STRUCT ZL3073X_DPLL_PIN(9)

💅 struct zl3073x_dpll_pin 💅

okay so this is a page from the Kernel API Manual, and bestie, we're talking about struct zl3073x_dpll_pin — literally the DPLL pin struct, the whole main character of this file 🎀. Sit down, grab a strawberry drink, and let's get into it 💖

---

✨ NAME ✨

struct zl3073x_dpll_pin — DPLL pin, no cap, that's the whole vibe 🌸

---

🦋 SYNOPSIS 🦋

here's the glow-up, character for character, don't touch a thing:

struct zl3073x_dpll_pin {
    struct list_head        list;
    struct zl3073x_dpll     *dpll;
    struct dpll_pin         *dpll_pin;
    dpll_tracker tracker;
    struct fwnode_handle    *fwnode;
    char label[8];
    enum dpll_pin_direction dir;
    u8 id;
    u8 prio;
    bool esync_control;
    s32 phase_gran;
    enum dpll_pin_operstate operstate;
    s64 phase_offset;
    s64 freq_offset;
    u32 measured_freq;
 };

🎀 Members 🎀

okay so every single field, and what it's giving 🫶

• list — this DPLL pin's list entry, just doing its little linked-list thing 🔥
• dpll — which DPLL the pin is registered to, iykyk
• dpll_pin — pointer to the registered dpll_pin, iconic
• tracker — the tracking object for the acquired reference, it's literally keeping track 💅
• fwnode — firmware node handle ✨
• label — package label, that's char label[8] bestie, eight, don't forget 😭
• dir — pin direction
• id — pin id
• prio — pin priority, and it lives in the range <0, 14> — like, literally those are the bounds, no cap 🦋
• esync_control — embedded sync is controllable (a whole bool, we love to see it)
• phase_gran — phase adjustment granularity ⭐
• operstate — last saved operational state 💜
• phase_offset — last saved pin phase offset, saved for later 🍓
• freq_offset — last saved fractional frequency offset
• measured_freq — last saved measured frequency, a little u32 keeping receipts 💀

lowkey important: that ./drivers/dpll/zl3073x path and the date are the receipts for this whole page, so here they are, one last time 🧚

and that's the page, bestie — it's giving October 2026, straight out of ./drivers/dpll/zl3073x, and yes the manual name up top was struct zl3073x_dpll_pin(9) the entire time 👑💖 periodt ✨
