STRUCT GPMI_NFC_HARDWARE_TIMING(9)

🎀 struct gpmi_nfc_hardware_timing(9) 🎀

okay bestie, welcome to the Kernel API Manual — this one's a struct page, it's giving "backstage pass to the NAND controller" energy, and honestly? kinda iconic. let's get into it 💅

✨ NAME ✨

struct gpmi_nfc_hardware_timing — the GPMI hardware timing parameters, periodt. this is literally the little bundle of numbers that tells your hardware how to vibe-check its own clock 🌸

---

🦋 SYNOPSIS 🦋

struct gpmi_nfc_hardware_timing {
    bool must_apply_timings;
    unsigned long int clk_rate;
    u32 timing0;
    u32 timing1;
    u32 ctrl1n;
};

look at her. five fields. main character energy fr fr 🔥

👑 Members 👑

• must_apply_timings — whether the controller timings have already been applied or not. lowkey a little flag that keeps track of itself. and ngl, it's useful only while there is support for only one chip select — so like, one-chip-select era only, iykyk 🙈
• clk_rate — the clock rate that must be used to derive the following parameters. so basically the mother of the next few values, everything downstream gets calculated from her 💖
• timing0 — the HW_GPMI_TIMING0 register. that's it, that's the whole vibe ✨
• timing1 — the HW_GPMI_TIMING1 register. yes bestie, there's a second one, and yes it's numbered correctly 🎀
• ctrl1n — the HW_GPMI_CTRL1n register. note the little n, she's fancy 🌈

🌸 SEE ALSO 🌸

• the kernel file ./drivers/mtd/nand/raw/gpmi-nand/gpmi-nand.h — go read the source, it's where she lives 🫶

💀 reminder bestie: this is a struct definition page, so there's no options, no exit statuses, no signals — just fields. don't go looking for extra lore, it's genuinely not here 🙈
