💅 dpll_pin_ref_sync_pair_add(9) — the kernel API manual, but make it make sense

okay so bestie, this is a page from the Kernel API Manual (section 9, kernel land, we love her) and it's all about dpll_pin_ref_sync_pair_add ✨ — the function that literally creates a reference sync signal pin pair. That's the whole vibe. Let's get into it 🫶

---

✨ NAME ✨

dpll_pin_ref_sync_pair_add — create a reference sync signal pin pair 💖

---

🌸 SYNOPSIS 🌸

int dpll_pin_ref_sync_pair_add (struct dpll_pin *pin , struct dpll_pin
       *ref_sync_pin );

---

🎀 ARGUMENTS 🎀

• pin — the pin which produces the base frequency. she's the main character of frequencies fr fr 💅
• ref_sync_pin — the pin which produces the sync signal. the supporting icon that keeps everything in sync ✨

---

🦋 DESCRIPTION 🦋

so here's the tea: once pins are paired, the user-space configuration of reference sync pair is possible. that's it, that's the whole plot 👑

literally — pair them up and user space can configure the reference sync pair. no cap 💜

---

🔥 CONTEXT 🔥

acquires a lock (dpll_lock). yes bestie, she locks. respect the lock 🙈

---

⭐ RETURN ⭐

• 0 on success 🎉
• negative — error value 💀
