💅 clk_set_max_rate — the "no, babes, that's too fast" function

Okay so bestie, you're reading the Kernel API Manual and you clicked on clk_set_max_rate. This is the one that tells a clock source "you can go up to here and not a single Hz more." Iconic, honestly.

✨ NAME ✨

clk_set_max_rate — set a maximum clock rate for a clock source 🎀

🌸 SYNOPSIS 🌸

int clk_set_max_rate (struct clk *clk , unsigned long rate );

🦋 ARGUMENTS 🦋

  • clk — clock source. the main character of this whole operation 💅
  • rate — desired maximum clock rate in Hz, and it's inclusive, meaning that exact number is allowed, no cap-on-the-cap energy ✨

💖 DESCRIPTION 💖

It returns success (0) or a negative errno. That's the whole vibe report — 0 means slay, negative means something went sideways 🫶

🔥 SEE ALSO 🔥

Kernel file ./include/linux/clk.h — that's where all the clock lore lives, go read it, iykyk 📖✨

And pookie, there are so many friends in this clock friend group, buckle up:
