STRUCT PINCTRL_DT_MAP(9)

✨ struct pinctrl_dt_map(9) ✨

okay bestie, buckle up 💖 this is a page straight out of the Kernel API Manual and it's literally all about one lil struct, so let's get into it 🫶

---

🌸 NAME 🌸

struct pinctrl_dt_map — a mapping table chunk that got parsed from the device tree, no cap 💅

---

🦋 SYNOPSIS 🦋

struct pinctrl_dt_map {
    struct list_head node;
    struct pinctrl_dev *pctldev;
    struct pinctrl_map *map;
    unsigned int num_maps;
 };

like, that's the whole vibe right there ✨

🎀 Members 🎀

• node — the list node for struct pinctrl's dt_maps field. she's linked in, she belongs somewhere 🥹
• pctldev — the pin controller that allocated this struct, and will free it too. so like, it made it, it cleans it up — main character energy, honestly 👑
• map — the mapping table entries themselves. the whole point of the party 🎉
• num_maps — how many mapping table entries there are. the headcount, if you will 🔢
