omap4_dpll_r...termine_rate(9)

💅 NAME 💅

okay bestie, introducing omap4_dpll_regm4xen_determine_rate — literally the function that determines the rate for a DPLL. that's it, that's the whole vibe. and yes, we're in the Kernel API Manual for this one, so buckle up 🎀

---

✨ SYNOPSIS ✨

int omap4_dpll_regm4xen_determine_rate (struct clk_hw *hw , struct
clk_rate_request *req );

no cap, that's the whole signature. copying it exactly because we do not play about precision here 💅

---

🫶 ARGUMENTS 🫶

• hw — pointer to the clock you're determining the rate for. the main character clock, if you will 👑
• req — the target rate request. this is the ask, the dream, the goal 🎯

---

🦋 DESCRIPTION 🦋

so what does it actually do? it figures out which DPLL mode to use to reach a desired rate. like, it's doing the little vibe check on the DPLL 😭

it checks whether the DPLL should be in bypass mode or locked mode — and if it's locked, it goes ahead and calculates the M,N values for the DPLL. the way that it just computes those M,N values on the spot?? obsessed ✨

returns 0 on success, and a negative error value otherwise. so if you see anything below zero, that's not slay, that's a fail 🙈

fr fr, that's the whole page — nothing dropped, nothing invented, just the facts with better energy 💅

and that's a wrap on this lil manpage moment 🌸 — big love from the ./drivers/clk/ti corner of the kernel, dated October 2026, and remember bestie: omap4_dpll_regm4xen_determine_rate(9) ate and left no crumbs 🎀🦋💜
