devfreq_eve...v_by_phandle(9)

🌸 devfreq_eve...v_by_phandle(9) 🌸

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, and yes it's giving "official documentation but make it cute." Today's main character is devfreq_event_get_edev_by_phandle (the header up top shortens it to devfreq_eve...v_by_phandle(9) because apparently even man pages have a character limit 💀). It's a section 9 kernel API page, so buckle up buttercup 🎀

✨ NAME ✨

devfreq_event_get_edev_by_phandle — literally gets you the devfreq-event dev straight out of the devicetree. no cap. 🦋

---

✨ SYNOPSIS ✨

struct devfreq_event_dev * devfreq_event_get_edev_by_phandle (struct device *dev , const char *phandle_name , int index );

look at that signature, so iconic 👑

---

✨ ARGUMENTS ✨

• dev — the pointer to the given device. like, the device you're already holding hands with 🫶
• phandle_name — name of the property holding a phandle value. it's the label on the box, basically 🎀
• index — the index into the list of devfreq-event devices. bestie, this is the "which one tho" number 💅

---

✨ DESCRIPTION ✨

note (and this is important, ngl) that this function returns the pointer of the devfreq-event device. that's the whole vibe check, fr fr. 🌈
