STRUCT D40_DEF_LCSP(9)

💅 struct d40_def_lcsp(9) — bestie edition

okay so this is a page from the Kernel API Manual, and we're talking about struct d40_def_lcsp, which is literally just the default LCSP1 and LCSP3 settings. that's it. that's the whole vibe. two u32s in a trench coat and honestly? iconic. 🎀

✨ NAME ✨

struct d40_def_lcsp — the default LCSP1 and LCSP3 settings, no cap. that's the entire job description 💖

---

🌸 SYNOPSIS 🌸

here's the whole struct, copy it exactly please, i'm not about to get yelled at in code review:

struct d40_def_lcsp {
    u32 lcsp3;
    u32 lcsp1;
 };

look at her. two fields. clean lines. main character energy fr fr ✨

---

🦋 Members 🦋

okay so there are exactly two members and we're gonna give each one their moment:

• lcsp3 — the default configuration for dst. that's destination, bestie, she holds down the receiving end 💅
• lcsp1 — the default configuration for src. that's source, the one doing the sending, she's giving provider 🫶

and yes, they're both u32, because of course they are, this is kernel code, everything is a u32 until proven otherwise 😭
