STRUCT ZYNQ_PINMUX_FUNCTION(9)

✨ struct zynq_pinmux_function(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 — section 9, kernel-land, where the pinmux magic lives. this page is all about struct zynq_pinmux_function, and yes it's giving very much "small struct, big responsibilities" energy 🎀

---

🌸 NAME 🌸

struct zynq_pinmux_function — literally just a pinmux function. that's the whole vibe. a struct that describes one pinmux function, no cap 💅

---

🦋 SYNOPSIS 🦋

here's the struct in all its glory, copied exactly, don't @ me:

struct zynq_pinmux_function {
    const char *name;
    const char * const *groups;
    unsigned int ngroups;
    unsigned int mux_val;
    u32 mux;
    u32 mux_mask;
    u8 mux_shift;
 };

---

👑 Members 👑

okay so every single field, one by one, no skipping, we're thorough like that 🫶

• name — the name of the pinmux function. that's it. that's the field. iconic honestly ⭐
• groups — the list of pingroups for this function. think of it as the function's friend group 🌈
• ngroups — how many entries are chillin' in groups. the headcount, if you will 💀
• mux_val — the selector for this function 🎯
• mux — offset of the function specific mux 📍
• mux_mask — mask for the function specific selector 🎭
• mux_shift — shift for the function specific selector 🌀

ngl bestie, mux_val, mux, mux_mask and mux_shift are all function specific — that's the manual's words, not mine, so don't come for me 🙈
