_enable_clocks(9)

💅 _enable_clocks(9) — Kernel API Manual, but make it make sense 🎀

okay so bestie, welcome to the Kernel API Manual entry for _enable_clocks — it's giving "tiny function, huge friend group" energy, and I'm obsessed. Let's get into it. ✨

---

🌸 NAME 🌸

_enable_clocks — enable hwmod main clock and interface clocks. literally what it says on the tin, no cap. 💖

---

🦋 SYNOPSIS 🦋

int _enable_clocks (struct omap_hwmod *oh );

that's it. that's the whole vibe check. one function, one argument, main character energy. 👑

---

🎀 ARGUMENTS 🎀

• oh — type struct omap_hwmod *. this is the hwmod you're handing over, like "here bestie, take this, do your thing." 🫶

---

⭐ DESCRIPTION ⭐

So here's the tea: _enable_clocks enables all the clocks necessary for register reads and writes to succeed on the hwmod oh. all of them. the main clock, the interface clocks, the whole squad — because if the clocks aren't on, your register reads and writes are just... not happening. 💀

And then? It returns 0. that's the flex. clean, simple, iconic. ✅

ngl, if you're poking around hwmod clock-adjacent internals, you're already kind of a legend. read the source file, it's right there. 💅
