STRUCT ZYNQ_PLL(9)

💅 struct zynq_pll(9) — the Kernel API Manual, but make it cute

okay so bestie, welcome to the Kernel API Manual entry for struct zynq_pll and honestly? she's a whole vibe. this is the Zynq PLL clock struct and we're gonna go through her field by field, no skips, no cap 🫶

---

✨ NAME ✨

struct zynq_pll — pll clock 💖

like, literally the PLL clock. that's her job. that's the whole thing.

---

🌸 SYNOPSIS 🌸

struct zynq_pll {
    struct clk_hw   hw;
    void __iomem    *pll_ctrl;
    void __iomem    *pll_status;
    spinlock_t *lock;
    u8 lockbit;
 };

look at her. five little members. iconic behavior. ✨

🎀 Members 🎀

• hw — the handle between common and hardware-specific interfaces. she's the bridge, the connector, the main character who talks to both sides 🔥
• pll_ctrl — PLL control register. this is where the control lives, fr fr.
• pll_status — PLL status register. the status goes here. very much "how are we doing" energy 💅
• lock — register lock. it locks the register. the way that it just... does that 😭
• lockbit — indicates the associated PLL_LOCKED bit in the PLL status register. so like, it points at the specific locky bit in pll_status, iykyk 🔒

🦋 SEE ALSO 🦋

go check out the kernel file ./drivers/clk/zynq/pll.c — it's giving source of truth:

• zynq_pll_determine_rate(9)
• zynq_pll_recalc_rate(9)
• zynq_pll_is_enabled(9)
• zynq_pll_enable(9)
• zynq_pll_disable(9)
• clk_register_zynq_pll(9)

literally a whole friend group of functions, obsessed 🌈

ok that's the whole page bestie, every single member accounted for, nothing skipped, we ate and left no crumbs 👑

this lil number lives in ./drivers/clk/zynq and the version/date sitch is October 2026 — mwah, catch you on the next manpage, bye bestie! 💜🧚
