omap3_nonco...termine_rate(9)

👑 omap3_noncore_dpll_determine_rate(9) 👑

okay bestie, welcome to the Kernel API Manual entry for this absolute icon of a clock function 💅✨

---

🌸 NAME 🌸

omap3_noncore_dpll_determine_rate — determine rate for a DPLL. That's the whole name, and yes it's giving main-character energy 👑

---

🦋 SYNOPSIS 🦋

int omap3_noncore_dpll_determine_rate (struct clk_hw *hw , struct
clk_rate_request *req );

---

🎀 ARGUMENTS 🎀

• hw — pointer to the clock to determine rate for, aka the clock bestie we're working on 💖
• req — target rate request, the whole goal, the vibe we're aiming for ✨

---

💜 DESCRIPTION 💜

okay so what does it actually do? It determines which DPLL mode to use for reaching a desired target rate. It checks whether the DPLL shall be in bypass or locked mode, and if locked, it calculates the M,N values for the DPLL via round-rate. Then it returns a 0 on success, negative error value in failure. No cap 🫶
