STRUCT LM3692X_LED(9)

💅 NAME 💅

struct lm3692x_led — bestie, the description is literally empty. Just a dash. The manpage said "and?" and moved on. No cap. It's giving mysterious main character energy. 🎀

So welcome to the kernel API manual, where we're about to meet the struct that runs the LM3692x LED show. Pull up a chair. 🦋

✨ SYNOPSIS ✨

Okay so here's the whole vibe, verbatim, don't touch a single character:

struct lm3692x_led {
    struct mutex lock;
    struct i2c_client *client;
    struct led_classdev led_dev;
    struct regmap *regmap;
    struct gpio_desc *enable_gpio;
    struct regulator *regulator;
    int led_enable;
    int model_id;
    u8 boost_ctrl, brightness_ctrl;
    bool enabled;
 };

Look at that. Ten fields, one absolute icon of a struct. 🔥

🌸 Members 🌸

Time for the roll call — every single member, no skipping, we don't do that here 💖

• lock — the lock for reading/writing the device. It's the bouncer at the club, keeping your reads and writes from bumping into each other. 🫶
• client — pointer to the I2C client. Yeah, the whole "talking to the chip" situation lives here. 🔌
• led_dev — the LED class device pointer. This is where the LED-ness is officially registered. Iconic. 👑
• regmap — the device's register map. Your handy little translation layer for poking registers. 🗺️
• enable_gpio — the VDDIO/EN gpio used to enable the communication interface. No enable, no talking. Simple as that. ⚡
• regulator — pointer to the LED supply regulator. Power supply representation, we love to see it. 🔋
• led_enable — the LED sync to be enabled. Yep, that's the field. That's what it do. ✨
• model_id — the current device model ID, enumerated. Which flavour of chip are we on? This knows. 🏷️
• boost_ctrl — cached configuration for the boost control register. Cached, so we're not re-reading it like a clown. 💾
• brightness_ctrl — cached configuration for the brightness/brightness control. That's right, brightness slash brightness. The manpage said it twice and honestly? Same. 💡
• enabled — cached enable state of the device. Is it on? Ask this bool. ✅

Lowkey important: boost_ctrl, brightness_ctrl, and enabled are all cached states — the struct is holding onto them so you don't have to go bothering the hardware every single time. Ngl, efficient queen behaviour. 💅

If you want the real, actual, non-group-chat version of events:

Okay bye ily! This has been struct lm3692x_led(9) from the Kernel API Manual, living in ./drivers/leds, dated October 2026 — go forth and blink those LEDs responsibly 🧚💜
