✨ omap2xxx_clkt_dpllcore_init(9) ✨

okay so bestie, this one's from the Kernel API Manual — we're deep in OMAP2xxx clock land and honestly it's giving very niche, very iconic 🎀

---

🌸 NAME 🌸

omap2xxx_clkt_dpllcore_init — the clk init function for dpll_ck, no cap 💅

---

🦋 SYNOPSIS 🦋

void omap2xxx_clkt_dpllcore_init (struct clk_hw *hw );

---

🍓 ARGUMENTS 🍓

• hw — bestie… the original literally says -- undescribed -- 😭 so like, that's all we've got. It's a struct clk_hw * and the docs left it at that. tragic but true 🙈

---

💖 DESCRIPTION 💖

So what this does is store a local copy of clk in dpll_core_ck so other code can query the core rate without having to clk_get, which can sleep 😴 — like, imagine having to take a nap every time you wanted a number, no thank you.

It must only be called once. Not twice, not "oops I called it again", just once. periodt ✋

No return value — it's void, it gives you nothing back and that's the vibe.

⚠️ Real talk: the source has an XXX note here, and it goes like this — if the clock registration process is ever changed such that dpll_ck is no longer statically defined, this code may need to change to increment some kind of use count on dpll_ck. So keep that in mind if you go messing with registration, iykyk 🔥
