okay so bestie, welcome to the Kernel API Manual — this is the page for omap_register_i2c_bus, and we're gonna get you fluent in it, no cap ✨

🌸 NAME 🌸

omap_register_i2c_bus — registers an I2C bus with device descriptors. that's the whole vibe. it sets up the bus and hands over the descriptor info that goes with it 🦋

---

✨ SYNOPSIS ✨

int omap_register_i2c_bus (int bus_id , u32 clkrate , struct
i2c_board_info const *info , unsigned len );

literally the whole signature, character for character, don't come for me 💅

---

🎀 ARGUMENTS 🎀

• bus_id — the bus id, and heads up: it counts from number 1. not zero. one. remember that or you WILL be confused later, iykyk 😭
• clkrate — the clock rate of the bus, measured in kHz. that's kilohertz, bestie, keep the units straight 🫶
• info — a pointer into the I2C device descriptor table, or NULL if you've got nothing to pass. both are valid, she's flexible 💜
• len — the number of descriptors in that table. count them. all of them. 🔥

---

👑 DESCRIPTION 👑

so what does it do? it returns 0 on success, or an error code if things went sideways. that's it. that's the description. short and iconic, honestly 🌟

lowkey the whole function is just "did it work or not" energy — always check that return value, bestie, don't just assume it slayed 💀
