STRUCT CLKDM_DEP(9)

💅 struct clkdm_dep(9) — Kernel API Manual, bestie edition 🎀

okay so like, welcome to the Kernel API Manual ✨ and today's main character is struct clkdm_dep — the little guy who encodes dependencies between clockdomains. no cap, he's just out here keeping track of who wakes up and who stays sleepy 😴

---

🌸 NAME 🌸

struct clkdm_dep — encodes dependencies between clockdomains 🫶

---

✨ SYNOPSIS ✨

struct clkdm_dep {
    const char *clkdm_name;
    struct clockdomain *clkdm;
    s16 wkdep_usecount;
    s16 sleepdep_usecount;
 };

---

🎀 Members 🎀

• clkdm_name — the clockdomain's name, literally just its name 💖
• clkdm — a pointer to the struct clockdomain of clkdm_name — like, the actual domain object that that name points at 👑
• wkdep_usecount — the number of wakeup dependencies causing this clkdm to wake ☀️ (she's up, she's awake, she's booked and busy)
• sleepdep_usecount — the number of sleep deps that could prevent clkdm from idling 💤 (not her catching a nap, we simply cannot allow it)

---

🦋 DESCRIPTION 🦋

Statically defined, periodt. ✨ The clkdm gets resolved from clkdm_name at runtime, so do not pre-initialize it — like, do not touch it, do not look at it, do not come for it 🙈

XXX Should also include hardware (fixed) dependencies. yeah. she knows. she's aware. it's a whole thing 💀

later babes — this page came out of ./arch/arm/mach-omap2, dated October 2026, and it's been struct clkdm_dep(9) the whole time 🍓 mwah 💅
