STRUCT BQ256XX_CHIP_INFO(9)

💖 NAME 💖

struct bq256xx_chip_info — bestie, the manpage literally leaves this blank, so here's the vibe: it's the per-chip info struct for the bq256xx charger driver, and every member is listed below with its whole entire personality 🫶

This page lives in the Kernel API Manual, just so you know where you are ✨

✨ SYNOPSIS ✨

okay so here's the whole struct, no cap, every field, exactly as it is:

struct bq256xx_chip_info {
    int model_id;
    const struct regmap_config *bq256xx_regmap_config;
    int (*bq256xx_get_ichg)(struct bq256xx_device *bq);
    int (*bq256xx_get_iindpm)(struct bq256xx_device *bq);
    int (*bq256xx_get_vbatreg)(struct bq256xx_device *bq);
    int (*bq256xx_get_iterm)(struct bq256xx_device *bq);
    int (*bq256xx_get_iprechg)(struct bq256xx_device *bq);
    int (*bq256xx_get_vindpm)(struct bq256xx_device *bq);
    int (*bq256xx_set_ichg)(struct bq256xx_device *bq, int ichg);
    int (*bq256xx_set_iindpm)(struct bq256xx_device *bq, int iindpm);
    int (*bq256xx_set_vbatreg)(struct bq256xx_device *bq, int vbatreg);
    int (*bq256xx_set_iterm)(struct bq256xx_device *bq, int iterm);
    int (*bq256xx_set_iprechg)(struct bq256xx_device *bq, int iprechg);
    int (*bq256xx_set_vindpm)(struct bq256xx_device *bq, int vindpm);
    int (*bq256xx_set_charge_type)(struct bq256xx_device *bq, int type);
    int (*bq256xx_set_ts_ignore)(struct bq256xx_device *bq, bool
ts_ignore);
    int bq256xx_def_ichg;
    int bq256xx_def_iindpm;
    int bq256xx_def_vbatreg;
    int bq256xx_def_iterm;
    int bq256xx_def_iprechg;
    int bq256xx_def_vindpm;
    int bq256xx_max_ichg;
    int bq256xx_max_vbatreg;
    bool has_usb_detect;
};

(yes the ts_ignore line is broken across two lines, that's just how the original prints it, don't come for me 💅)

🧩 Members 🧩

okay bestie, member-by-member, here we go — this is the whole roster 👑

• model_id — the device instance. like, which chip are we even talking about rn.
• bq256xx_regmap_config — the regmap configuration struct. the map to the registers, iykyk.
• bq256xx_get_ichg — pointer to the instance-specific get_ichg function.
• bq256xx_get_iindpm — pointer to the instance-specific get_iindpm function.
• bq256xx_get_vbatreg — pointer to the instance-specific get_vbatreg function.
• bq256xx_get_iterm — pointer to the instance-specific get_iterm function.
• bq256xx_get_iprechg — pointer to the instance-specific get_iprechg function.
• bq256xx_get_vindpm — pointer to the instance-specific get_vindpm function.
• bq256xx_set_ichg — pointer to the instance-specific set_ichg function.
• bq256xx_set_iindpm — pointer to the instance-specific set_iindpm function.
• bq256xx_set_vbatreg — pointer to the instance-specific set_vbatreg function.
• bq256xx_set_iterm — pointer to the instance-specific set_iterm function.
• bq256xx_set_iprechg — pointer to the instance-specific set_iprechg function.
• bq256xx_set_vindpm — pointer to the instance-specific set_vindpm function.
• bq256xx_set_charge_type — pointer to the instance-specific set_charge_type function.
• bq256xx_set_ts_ignore — pointer to the instance-specific set_ts_ignore function.
• bq256xx_def_ichg — default ichg value in microamps.
• bq256xx_def_iindpm — default iindpm value in microamps.
• bq256xx_def_vbatreg — default vbatreg value in microvolts.
• bq256xx_def_iterm — default iterm value in microamps.
• bq256xx_def_iprechg — default iprechg value in microamps.
• bq256xx_def_vindpm — default vindpm value in microvolts.
• bq256xx_max_ichg — maximum charge current in microamps.
• bq256xx_max_vbatreg — maximum battery regulation voltage in microvolts.
• has_usb_detect — indicates whether the device has BC1.2 detection. 👀

lowkey important: the *_def_* ones are microamps except bq256xx_def_vbatreg and bq256xx_def_vindpm, which are microvolts. don't mix 'em up bestie 😭
