clk_get_rate(9)

✨ clk_get_rate(9) ✨

okay so this is a page from the Kernel API Manual bestie, and it's about clk_get_rate — the little function that tells you how fast your clock source is actually ticking 💅

---

🌸 NAME 🌸

clk_get_rate — obtain the current clock rate (in Hz) for a clock source. This is only valid once the clock source has been enabled. like, enabled first, then ask, no skipping steps bestie 🫶

---

✨ SYNOPSIS ✨

unsigned long clk_get_rate (struct clk *clk );

---

🎀 ARGUMENTS 🎀

• clk — clock source. that's it, that's the whole vibe. hand it your clock source and it gives you the rate back 🔥

like yes that's a lot of siblings but they're all iconic in their own way 💖
