okay so bestie, welcome to the Kernel API Manual 💅 this one's called pwm_adjust_config(9) and honestly? she's a little glow-up function and i'm obsessed 🎀

✨ SYNOPSIS ✨

int pwm_adjust_config (struct pwm_device *pwm );

---

🎀 ARGUMENTS 🎀

• pwm — the PWM device. that's the one, bestie 💖

---

🧚 DESCRIPTION 🧚

so what does she do? this function will adjust the PWM config to the PWM arguments provided by the DT or PWM lookup table. periodt 💅

and like, that's particularly useful to adapt the bootloader config to the Linux one — no cap, that's the whole vibe. bootloader says one thing, Linux says another, and pwm_adjust_config is the friend who smooths it all out 🫶✨

🌈 RETURN 🌈

• 0 on success 🎉
• or a negative error code on failure 😭

---

🔥 CONTEXT 🔥

May sleep. 😴 yeah she naps, that's just her main character energy — plan accordingly bestie, iykyk.
