STRUCT LM3532_DATA(9)

💖 struct lm3532_data(9) — the kernel API manual, but make it cute ✨

okay so bestie, welcome to the <pink>lm3532_data</pink> glow-up page 💅 this is a struct from the Kernel API Manual and it's genuinely the main character of the LM3532 LED driver situation. no cap.

---

🌸 NAME 🌸

struct lm3532_data — literally the struct 🫶 (the original NAME line is just the struct name, so yeah, that's the whole vibe)

---

✨ SYNOPSIS ✨

here's the shape of it, copied exactly because we do not mess with code:

struct lm3532_data {
    struct gpio_desc *enable_gpio;
    struct regulator *regulator;
    struct i2c_client *client;
    struct regmap *regmap;
    struct device *dev;
    struct mutex lock;
    struct lm3532_als_data *als_data;
    u32 runtime_ramp_up;
    u32 runtime_ramp_down;
    struct lm3532_led leds[];
 };

like, look at her. she's got pointers, she's got a mutex, she's got a flexible array at the end. iconic 💀✨

🎀 Members 🎀

okay so let's go through every single member, because we are not skipping any 🍓

• enable_gpio — the hardware enable gpio. it's a struct gpio_desc *, and it's the one doing the hardware-enable thing, iykyk.
• regulator — the regulator 💖 (yes that's the whole description, and yes it's still important).
• client — the i2c client.
• regmap — the device's register map. this is where the register magic lives 🔥
• dev — a pointer to the device's struct device. the whole "which device even am I" of it all.
• lock — the lock for reading/writing the device. take it before you touch the registers, bestie, fr fr 🔒
• als_data — a pointer to the als data struct (struct lm3532_als_data *). ambient light sensing vibes, no cap.
• runtime_ramp_up — the runtime ramp up setting.
• runtime_ramp_down — the runtime ramp down setting. she's the cooler sister of the one above, lowkey.
• leds — an array of LED strings. it's struct lm3532_led leds[], a flexible array member, and yes it's last in the struct for a reason 👑

🌈 SEE ALSO 🌈

• struct lm3532_led(9) — the other struct, go look at her too 🦋

and that's the whole page, bestie, you ate it up 💅💖

oh and the footer stuff? it came from the ./drivers/leds corner of the kernel tree, dated October 2026, and the page is, obviously, struct lm3532_data(9). slay ✨🎀🫶
