bq25792_read16(9)

💖 bq25792_read16 — the "just read the register bestie" page 💖

okay so you found the Kernel API Manual page for bq25792_read16(9) and honestly? it's a little cutie. it does exactly one thing and it does it slayfully. let's get into it 🫶

---

✨ NAME ✨

bq25792_read16 — Read a 16-bit value from device register

that's it. that's the whole job. iconic behavior, zero notes 💅

---

🌸 SYNOPSIS 🌸

int bq25792_read16 (struct bq257xx_chg *pdata , unsigned int reg , u16
*val );

like, look at her. four things and a return type. a whole vibe ✨

---

🎀 ARGUMENTS 🎀

bestie you gotta pass all three or it's not gonna work, no cap:

• pdata — the driver platform data 🫶 this is your struct bq257xx_chg * and she's carrying everything the driver needs to know about herself.
• reg — the register address you're reading from 📍 like, which little slot in the chip are we peeking at today.
• val — pointer to store the register value 💌 it's a u16 *, and this is where the answer lands once the read goes through.

---

💜 DESCRIPTION 💜

so here's the tea: bq25792_read16 reads a 16-bit big-endian value from the BQ25792 device via regmap, and then converts it to CPU byte order for you. 🧚

that's the whole flow — grab the raw big-endian bytes from the chip, hand them back in whatever byte order your CPU actually speaks. the conversion is the main character here, ok? the way that endianness would otherwise ruin your entire day 😭

---

🔥 RETURN 🔥

• returns 0 on success ⭐
• returns error on failure to read 💀

so like, check the return value. please. for me. 🙈

k bye, go read some registers bestie 💅✨🍓
