💅 typec_retimer_register(9) — Kernel API Manual moment 💅

okay so bestie, we’re in the Kernel API Manual and today’s main character is typec_retimer_register. no cap, this is the glow-up guide to registering a retimer device ✨

✨ NAME ✨

typec_retimer_register — Register a retimer device. periodt. That’s the whole name situation 💖

🌸 SYNOPSIS 🌸

struct typec_retimer * typec_retimer_register (struct device *parent ,
       const struct typec_retimer_desc *desc );

🫶 ARGUMENTS 🫶

• parent — the parent device. literally just the parent device, bestie 🫶
• desc — the retimer description. yes ma’am, that’s the descriptor 💅

🦋 DESCRIPTION 🦋

Some USB Type-C connectors have their physical lines routed through retimers before they reach muxes or host controllers. that’s just the hardware vibe, iykyk.

In some cases (for example: using alternate modes) these retimers need to be reconfigured appropriately. so iconic of them to need a little tune-up 💅

This function registers retimer switches which route and potentially modify the signals on the Type C physical lines enroute to the host controllers. main character energy for the switches, fr fr 🔥
