STRUCT ABX500_FUNCTION(9)

💅 struct abx500_function(9) — like, the whole vibe

okay so bestie, welcome to the Kernel API Manual ✨ we're looking at struct abx500_function(9) today and honestly? she's a little legend 🎀

Weird manpage name formatting aside (the header literally says struct abx500_function(9) on both sides, iconic of it), let's get into it. This is the ABx500 pinctrl mux function — the struct that tells the pinctrl core "hey, here's a function, here's the pin groups that can select it" 🦋

✨ SYNOPSIS ✨

struct abx500_function {
    const char *name;
    const char * const *groups;
    unsigned ngroups;
 };

That's literally it. Three members. Small but mighty, no cap 🔥

🌸 Members 🌸

• name — the name of the function, and yes she gets exported to pinctrl core 💅 that's her whole moment.
• groups — an array of pin groups that may select this function. like, the whole friend group that could show up for her 🫶
• ngroups — the number of entries in groups. gotta know how many besties are coming so nobody's left standing outside 😭

👑 SEE ALSO 👑

• The kernel file ./drivers/pinctrl/nomadik/pinctrl-abx500.h 🍓

• struct abx500_pinrange(9)
• struct abx500_pinctrl_soc_data(9)

all the cousins fr fr — go say hi, they're all in the same header 💖

ngl the whole reason she exists is so the pinctrl core knows what's what, and we respect that 💀

so yeah, that's the page!! sourced from ./drivers/pinctrl/nomadik, dated October 2026, and it's struct abx500_function(9) forever and always 🌈 mwah, go read the other structs bestie 💜
