STRUCT PL031_VENDOR_DATA(9)

✨ struct pl031_vendor_data(9) ✨

okay so bestie, welcome to the pl031_vendor_data glow-up 💅 this is a page from the Kernel API Manual, and it's literally all about the per-vendor variations — like, every silicon version has its own little personality and this struct is where the diffs live 🫶

🌸 NAME 🌸

struct pl031_vendor_data — per-vendor variations 💖

---

🦋 SYNOPSIS 🦋

struct pl031_vendor_data {
    struct rtc_class_ops ops;
    bool clockwatch;
    bool st_weekday;
    unsigned long irqflags;
    time64_t range_min;
    timeu64_t range_max;
 };

no cap, that's the whole shape of it 👑

🎀 Members 🎀

• ops — the vendor-specific operations that get used on this particular silicon version. like, this is the main character of the struct fr fr ✨
• clockwatch — a bool that's set if this is an ST Microelectronics silicon version with a clockwatch function 🕰️
• st_weekday — a bool for when this is an ST Microelectronics silicon version that need the weekday fix. yes bestie, the weekday fix is real and this flag is how you know 🙈
• irqflags — the special IRQ flags, per variant. each one gets its own vibe check 🔥
• range_min — the minimum date/time supported by the RTC. the earliest era this thing will acknowledge ⏳
• range_max — the maximum date/time supported by the RTC. how far into the future we're allowed to go 🌈

lowkey a reminder: these are just the fields as documented here, so don't go inventing behaviour that isn't written down, bestie 😭

that's the whole page, periodt 💅 this one shipped out of ./drivers/rtc and it's dated October 2026 — mwah, drink some water and go read your kernel source 🍓🧚💜
