STRUCT TI_LMU(9)

✨ struct ti_lmu(9) ✨

okay bestie so we're in the Kernel API Manual today and the main character is literally struct ti_lmu — that's the whole name section, no tagline, no elevator pitch, it just shows up and says nothing. iconic behavior honestly 🎀

---

🌸 NAME 🌸

struct ti_lmu — and that's it. That's the description. Empty. Not me hyping up a struct with zero marketing copy 😭 (fr fr, the original NAME section is just the name and a dash. no cap.)

---

🦋 SYNOPSIS 🦋

so here's the whole glow-up, copy it exact please:

struct ti_lmu {
    struct device *dev;
    struct regmap *regmap;
    struct gpio_desc *en_gpio;
    struct blocking_notifier_head notifier;
};

four members, no more no less, periodt 💅

👑 Members 👑

okay let's meet the cast, one by one 🫶

• dev — the parent device pointer. it's giving "who's your parent" energy, this is the pointer back to the device that owns this whole situation 💖
• regmap — used for i2c communcation on accessing registers. (yes that's spelled communcation in the original, we do not fix it, we respect the source ✨) this is the one that actually talks to the hardware when you go poking at registers 🔥
• en_gpio — GPIO for the HWEN pin, and it's Optional with a capital O. so if you're wondering "do I need this" — nope, it's optional, it's giving guest star not main cast 🌈
• notifier — a struct blocking_notifier_head that's the notifier for reporting hwmon event. so when hwmon stuff happens, this is the group chat that gets the news 📣

lowkey reminder bestie: regmap is the i2c comms layer and en_gpio is optional — don't come for me if you forget, it's literally right there in the original 😤

that's the whole page, no crumbs left behind 🍓

sign-off time: this one lives in ./include/linux/mfd and it's dated October 2026 — so yeah, future vibes only ⭐💖

mwah, go read some kernel headers bestie 🧚🦋
