STRUCT TI_TEMP_SENSOR(9)

💅 struct ti_temp_sensor(9) 💅

okay so this is from the Kernel API Manual, and it's literally the whole vibe of struct ti_temp_sensor — aka bandgap temperature sensor configuration data. no cap, that's the NAME section, we're moving. ✨

🎀 SYNOPSIS 🎀

bestie, here's the whole struct, exact and untouched, look at her:

struct ti_temp_sensor {
    struct temp_sensor_data         *ts_data;
    struct temp_sensor_registers    *registers;
    char *domain;
    const int                       slope_pcb;
    const int                       constant_pcb;
    int (*register_cooling)(struct ti_bandgap *bgp, int id);
    int (*unregister_cooling)(struct ti_bandgap *bgp, int id);
 };

✨ Members ✨

okay so let's go field by field, no skipping, we respect all of them 🫶

• ts_data — a pointer to the struct that holds the thresholds and the limits of the temperature sensor. she's got boundaries, we love that for her.
• registers — pointer to the list of register offsets and bitfields. like the address book for where everything actually lives.
• domain — the name of the domain where the sensor is located 💖 iykyk.
• slope_pcb — sensor gradient slope info for the hotspot extrapolation equation, with no external influence. yes that's the exact phrasing, it's giving very specific and we're keeping it.
• constant_pcb — sensor gradient const info for the hotspot extrapolation equation, with no external influence. twin of the one above, different job 💅
• register_cooling — a function that describes how this sensor is going to be cooled. signature is int (*register_cooling)(struct ti_bandgap *bgp, int id); — she takes the bgp and an id, periodt.
• unregister_cooling — a function to release cooling data. signature is int (*unregister_cooling)(struct ti_bandgap *bgp, int id); — the cleanup bestie, main character energy honestly.

🌸 Description 🌸

so this is a data structure that describes a temperature sensor handled by a bandgap device. iconic honestly 🔥

the whole point is that she provides configuration details on this sensor — literally:

• how to access the registers affecting this sensor
• the shadow register buffer
• how to assess the gradient from hotspot
• how to cooldown the domain when the sensor reports too hot temperature 😭

that's it, that's the job, and she does it beautifully 🌈
