💅 ad7380_regval_to_osr 💅

okay so welcome to the Kernel API Manual bestie, today we're looking at ad7380_regval_to_osr — literally the little function that converts an OSR register value into a ratio ✨ that's the whole vibe, that's the whole job 🫶

---

✨ NAME ✨

ad7380_regval_to_osr — convert OSR register value to ratio 🎀 no cap, that's it, that's the mission

---

🌸 SYNOPSIS 🌸

int ad7380_regval_to_osr (unsigned int regval );

like… that's the whole signature, she's short and she's iconic 👑

---

🦋 ARGUMENTS 🦋

• regval — the register value you want to check 💖 this is the thing you're handing over, bestie, so she can do her little lookup

---

⭐ RETURN ⭐

she gives you back the ratio corresponding to the OSR register 🌈 that's the good path, that's the slay path

but hmm 🙈 if regval is not in bound, she returns 1 — which is oversampling disabled, so basically the "guess we're not doing that today" answer 💀 not an error, not a crash, just 1, periodt

lowkey reminder that the ratio is the return, and 1 means oversampling is disabled — don't @ me, that's just what the manpage says 💅
