STRUCT MBG_TM_CHIP(9)

🦋 NAME

struct mbg_tm_chip — MBG thermal monitor device data. that's it, that's the whole vibe: it's the little struct holding all the tea about one MBG thermal monitor device 💅

okay real talk, we're in the Kernel API Manual bestie, so this is kernel-struct lore, not user-facing stuff. but it's lowkey iconic so let's go 🫶

✨ SYNOPSIS

struct mbg_tm_chip {
    struct regmap                   *map;
    struct device                   *dev;
    struct thermal_zone_device      *tz_dev;
    struct mutex                    lock;
    unsigned int                    base;
    int irq;
    int last_temp;
    bool last_thres_crossed;
    struct iio_channel              *adc;
 };

no cap, that's the whole layout. now let's meet the members one by one, they each have main character energy 👑

🎀 Members

• map — the regmap for accessing MBG thermal registers. literally the doorway to all the register gossip ✨
• dev — the mbg_tm_chip device. hi bestie, it's the device itself 🌸
• tz_dev — the thermal zone device registered with the thermal framework. it's official, it's in the framework, it's got a badge 🎫
• lock — the mbg_tm_chip lock for set trip temperature. keeping things from stepping on each other, very responsible of it 🔒
• base — base register offset for this MBG instance. your starting coordinates, iykyk 📍
• irq — interrupt line used to signal threshold events. when something crosses a line, this is the one screaming about it 😭
• last_temp — last measured temperature. the most recent reading, no guessing 🔥
• last_thres_crossed — indicates whether the last interrupt crossed a threshold. a yes/no vibe check on the last interrupt 🧚
• adc — IIO ADC channel used for temperature sensing. this is where the temperature actually comes from, periodt 💜
