fwnode_typec_mux_get(9) 🦋

okay so bestie, this page lives in the Kernel API Manual — yes, that one — and today’s main character is the USB Type-C multiplexer lookup function. it’s giving “find my mux” energy, no cap ✨

🎀 NAME 🎀

fwnode_typec_mux_get — Find USB Type-C Multiplexer

✨ SYNOPSIS ✨

struct typec_mux * fwnode_typec_mux_get (struct fwnode_handle *fwnode );

🌸 ARGUMENTS 🌸

• fwnode — The caller device node. that’s the one, bestie 🫶

💖 DESCRIPTION 💖

Okay so this function finds a mux linked to the caller. It’s primarily meant for the Type-C drivers — iykyk, that’s literally their lane 💅

On success it returns a reference to the mux. If no matching connection was found, it returns NULL. And if a connection was found but the mux has not been enumerated yet, it returns ERR_PTR(-EPROBE_DEFER) — literally the “not yet, babes” signal 😭🔥
