STRUCT HYPERBUS_DEVICE(9)

✨ struct hyperbus_device(9) ✨

okay so bestie, welcome to the kernel API manual 💖 this one's all about struct hyperbus_device — literally the struct that represents a HyperBus slave device. iconic. no cap.

---

🎀 NAME 🎀

struct hyperbus_device — the struct that reps your HyperBus slave device, periodt 💅

---

🌸 SYNOPSIS 🌸

here's the whole vibe, verbatim, don't touch it:

struct hyperbus_device {
    struct map_info map;
    struct device_node *np;
    struct mtd_info *mtd;
    struct hyperbus_ctlr *ctlr;
    enum hyperbus_memtype memtype;
    void *priv;
 };

---

🦋 Members 🦋

every single field, bestie, and what it's giving:

• map — the map_info struct you use for accessing MMIO HyperBus flash memory ✨
• np — a pointer to the HyperBus slave device node 🌸
• mtd — a pointer to the MTD struct 👑
• ctlr — a pointer to the HyperBus controller struct 🫶
• memtype — the type of memory device, i.e. HyperFlash or HyperRAM 💀 (yes, it's one or the other, pick your fighter)
• priv — a pointer to controller-specific per-device private data 🙈 your own little stash, iykyk
