clkdm_hwmod_disable(9)

💖 clkdm_hwmod_disable(9) — Kernel API Manual 💖

✨ NAME ✨

clkdm_hwmod_disable — remove an enabled downstream hwmod from this clkdm, bestie 💅

---

💅 SYNOPSIS 💅

int clkdm_hwmod_disable (struct clockdomain *clkdm , struct omap_hwmod
       *oh );

---

🎀 ARGUMENTS 🎀

• clkdm — a struct clockdomain *, the clockdomain in question 🌸
• oh — a struct omap_hwmod * of the disabled downstream hwmod 🦋

---

🔥 DESCRIPTION 🔥

Okay so when oh is disabled, this decrements the usecount of this clockdomain clkdm. It’s intended to be called by module_disable code. No cap.

If the clockdomain usecount goes to 0, put the clockdomain to sleep (software-supervised mode) or remove the clkdm autodependencies (hardware-supervised mode). Literally the whole vibe check ✨

Returns:

• -EINVAL — if passed null pointers 😭
• -ERANGE — if the clkdm usecount underflows 💀
• 0 — upon success or if the clockdomain is in hwsup idle mode 👑
