✨ struct zl3073x_dpll(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for struct zl3073x_dpll — the ZL3073x DPLL sub-device structure 💅 this is a genuinely iconic little struct and we're gonna go through it field by field, no skipping, no cap 🫶

🌸 NAME 🌸

struct zl3073x_dpll — the ZL3073x DPLL sub-device structure. that's it, that's the vibe ✨

🎀 SYNOPSIS 🎀

struct zl3073x_dpll {
    struct list_head                list;
    struct zl3073x_dev              *dev;
    u8 id;
    u8 check_count;
    bool phase_monitor;
    struct dpll_device_ops          ops;
    struct dpll_device              *dpll_dev;
    dpll_tracker tracker;
    struct mutex                    lock;
    enum dpll_type                  type;
    enum dpll_lock_status           lock_status;
    struct list_head                pins;
    struct ptp_clock_info           ptp_info;
    struct ptp_clock                *ptp_clock;
 };

like, look at her. fourteen fields. main character energy fr fr 👑

🦋 Members 🦋

• list — this DPLL's list entry. it's how she links up with the rest of the squad ✨
• dev — pointer to the multi-function parent device. yes, she has a parent, we all do 💖
• id — the DPLL index. her little name tag 🎀
• check_count — the periodic check counter. ticking away, doing her thing ⭐
• phase_monitor — is phase offset monitor enabled? bool, so it's a yes/no moment bestie 🦋
• ops — the DPLL device operations for this instance. this is where the actual behavior lives 🔥
• dpll_dev — pointer to the registered DPLL device. she's official now 👑
• tracker — the tracking object for the acquired reference. hi bestie, we're keeping an eye on you 💅
• lock — the per-DPLL mutex that serializes all operations. one at a time, no cutting the line, periodt 🔒
• type — DPLL type, which is either PPS or EEC. pick your fighter 💜
• lock_status — the last saved DPLL lock status. a little snapshot of where we left off 📸
• pins — list of pins. a whole list of them 🌈
• ptp_info — the PTP clock info. the lore 📖
• ptp_clock — the registered PTP clock, or NULL. girlies, sometimes she's just NULL and that's okay 😭

ngl, the lock field is doing a lot of heavy lifting here — every operation on this DPLL goes through that mutex. respect the lock, bestie 🙈
