💅 ptp_find_pin_unlocked(9) — Kernel API Manual 💅

okay bestie, welcome to the Kernel API Manual page for ptp_find_pin_unlocked(9) ✨ This one is a tiny wrapper situation, and the vibe is very “read the description before you call me” 🎀

---

🌸 NAME 🌸

ptp_find_pin_unlocked — wrapper for ptp_find_pin()

🦋 SYNOPSIS 🦋

int ptp_find_pin_unlocked (struct ptp_clock *ptp , enum ptp_pin_function
       func , unsigned int chan );

💖 ARGUMENTS 💖

• ptp — the clock you got from ptp_clock_register. That’s your clock bestie 🕰️
• func — one of the ptp_pin_function enumerated values. Pick from the enum, no freestyle 💅
• chan — the particular functional channel to find. The exact channel, not just a vibe 🔍

✨ DESCRIPTION ✨

This function acquires the ptp_clock::pincfg_mux mutex before invoking ptp_find_pin 🔐

But listen: instead of using this function, drivers should most likely call ptp_find_pin directly from their ptp_clock_info::enable method. Like, that’s the recommended move, no cap 😌

🔥 RETURN 🔥

Pin index in the range of zero to ptp_clock_caps.n_pins - 1, or -1 if the auxiliary function cannot be found 🫶
