STRUCT ZYNQMP_PMUX_FUNCTION(9)

💅 struct zynqmp_pmux_function(9) — like, the whole entire manual, bestie

okay so this is a page from the Kernel API Manual (yes, that Kernel API Manual, the big one) and it's all about one tiny lil struct that's genuinely carrying the whole pinmux situation on its back. no cap. let's get into it 🎀

---

✨ NAME ✨

struct zynqmp_pmux_function — it's a pinmux function. that's the vibe. that's the whole vibe. 💫

---

🌸 SYNOPSIS 🌸

here's the shape of it, literally copy-paste exact, don't touch a single character bestie:

struct zynqmp_pmux_function {
    char name[MAX_FUNC_NAME_LEN];
    const char * const *groups;
    unsigned int ngroups;
 };

like… look at her. three fields. immaculate. 🫶

---

🦋 Members 🦋

okay so let's go field by field, main-character by main-character:

• name — the name of the pin mux function. that's it, that's the label, she's named 💖
• groups — the list of pin groups for this function. like the group chat membership list but for pins 🔥
• ngroups — the number of entries in groups. the headcount. the "how many people are in this gc" number 💀

---

👑 Description 👑

so what does this struct actually do? it holds information about the pin control function and the function group names that support that function. that's the whole job. she holds the info, she supports the function, she slays. periodt. ✨

ok and one last thing — this page lives under ./drivers/pinctrl and it's dated October 2026, and the manual name is struct zynqmp_pmux_function(9) in case you forgot already 🙈
