STRUCT NMK_FUNCTION(9)

✨ struct nmk_function(9) ✨

okay bestie, welcome to the Kernel API Manual — yes the manual name is literally Kernel API Manual and we're about to read it together like it's the group chat receipts 💅 this one's about struct nmk_function, the Nomadik pinctrl mux function. iconic little struct, no cap 🎀

---

🌸 NAME 🌸

struct nmk_function — the Nomadik pinctrl mux function. that's it, that's the whole vibe 🦋

---

✨ SYNOPSIS ✨

struct nmk_function {
    const char *name;
    const char * const *groups;
    unsigned int ngroups;
 };

three members. tiny struct. main character energy 👑

---

💖 Members 💖

• name — the name of the function, and it gets exported to the pinctrl core. she's famous, she's out there, everybody knows her name 🎤✨
• groups — an array of pin groups that may select this function. like a little roster of who's allowed to show up to this function's party 🫶
• ngroups — the number of entries in groups. the headcount, the attendance number, the "how many besties are actually coming" check 🧚
