pch_i2c_func(9)

💅 pch_i2c_func(9) — like, the Kernel API Manual page you didn't know you needed

okay so bestie, welcome to pch_i2c_func(9) from the Kernel API Manual — yes this is a real kernel function page and yes it's basically one line of code with a whole personality. let's get into it 🎀

---

✨ NAME ✨

pch_i2c_func — it returns the functionality of the I2C driver. that's it. that's the whole job. iconic honestly 👑

---

🌸 SYNOPSIS 🌸

u32 pch_i2c_func (struct i2c_adapter *adap );

like, you hand it an adapter and it hands you back a u32 full of functionality bits. transactional. slay 💖

---

🦋 ARGUMENTS 🦋

• adap — pointer to struct i2c_algo_pch_data. so not just any adapter bestie, it's specifically the PCH one. read the name, love the name 🌈

---

🔥 SEE ALSO 🔥

so there's a whole friend group here and you should lowkey meet all of them 🫶

the kernel file is ./drivers/i2c/busses/i2c-eg20t.c, and it's giving main character energy for these structs and functions:

• struct i2c_algo_pch_data(9)
• struct adapter_info(9)
• pch_i2c_init(9)
• pch_i2c_wait_for_bus_idle(9)
• pch_i2c_start(9)
• pch_i2c_stop(9)
• pch_i2c_repstart(9)
• pch_i2c_writebytes(9)
• pch_i2c_sendack(9)
• pch_i2c_sendnack(9)
• pch_i2c_restart(9)
• pch_i2c_readbytes(9)
• pch_i2c_cb(9)
• pch_i2c_handler(9)
• pch_i2c_xfer(9)
• pch_i2c_disbl_int(9)

fr fr go read them, they're all in ./drivers/i2c/busses/ and they're all part of the same saga 💀

<div>ok that's the page!! this gem came out of ./drivers/i2c/busses, October 2026, and it lives as pch_i2c_func(9) forever. mwah 💜✨</div>
