💖 rt5514_calc_dmic_clk(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes we're doing kernel docs today and honestly? iconic. this one's about our girl rt5514_calc_dmic_clk, and she's a tiny little helper function who just wants to pick a divider for you. that's it. that's her whole job. slay. 💅

🌸 NAME 🌸

rt5514_calc_dmic_clk — Calculate the frequency divider parameter of dmic.

like, literally that. she calculates the divider parameter. for the dmic. no cap. ✨

---

🎀 SYNOPSIS 🎀

int rt5514_calc_dmic_clk (struct snd_soc_component *component , int rate );

she takes two things and hands you back an int. that's the whole vibe check. 🫶

---

🦋 ARGUMENTS 🦋

• component — okay so lowkey? this one is only used for dev_warn. that's it. she's not doing anything glamorous with it, she's just there so we can yell into the log if something goes sideways. main character energy, minimal responsibilities. 😭
• rate — the base clock rate. that's the number she's gonna crunch. feed her your rate and she'll do her little math. 🍓

---

✨ DESCRIPTION ✨

So here's the tea ☕ — she chooses the divider parameter that gives the highest possible DMIC frequency within the 1MHz - 3MHz range. That's the entire mission statement. Highest possible, but stay in the range. Balanced. Curated. Aesthetic. 💜
