STRUCT DRV2667_DATA(9)

💅 struct drv2667_data — Kernel API Manual (yes bestie, we're in the kernel now)

okay so picture this: it's a struct in the kernel, it's called drv2667_data, and it's literally the main character of the DRV2667 driver's private data. it holds everything the driver needs to keep track of — the input device, the I2C client, the regmap, a work item, a regulator, and some vibration numbers. no cap, it's giving "glorified backpack of pointers." 🎀

✨ SYNOPSIS ✨

struct drv2667_data {
    struct input_dev *input_dev;
    struct i2c_client *client;
    struct regmap *regmap;
    struct work_struct work;
    struct regulator *regulator;
    u32 page;
    u32 magnitude;
    u32 frequency;
 };

like, that's the whole vibe right there 🫶

🌸 Members 🌸

• input_dev — pointer to the input device. the thing that actually goes "buzz buzz" at the userspace, iykyk.
• client — pointer to the I2C client. that's our little chat line to the chip itself 💬
• regmap — register map of the device. all the chip's registers, neatly tucked into one struct so we're not out here doing raw i2c pokes like some kind of gremlin.
• work — a work item used to off load the enable/disable of the vibration. i.e. we do the on/off thing from a workqueue instead of blocking wherever we happen to be ✨
• regulator — pointer to the regulator for the IC. someone's gotta keep the power situation iconic 🔋
• page — page number. u32. it's a page. of the chip's register space. slay.
• magnitude — magnitude of the vibration event. u32. how much buzz 💥
• frequency — frequency of the vibration event. u32. how fast the buzz 💫

ngl, this struct is basically a vibe check for the whole driver — every field is a pointer or a u32 and nothing is complicated. periodt.
