pwm_put(9)

💅 pwm_put(9) — like, the Kernel API Manual page, bestie

okay so real talk, this is a page from the Kernel API Manual, and it is short but it is important. we're talking about letting go of a PWM device — the graceful exit, the "thanks for everything, you can go now" moment. no cap, everybody who grabs a PWM has to give it back, and pwm_put is literally the function that does it. ✨

🎀 NAME 🎀

pwm_put — release a PWM device

like... you're done with it. you're releasing it. that's the whole vibe check. 🦋

---

✨ SYNOPSIS ✨

void pwm_put (struct pwm_device *pwm );

that's it. that's the whole signature. she's simple, she's clean, she's iconic. 👑

🌸 ARGUMENTS 🌸

• pwm — a PWM device. that's the one you're releasing, bestie. hand it over, let it go, main character energy only. 💖

okay this is the part where the page just name-drops the entire friend group, and honestly? obsessed. 💅 first off, the kernel file itself:

• Kernel file ./drivers/pwm/core.c

and then the whole squad — every single one, no skipping, fr fr:

• pwm_round_waveform_might_sleep(9)
• pwm_get_waveform_might_sleep(9)
• pwm_set_waveform_might_sleep(9)
• pwm_apply_might_sleep(9)
• pwm_apply_atomic(9)
• pwm_get_state_hw(9)
• pwm_adjust_config(9)
• pwm_capture(9)
• pwm_request_from_chip(9)

💀 reminder: pwm_put is literally the release call. you got a PWM device from somewhere in that list above? you give it back with pwm_put. that's the circle of life, iykyk.

and that's the page!! 🍓 super short, super sweet, super kernel. this masterpiece of documentation lives down in ./drivers/pwm, dated October 2026, and yes the page name at the bottom is still pwm_put(9) because consistency is also iconic. mwah 💜🧚‍♀️🌈
