clk_hw_regis...cy_parent_hw(9)

🎀 NAME 🎀

okay bestie so clk_hw_register_fixed_rate_with_accuracy_parent_hw — say it three times fast, i dare you — is literally the function that registers a fixed-rate clock with the clock framework. that's the whole vibe. it's from the Kernel API Manual and it's giving "i have a very specific job and i do it flawlessly." periodt 💅

---

✨ SYNOPSIS ✨

clk_hw_register_fixed_rate_with_accuracy_parent_hw (dev , name ,
parent_hw , flags , fixed_rate , fixed_accuracy );

look at that signature. immaculate. six arguments, no notes. 🌸

💖 ARGUMENTS 💖

so here's the group chat roster — every single one of these matters, don't skip a single one:

• dev — the device that is registering this clock. like, who's filing the paperwork. 🫶
• name — the name of this clock. its whole identity fr.
• parent_hw — pointer to parent clk. yes, everyone has a parent. even clocks. 😭
• flags — framework-specific flags. the little personality settings.
• fixed_rate — non-adjustable clock rate. it is what it is, no cap. 💀
• fixed_accuracy — non-adjustable clock accuracy. also unchangeable. also iconic for that. 🔥

ngl that SEE ALSO list is doing main character energy on its own, but it's all real and all worth a read if you're deep in clock-provider land. 💜

and that's the page, bestie! this one's from ./include/linux, dated October 2026 — mwah, slay, go register those fixed-rate clocks with accuracy and a parent_hw, you absolute legend. 👑🌈
