devm_clk_hw...r_fixed_rate(9)

💖 NAME 💖

devm_clk_hw_register_fixed_rate — okay bestie, this one registers a fixed-rate clock with the clock framework ✨ and the "devm" part means it's all managed for you, no cap 🎀

This is a page from the Kernel API Manual, and yes the header literally reads devm_clk_hw...r_fixed_rate(9) — truncated with the little dots because it's that long, iykyk 😭

---

🌸 SYNOPSIS 🌸

devm_clk_hw_register_fixed_rate(dev, name, parent_name, flags, fixed_rate);

---

🦋 ARGUMENTS 🦋

• dev — the device that's registering this clock. it's giving "who's the parent in this relationship" energy 👑
• name — the name of this clock, her whole identity fr 💅
• parent_name — the name of the clock's parent. yes she has a mother 🌈
• flags — framework-specific flags. the little toggles, the vibe settings, the✨customization✨
• fixed_rate — the non-adjustable clock rate. as in, she does not change. iconic, unbothered, locked in 🔥

💀 quick vibe check: fixed_rate is non-adjustable — that's literally the whole point of the function. don't come for her asking for a different rate, bestie.

like, that's a whole group chat of clock functions and honestly? every single one of them ate 💅✨

anyway that's the page, bestie — she's short, she's sweet, she registers a clock that does not move, and she cleans up after herself thanks to devm. periodt 🧚‍♀️

sign-off szn: this lil beauty lives in ./include/linux, dropped October 2026, and she's page devm_clk_hw...r_fixed_rate(9) of the Kernel API Manual — mwah, go build something cute with her 💜🎀
