zynqmp_pll_set_rate(9)

💅 zynqmp_pll_set_rate(9)

okay bestie, buckle up — this is a page from the Kernel API Manual, and it's about one very specific little function in drivers/clk/zynqmp/pll.c. yes, that ZynqMP PLL life. we're doing it. 🦋

---

✨ NAME ✨

zynqmp_pll_set_rate — literally just, set the rate of the PLL. that's the whole gig. 👑

---

🌸 SYNOPSIS 🌸

int zynqmp_pll_set_rate (struct clk_hw *hw , unsigned long rate ,
       unsigned long parent_rate );

three args in, one int out. no cap, that's it. ✨

---

🎀 ARGUMENTS 🎀

• hw — the handle between the common clock interfaces and the hardware-specific ones. like the little bridge between vibes and silicon, iykyk 🫶
• rate — the frequency of the clock you want to set. the goal. the dream. the number. 🔥
• parent_rate — the clock frequency of the parent clock. yes you have to know your ancestry, it's giving family tree but make it clocks 🌈

---

💖 DESCRIPTION 💖

so what does it actually do? it sets the PLL divider to set the desired rate. that's the whole description, bestie — it's short, it's sweet, it ate and left no crumbs. 💅

---

🦋 RETURN 🦋

on success you get back the rate that was set — like a little "yes queen, done" confirmation. and on failure? an error code. so check it, fr fr. 😭
