zynqmp_pmux...ction_groups(9)

💅 NAME

Okay so bestie, this page is all about zynqmp_pmux_get_function_groups — the header up top literally reads zynqmp_pmux...ction_groups(9) (yes, truncated like that, iconic chaotic energy, from section 9, the Kernel API Manual) and what it does is: Get groups for the function ✨

---

🎀 SYNOPSIS

int zynqmp_pmux_get_function_groups (struct pinctrl_dev *pctldev ,
unsigned int selector , const char * const **groups , unsigned * const
num_groups );

That's the whole vibe. Four args, one int coming back at you 🫶

---

🌸 ARGUMENTS

• pctldev — Pincontrol device pointer. Like, the pinctrl device you're working with, obvs.
• selector — Function ID. This is the one that tells us which function we're talking about, no cap.
• groups — Group names. This is where the group names come back out at you.
• num_groups — Number of function groups. The count, the tally, the receipts 💅

---

🦋 DESCRIPTION

Get function's group count and group names. That's it, that's the whole thing — it hands you how many groups the function has and their names. Lowkey simple, highkey useful, fr fr 💖

⭐ RETURN

0

Just 0. That's the return value the page gives us, and we're not gonna invent any extra lore about it 🙈

And that's a wrap! This little beauty lives in ./drivers/pinctrl, dated October 2026, and the pages are labelled zynqmp_pmux...ction_groups(9) — same header, same footer, still truncated, still slaying. Mwah! 💋
