STRUCT REG_SEQUENCE(9)

💅 struct reg_sequence(9) — a little glow-up for your writes 💅

okay so bestie, welcome to the Kernel API Manual page for struct reg_sequence(9) ✨ this is the little struct that carries one register write out of a whole sequence of writes, and honestly? it's giving main character energy for something so smol 🎀

---

✨ NAME ✨

struct reg_sequence — literally just an individual write from a sequence of writes 🫶

---

🦋 SYNOPSIS 🦋

struct reg_sequence {
    unsigned int reg;
    unsigned int def;
    unsigned int delay_us;
 };

(yes that's the whole thing, no cap — three lil fields and she's done 💅)

---

🌸 Members 🌸

• reg — the register address. this is which register we're talking to, iykyk 📍
• def — the register value. this is the actual thing we're writing in there 💖
• delay_us — a delay to be applied after the register write, measured in microseconds. so like, post-write chill time ⏳✨

---

💜 Description 💜

so what is this for? it's register/value pairs for sequences of writes, and each one can carry an optional delay in microseconds that gets applied after each write 🎀 that's it, that's the vibe. one struct = one write + maybe a lil pause. adorable. iconic. periodt. 👑
