regmap_get_max_register(9)

hey bestie 💖 you’re on the regmap_get_max_register(9) page in the Kernel API Manual, and it’s giving “small but important regmap helper” energy. no cap.

🌸 NAME 🌸

regmap_get_max_register — Report the max register value. That’s the whole assignment, periodt. 💅

✨ SYNOPSIS ✨

int regmap_get_max_register (struct regmap *map );

🎀 ARGUMENTS 🎀

• map — the register map to operate on. This is the regmap you’re asking about, bestie.

🦋 DESCRIPTION 🦋

This function reports the max register value. It’s mainly intended for use by generic infrastructure built on top of regmap — like the reusable plumbing bestie, iykyk. It’s not trying to be extra; it just reports that max-register value.
