STRUCT BM1880_PINMUX_FUNCTION(9)

💅 struct bm1880_pinmux_function (9)

okay so bestie, welcome to the Kernel API Manual ✨ — yes, the actual kernel docs, and yes, we're gonna make it cute. this one's about struct bm1880_pinmux_function, which is literally just... a pinmux function. that's it. that's the vibe. 🎀

---

🌸 NAME 🌸

struct bm1880_pinmux_function — a pinmux function 🦋

like, the whole struct. one function. iconic.

---

✨ SYNOPSIS ✨

here's the whole glow-up, copy-pasted with love:

struct bm1880_pinmux_function {
    const char *name;
    const char * const *groups;
    unsigned int ngroups;
    u32 mux_val;
    u32 mux;
    u8 mux_shift;
 };

no cap, that's the entire thing. six fields. short king energy 👑

okay let's meet the cast, one by one, no skipping 💖

• name — the name of the pinmux function. that's its whole job. it's giving "main character introduces herself" ✨
• groups — the list of pingroups for this function. like a group chat but for pins, and everyone's invited 🎀
• ngroups — how many entries are in groups. the headcount. the attendance list, fr fr 💅
• mux_val — the selector for this function. it picks this function out of the lineup 🌈
• mux — the offset of the function-specific mux. lowkey it's just telling you where to look 👀
• mux_shift — the shift for the function-specific selector. gotta slide those bits into place, periodt 💫

ngl this struct is small but it ate. every field matters. don't skip any of them or the pinmux will simply not slay 😭
