STRUCT PINCTRL_MAPS(9)

💖 struct pinctrl_maps(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes we're doing kernel internals today and yes you're gonna slay it. this page is literally all about struct pinctrl_maps, which is, and i quote the universe here, a list item containing part of the mapping table. that's the whole vibe. it's one lil node in a bigger list, holding a chunk of the mapping table like it's carrying snacks for the group chat 🍓

✨ NAME ✨

struct pinctrl_maps — a list item containing part of the mapping table. that's it, that's the girl. one list item, part of the mapping table, iconic behavior only 👑

---

🦋 SYNOPSIS 🦋

struct pinctrl_maps {
    struct list_head node;
    const struct pinctrl_map *maps;
    unsigned int num_maps;
 };

no cap, that's the whole struct. three fields, all business. look at her. so compact. so mysterious. she ate 💅

🎀 Members 🎀

• node — the mapping table list node. it's the little handle that links this entry into the bigger list, like the string on a friendship bracelet 🫶
• maps — array of mapping table entries. this is the actual payload, the array where all the mapping table entries live ✨
• num_maps — the number of entries in maps. literally how many things are in that array. count 'em, bestie 🔢

and that's the page!! 💜 this lil gem lives under ./drivers/pinctrl, dated October 2026, and it's page struct pinctrl_maps(9) of the Kernel API Manual — so go forth, map your pins, and remember: every mapping table is just a bunch of list items holding hands 😭🎀
