior honestly 👑

---

🔥 RETURN 🔥

Returns 0 on success, or an error on failure to write. that's it. zero is the slay. anything else means the write did not go through 😭

reminder bestie: vbat is in uV, not mV, not V. do not come in here with the wrong units, i'm begging 🙈
