STRUCT SPMI_DEVICE(9)

💅 struct spmi_device(9)

okay so real talk, welcome to the Kernel API Manual bestie — today's main character is struct spmi_device, and honestly? she's iconic. this is the basic representation of an SPMI device, and no cap, she's the blueprint. 🎀

✨ NAME ✨

struct spmi_device — the basic representation of an SPMI device. that's her. that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

okay bestie, here's the actual glow-up, copy it exactly, don't touch a single character:

struct spmi_device {
    struct device           dev;
    struct spmi_controller  *ctrl;
    u8 usid;
 };

like, that's the whole struct. three members. minimal. clean. lowkey serving structure. 💅

🫶 Members 🫶

let me break down the cast of characters for you, one by one:

• dev — the driver model representation of the device. so like, this is the device's whole persona in the driver model, her main character energy in the kernel's eyes. ✨
• ctrl — a pointer to the SPMI controller that manages the bus hosting this device. yes, she has a controller. everyone needs someone managing the bus they live on, fr fr. 🚌
• usid — this device's Unique Slave IDentifier. that's Unique Slave IDentifier, capital U, capital S, capital I, capital D — it's giving acronym royalty. and yep, it's a u8. 👑

go check out these other icons in the Kernel file ./include/linux/spmi.h, they're all in the same friend group:

• struct spmi_controller(9)
• spmi_controller_put(9)
• struct spmi_driver(9)
• spmi_driver_unregister(9)

iykyk, it's a whole ecosystem. 🌈

cute little sign-off: this one lives in ./include/linux and it's dated October 2026 — and the page itself is brought to you by struct spmi_device(9), obviously. slay. 💜
