si570_set_frequency(9)

💅 si570_set_frequency(9) — like, the Kernel API Manual page, bestie ✨

okay so welcome to the Kernel API Manual entry for si570_set_frequency(9), and yes we are gonna read it together bc this one's short and lowkey iconic 🎀

🌸 NAME 🌸

si570_set_frequency — adjust output frequency ✨

that's it. that's the whole vibe. it adjusts the output frequency 🦋

---

🩷 SYNOPSIS 🩷

int si570_set_frequency (struct clk_si570 *data , unsigned long
frequency );

that's the whole call, bestie — takes your data pointer, takes a frequency, hands you back an int 🫶

---

💖 ARGUMENTS 💖

• data — the driver data structure. yes, THE data. your whole situation. 🗂️
• frequency — the target frequency. Returns 0 on success. 👑 (yes, that "returns 0 on success" is glued onto the frequency argument in the original and we are honoring it exactly, no notes 💀)

---

🔥 DESCRIPTION 🔥

so like. lowkey the whole job of this function is to update the output frequency — but heads up, it's only for the big glow-ups 🦋

we're talking big frequency changes, and by big we mean > 3,500 ppm — that's the threshold, that's the line in the sand, that's the vibe check 💅

so if your change is bigger than 3,500 ppm, this is your girl. if it's smaller… girl, go look at si570_set_frequency_small(9) 🙈 (it's literally in SEE ALSO, the manpage knew)

🧚 SEE ALSO 🧚

the kernel file in question is ./drivers/clk/clk-si570.c — go read it, iykyk 🍓

✨🧚‍♀️ sign-off time 🧚‍♀️✨

so this lil page lives under ./drivers/clk, it's from October 2026, it's the si570_set_frequency(9) entry in the Kernel API Manual, and honestly? she ate. no cap. go set some big frequencies, bestie 💜🎀
