✨ omap4_dpll_lpmode_recalc(9) ✨

okay so bestie, you're in the Kernel API Manual and this page is all about omap4_dpll_lpmode_recalc 💅

---

🌸 NAME 🌸

omap4_dpll_lpmode_recalc — compute DPLL low-power setting 🫶

---

🎀 SYNOPSIS 🎀

void omap4_dpll_lpmode_recalc (struct dpll_data *dd );

like, that's the whole signature, no cap ✨

---

🦋 ARGUMENTS 🦋

• dd — pointer to the dpll data structure. literally just a pointer, she's the main character here 👑

---

💖 DESCRIPTION 💖

so basically this function figures out if low-power mode can be enabled, based upon the last multiplier and divider values that were calculated 🔥

If low-power mode can be enabled, then the bit to enable low-power mode gets stored in the last_rounded_lpmode variable. iconic behavior, honestly 🎀

and ngl, this implementation is based upon the criteria for enabling low-power mode as described in the OMAP4430/60 Public TRM section 3.6.3.3.2 "Enable Control, Status, and Low-Power Operation Mode" 📖 — yes bestie, the TRM said what it said 💅
