STRUCT HMC5843_DATA(9)

struct hmc5843_data(9) 🦋

okay so bestie, this page is from the Kernel API Manual, and it's giving “device-specific data, but make it a struct.” no cap, it's literally the blueprint for struct hmc5843_data. 💅

✨ NAME ✨

struct hmc5843_data — device specific data 🎀

🎀 SYNOPSIS 🎀

       struct hmc5843_data {
           struct device *dev;
           struct mutex lock;
           struct regmap *regmap;
           const struct hmc5843_chip_info *variant;
           struct iio_mount_matrix orientation;
           struct {
             __be16 chans[3];
             aligned_s64 timestamp;
           } scan;
        };

🫶 Members 🫶

• dev — actual device, the main character of this lil' struct 💖
• lock — update and read regmap data 🔒
• regmap — hardware access register maps 🗺️
• variant — describe chip variants 🌈
• scan — buffer to pack data for passing to iio_push_to_buffers_with_ts 📦

also yes, orientation is right there in the struct as a struct iio_mount_matrix; the original member rundown just doesn't give it a separate blurb. iykyk 🦋
