pwm_add_table(9)

💖 pwm_add_table(9) — the kernel API manual, bestie edition 🌸

Okay so real talk, this is pwm_add_table from the Kernel API Manual, and it's genuinely one of the most straightforward little functions ever. No cap. Let's get into it.

---

✨ NAME ✨

pwm_add_table — register PWM device consumers 🎀

Like, it takes a table of peeps who want a PWM device and makes them official. It's giving matchmaker energy, honestly.

---

🦋 SYNOPSIS 🦋

void pwm_add_table (struct pwm_lookup *table , size_t num );

That's it. That's the whole signature. void return, so it doesn't even hand you back a status code — it just does the thing and dips. 💅

---

👑 ARGUMENTS 👑

• table — array of consumers to register. Literally the guest list 📋✨
• num — number of consumers in table. i.e. how many names are actually on that guest list, so bestie doesn't read past the end 🙈

Both of these are yours to get right. num is not vibes-based — it's the count of entries in table, periodt.

And that's the tea, bestie 🫶 — this page lives in ./drivers/pwm, dated October 2026, and the manual name on the header up top was pwm_add_table(9). Mwah, bye 💋✨
