STRUCT ST_LSM6DSX_SHUB_SETTINGS(9)

✨ struct st_lsm6dsx_shub_settings — ST IMU hw i2c controller settings ✨

Okay bestie, so this is a page straight out of the Kernel API Manual, and it's literally all about struct st_lsm6dsx_shub_settings — the ST IMU hardware i2c controller settings 💅. It's giving "one struct to rule the sensor hub" energy, and we're gonna go through every single field together, no cap. 🫶

🌸 SYNOPSIS 🌸

struct st_lsm6dsx_shub_settings {
    struct st_lsm6dsx_reg page_mux;
    struct {
      bool sec_page;
      u8 addr;
      u8 mask;
    } master_en;
    struct {
      bool sec_page;
      u8 addr;
      u8 mask;
    } pullup_en;
    struct st_lsm6dsx_reg aux_sens;
    struct st_lsm6dsx_reg wr_once;
    struct st_lsm6dsx_reg emb_func;
    u8 num_ext_dev;
    struct {
      bool sec_page;
      u8 addr;
    } shub_out;
    u8 slv0_addr;
    u8 dw_slv0_addr;
    u8 batch_en;
    u8 pause;
 };

Look at her. Iconic. Not a single field out of place. 🎀

💖 Members 💖

• page_mux — the register page mux info, and yes she comes with her addr + mask besties along for the ride.
• master_en — master config register info (addr + mask). Very main character energy for the master config.
• pullup_en — the i2c controller pull-up register info (addr + mask). Pull-ups are literally the support system of i2c, we stan. ⭐
• aux_sens — aux sensor register info (addr + mask). The aux sensor said "I'm here too!" and honestly? Valid.
• wr_once — write_once register info (addr + mask). One write, one time, no repeating yourself. 😭
• emb_func — embedded function register info (addr + mask). The embedded functions are doing the most and we love that for them. 🔥
• num_ext_dev — max number of slave devices. It's the u8 that keeps the whole friend group from getting too big. 💀
• shub_out — sensor hub first output register info. Note the vibe: this one's a bool sec_page + u8 addr situation — no mask invited to this party, iykyk. 🙈
• slv0_addr — slave0 address, but make it the secondary page. Very "you'll find me in the second location" of her. 💅
• dw_slv0_addr — slave0 write register address, also in the secondary page. So yes, slv0_addr and dw_slv0_addr are lowkey siblings and they both live in the secondary page. 🦋
• batch_en — Enable/disable FIFO batching. Flip her on, flip her off, she contains multitudes. 🔥
• pause — controller pause value. Sometimes the controller just needs a little break, and honestly same. 🌸

Ok that's the whole page, you ate that, periodt. 🎀👑
