✨ cdns_i2c_init(9) ✨

okay bestie, welcome to the cdns_i2c_init page from the Kernel API Manual — section 9, obviously, we're doing kernel-internals hours 💅

🌸 NAME 🌸

cdns_i2c_init — literally just controller initialisation, that's the whole vibe 🎀

🦋 SYNOPSIS 🦋

void cdns_i2c_init (struct cdns_i2c *id );

no cap, that's it. one function, one argument, returns nothing (void), main character energy 🫶

💖 ARGUMENTS 💖

• id — the device's private data structure. like, the whole struct the driver keeps its business in. hand it over and let her cook 🍓

🔥 DESCRIPTION 🔥

Initialise the i2c controller. that's the assignment, that's the entire assignment ✨ she takes the controller and gets it set up and ready to go, and then she's done — void, no return value, no drama, no receipts 💀
