exynos5_dmc_get_cur_freq(9)

💖 exynos5_dmc_get_cur_freq(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ this one's a little function with a big job — it tells you what frequency the DMC is actually running at rn 🫶

---

🌸 NAME 🌸

exynos5_dmc_get_cur_freq — the function that hands you back the current DMC frequency 💅

---

✨ SYNOPSIS ✨

int exynos5_dmc_get_cur_freq (struct device *dev , unsigned long *freq
);

like, it takes two things and gives you back an int — that's the whole vibe 🎀

---

🦋 ARGUMENTS 🦋

• dev — the device whose operating frequency the framework is checking 👀 yes, that device, the one you're asking about
• freq — this is where the returned frequency value lands 🎯 it's a pointer, so the function writes it back to you, iykyk

---

💜 DESCRIPTION 💜

So basically it returns the currently used frequency of the DMC 💫

but bestie listen 🙈 the real operating frequency might be lower than you'd expect — that happens when the clock source value couldn't be divided down to the requested value 😭 no cap, the hardware said "close enough" and moved on 💀
