STRUCT CLK_FRAC(9)

✨ struct clk_frac(9) ✨

okay so bestie, welcome to the Kernel API Manual — this one's about struct clk_frac, the mxs fractional divider clock 🎀. yes it's niche. yes it's iconic. let's get into it 💅

---

🌸 NAME 🌸

struct clk_frac — mxs fractional divider clock 🕰️✨

---

🦋 SYNOPSIS 🦋

struct clk_frac {
    struct clk_hw hw;
    void __iomem *reg;
    u8 shift;
    u8 width;
    u8 busy;
 };

like, that's the whole struct, no cap. five members, zero notes 💀

💖 Members 💖

• hw — the clk_hw for the fractional divider clock. it's literally the clock's main character energy 👑
• reg — register address 📍 that's where the vibes live
• shift — the divider bit shift 🪄 it's giving "where do the bits start"
• width — the divider bit width 📏 how many bits we're working with, periodt
• busy — busy bit shift 🚦 this is the one that says "hold up, still working" — lowkey important

---

🌈 Description 🌈

so the tea ☕: this clock is an adjustable fractional divider with a busy bit to wait when the divider is adjusted. that's it, that's the vibe — you tweak the divider, and that busy bit makes you wait until it's done. no rushing her, she's on her own timeline 😌💅
