STRUCT I3C_CCC_SETDA(9)

💅 struct i3c_ccc_setda — like, the whole vibe ✨

Okay so bestie, we're deep in the Kernel API Manual today and this one's a tiny lil struct with main character energy. It's struct i3c_ccc_setda(9) and honestly? She's small but she's important. 🎀

---

🌸 NAME 🌸

struct i3c_ccc_setda — the payload that gets passed to the SETNEWDA and SETDASA CCCs. That's it, that's the whole job, and she does it flawlessly. 🫶

---

✨ SYNOPSIS ✨

struct i3c_ccc_setda {
    u8 addr;
 };

Look at her. One field. Zero drama. Iconic. 👑

---

🦋 MEMBERS 🦋

• addr — the dynamic address you're assigning to an I3C device. This is the actual number that's gonna become that device's whole identity, no pressure or anything 😭

---

💖 DESCRIPTION 💖

So here's the tea ☕ — this struct is the info that gets handed over to the SETNEWDA and SETDASA CCCs, and its entire purpose in life is to assign or change the dynamic address of an I3C device.

That's literally it. Information goes in, address gets assigned or changed, everybody slays. It's giving "tiny struct, huge responsibility." 🔥
