💖 zynqmp_is_valid_clock(9) 💖

okay bestie, welcome to zynqmp_is_valid_clock(9) — that's the page name and the function name, we love a multitasker ✨ this one lives in the Kernel API Manual and it's literally here to answer one question: is this clock valid or not?? 🕵️‍♀️

---

✨ NAME ✨

zynqmp_is_valid_clock — check whether clock is valid or not 💅

---

🎀 SYNOPSIS 🎀

int zynqmp_is_valid_clock (u32 clk_id );

that's it. that's the whole vibe check. one argument, one int coming back at you 🫶

---

🌸 ARGUMENTS 🌸

• clk_id — the clock index, aka the little number that tells you which clock we're interrogating 🔍

---

⭐ RETURN ⭐

so here's the tea, and it's giving three-possible-outcomes energy:

• returns 1 if the clock is valid ✅
• returns 0 if the clock is invalid ❌
• otherwise you get an error code 😭 (yes, "else" — that's the original wording and we're not about to improvise, fr fr)
