regmap_init_i2c(9)

🎀 NAME 🎀

Okay bestie, this is regmap_init_i2c(9) from the Kernel API Manual, and it is literally here to do one iconic thing: Initialise register map.

So the name vibe is: regmap_init_i2c — Initialise register map. That’s it, that’s the whole name, and it ate. 💅

---

✨ SYNOPSIS ✨

The signature is exactly this, no cap:

regmap_init_i2c (i2c , config );

---

🌸 ARGUMENTS 🌸

• i2c — Device that will be interacted with. That’s the device bestie, periodt.
• config — Configuration for register map. The config for the register map, fr fr.

---

💅 DESCRIPTION 💅

This part is short and sweet, so listen up: the return value will be an ERR_PTR on error or a valid pointer to a struct regmap.

That’s the whole description, and honestly? Iconic minimalism. ✨
