clk_get_parent(9)

📦 version 7.3.1, in nixpkgs unstable

💅 clk_get_parent — Kernel API Manual, bestie edition 🎀

Okay so picture this: you're deep in the kernel, manual page clk_get_parent(9) open, and you just want to know who's your clock's parent. That's the whole vibe of this page. Let's go.

✨ NAME ✨

clk_get_parent — get the parent clock source for this clock 🫶

Like, the clock's literal parent. Its main character ancestor. The one it answers to. iykyk.

🌸 SYNOPSIS 🌸

struct clk * clk_get_parent (struct clk *clk );

That's it. One arg. No cap, she's a one-liner.

🦋 ARGUMENTS 🦋

  • clk — clock source 💖

(yes bestie that's the whole description, it's giving minimalist icon behavior)

🌈 DESCRIPTION 🌈

So what does it actually do? It returns a struct clk corresponding to the parent clock source. Family reunion time. 🎀

And if clk is NULL? It returns NULL. Simple as that. No drama, no crash, no undefined chaos — just NULL in, NULL out. Lowkey elegant honestly.

Quick reminder: the return is either a valid struct clk * for the parent, or NULL if clk was NULL. Those are the two outcomes the page gives us. Periodt.

👑 SEE ALSO 👑

The whole clk friend group showed up, and honestly the group chat is popping off. 💀 Also there's a Kernel file mentioned: ./include/linux/clk.h — go say hi to clk.h, it holds the receipts.

That's the whole squad, go read them all, they're literally all besties. 💜

Mwah 💋 — this page lives in ./include/linux, it's the October 2026 edition, and it's filed under clk_get_parent(9). Go get that parent clock, bestie, you ate. 🌟
