STRUCT PM8XXX_RTC(9)

💖 struct pm8xxx_rtc(9) 💖

okay so bestie, this is a page straight out of the Kernel API Manual — it's the internal structure for the RTC driver, and honestly? it's giving backstage-pass energy. this is the lil' data blob that holds everything the pm8xxx RTC driver needs to know about itself. ngl, she's organized. 🎀

✨ SYNOPSIS ✨

here's the whole struct, bestie — type it exactly like this or the compiler will simply pass away:

struct pm8xxx_rtc {
    struct rtc_device *rtc;
    struct regmap *regmap;
    bool allow_set_time;
    bool use_uefi;
    int alarm_irq;
    const struct pm8xxx_rtc_regs *regs;
    struct device *dev;
    struct qcom_uefi_rtc_info rtc_info;
    struct nvmem_cell *nvmem_cell;
    u32 offset;
    bool offset_dirty;
 };

🌸 Members 🌸

okay now the fun part — meet the cast, iykyk 💅

• rtc — the RTC device itself. literally the whole point of this struct, main character energy fr. 👑
• regmap — the regmap used to access registers. it's the little messenger that goes and pokes the hardware for you. 🦋
• allow_set_time — whether the time can be set. yes/no, can we touch the clock or not. 🙈
• use_uefi — use a UEFI variable as a fallback for the offset. backup plan behavior, we love to see it. ✨
• alarm_irq — the alarm IRQ number. when the alarm goes off, this is the digits it calls. 🔥
• regs — register description. the map of where everything lives. 🎀
• dev — device structure. the whole device situation, right here. 💜
• rtc_info — the qcom UEFI rtc-info structure. yes, the qcom one specifically, don't get it twisted. 🌸
• nvmem_cell — the nvmem cell for the offset. that's where the offset chills. 🍓
• offset — offset from epoch, in seconds. a u32, so be normal about it. ⭐
• offset_dirty — the offset needs to be stored on shutdown. it's flagged, it's marked, it's gotta get written down before we dip. 😭

fr fr, every single member up there is load-bearing — miss one and the vibe check fails at compile time 💀

okay that's the whole page, bestie 🫶 sign-off time: this one comes from the kernel source at ./drivers/rtc, straight out of the Kernel API Manual, and it's dated October 2026. periodt. 💖✨🌈
