tps65217_reg_read(9)

💅 tps65217_reg_read(9) — the Kernel API Manual, bestie edition 🎀

Okay so picture this: you're deep in the kernel, you're in the tps65217 MFD driver, and you just need one single register value. Not a whole block, not a vibe, just one. That's literally this function. It's a section 9 manpage, it lives in the Kernel API Manual, and it's lowkey iconic for how tiny it is. ✨

🌸 NAME 🌸

tps65217_reg_read — read a single tps65217 register. That's it. That's the whole job. One register, one read, no drama. 🫶

⭐ SYNOPSIS ⭐

int tps65217_reg_read (struct tps65217 *tps , unsigned int reg ,
       unsigned int *val );

Yep, that's the whole signature. Three args, returns an int. Slay. 💅

🦋 ARGUMENTS 🦋

• tps — the device to read from. Like, the tps65217 you're actually talking to. You gotta tell it which one, bestie, it can't read minds. 🙈
• reg — the register to read. Which one? That one. The one you name right here. unsigned int. 🎯
• val — Contians the value. (Yes, that's the original spelling, keeping it exactly as-is, no cap 😭.) This is your unsigned int * — a pointer, so the value comes back to you through it. Iconic out-param behaviour. 🔥

Heads up: val is a pointer (unsigned int *val), so whatever you pass in is where the answer lands. Don't pass garbage, please. 🌈
