STRUCT MMA_CHIP_INFO(9)

✨ struct mma_chip_info(9) ✨

okay so bestie, this is a page straight outta the Kernel API Manual, section 9, and it's all about struct mma_chip_info — literally the glow-up cheat sheet for chip-specific data 🫶

💖 NAME 💖

struct mma_chip_info — chip specific data, no cap 💅

🌸 SYNOPSIS 🌸

struct mma_chip_info {
    const char *name;
    u8 chip_id;
    const struct iio_chan_spec *channels;
    int num_channels;
    const int mma_scales[3][2];
    int all_events;
    int enabled_events;
 };

like… she's serving struct realness, exactly as written, don't touch a single character 🔥

🎀 Members 🎀

• name — the part number of the device, and it gets reported via the 'name' attr. icon behavior tbh ⭐
• chip_id — the value sitting in the WHO_AM_I register. yes that's the real register name and yes it's iconic 👑
• channels — a struct iio_chan_spec that matches whatever the device's capabilities are. vibes matched to hardware fr fr 💫
• num_channels — number of channels. that's it, that's the whole job 🍓
• mma_scales — scale factors for converting register values to m/s^2. she's got 3 modes: 2g, 4g, 8g, and 2 integers per mode: m/s^2 and micro m/s^2. main character energy, three outfits, two numbers each 💅✨
• all_events — all events supported by this chip. every single one, we love a completist 💖
• enabled_events — the event flags that are enabled and handled by this driver. the chosen ones 🙈

ngl, if you're writing a driver against this, keep every field exactly as listed — the kernel does not do "close enough" 😭

🦋 SEE ALSO 🦋

• Kernel file ./drivers/iio/accel/mma8452.c — go read it, it's giving source of truth 🌈

and that's the page bestie, you ate 💖 this lil gem lives in ./drivers/iio/accel, dated October 2026, filed under struct mma_chip_info(9) — slay, periodt 🎀✨
