disable_clock(9)

🎀 disable_clock(9) — the kernel API manual, bestie edition 🎀

okay so this is disable_clock, from the kernel API manual, and honestly it's giving "short but iconic." One job, does it well. Let's get into it 💅

---

✨ NAME ✨

disable_clock — Disable a device clock. That's it, that's the whole vibe. It turns a clock off, periodt 🫶

---

🌸 SYNOPSIS 🌸

void disable_clock (struct device *dev , const char *con_id );

no cap, that's the whole signature. void return, so nothing comes back — you just call it and trust the process ✨

---

🦋 ARGUMENTS 🦋

• dev — the device whose clock is to be disabled. like, this one right here, bestie, this device's clock, turn it off 🔥
• con_id — the connection ID of the clock. yep, the connection ID. that's the identifier you hand over so the kernel knows which clock of that device you're talking about 🎀

fr fr, that's the entire argument list — two things, both required, no defaults, no extras. she's lowkey minimalist and I respect it 💜

👑 SEE ALSO 👑

okay so the whole friend group shows up here. the source lives in the kernel file ./drivers/base/power/clock_ops.c, and here's everyone tagged in the group chat:

• pm_clk_list_lock(9)
• pm_clk_list_unlock(9)
• pm_clk_op_lock(9)
• pm_clk_op_unlock(9)
• __pm_clk_enable(9)
• pm_clk_acquire(9)
• pm_clk_add(9)
• pm_clk_add_clk(9)

• pm_clk_suspend(9)
• pm_clk_resume(9)
• pm_clk_notify(9)
• enable_clock(9)
• pm_clk_notify(9) — yes, she's listed twice, and I'm not editing the guest list, that's what the original says 💀
• pm_clk_add_notifier(9)

like I said — pm_clk_notify(9) literally appears two times in the SEE ALSO. iconic of her to double-book, and we're keeping it exactly as-is 🙈

aaaand that's the page!! short, sweet, one function, two args, one very long SEE ALSO 🍓

cute little sign-off: this one ships from ./drivers/base/power, dated October 2026 — so mark your calendars, bestie 🧚💖

slay, go disable some clocks responsibly ✨💅
