eswin_calc_pll(9)

💖 NAME 💖

eswin_calc_pll(9) — okay bestie, this is the Kernel API Manual page for eswin_calc_pll, and its whole iconic job is to calculate PLL values. That’s it. That’s the vibe. ✨

🦋 SYNOPSIS 🦋

void eswin_calc_pll (u32 *frac_val , u32 *fbdiv_val , unsigned long rate
, unsigned long parent_rate );

🎀 ARGUMENTS 🎀

• frac_val — the fractional divider, periodt. 💅
• fbdiv_val — the feedback divider, no cap. 🌸
• rate — the reference rate. ⭐
• parent_rate — the parent rate, and yes it’s literally right there in the name. 🫶

🔥 DESCRIPTION 🔥

So the function calculates PLL values for frac and fbdiv, and the formulas are giving math class but make it clock-core:

fbdiv = rate * 4 / parent_rate
frac = (rate * 4 % parent_rate * (2 ^ 24)) / parent_rate

That’s the whole calculation, bestie — copy it, respect it, don’t improvise. 💜
