STRUCT MESON_REG_DESC(9)

💅 struct meson_reg_desc(9) — kernel API manual, but make it make sense

okay so bestie, we're in the Kernel API Manual today and the main character of this page is struct meson_reg_desc. it's a tiny little struct, but she's doing so much behind the scenes. let's get into it 🎀

---

✨ NAME ✨

struct meson_reg_desc — a register descriptor. that's it, that's her job title 💖

---

🌸 SYNOPSIS 🌸

here's the whole vibe, literally character for character:

struct meson_reg_desc {
    unsigned int reg;
    unsigned int bit;
 };

two fields. two. and yet 👑 (also yes, that trailing space before the closing brace is in there, iykyk, we don't touch it)

---

🦋 Members 🦋

• reg — the register offset in the regmap. this is where she lives, fr fr 📍
• bit — the bit index in that register. this is which little bit we're talking about, no cap ⭐

---

🌈 Description 🌈

so what's the point of this whole struct? the structure describes the information needed to control pull, pull-enable, direction, etc. for a single pin 💅 and that's the entire story — one pin, one descriptor, all the pull/pull-enable/direction energy in one adorable little package 🫶

ngl it's giving "small struct, big responsibilities" and i'm obsessed 😭

okay and for the cute sign-off, the source/version + date on this one lives at ./drivers/pinctrl/meson and she's dated October 2026 🧚💜 so like… future girlie pop of the pinctrl tree. slay. periodt. 💫
