STRUCT TSADC_TABLE(9)

💖 struct tsadc_table(9) 💖

okay so bestie, you know how a temperature sensor just spits out raw ADC numbers and absolutely refuses to tell you how hot anything actually is? yeah. this struct is the glow-up translator for that. it's the code to temperature conversion table and it's lowkey the main character of rockchip_thermal.c iykyk 🌡️✨

(the manual name is struct tsadc_table(9), from the Kernel API Manual, in case you were wondering 🫶)

---

✨ SYNOPSIS ✨

here's the whole vibe, no cap:

struct tsadc_table {
    u32 code;
    int temp;
};

that's it. two fields. iconic minimalism 💅

🎀 Members 🎀

• code — the value of the adc channel. like, the raw number the sensor hands you 🌸
• temp — the temperature. the actual temperature bestie, the thing you actually wanted 🔥

---

🦋 Note 🦋

okay so here's the important bit, listen up 👑

the code to temperature mapping of the temperature sensor is a piece wise linear curve. that means any temperature, or any code, that's faling between two given temperatures/codes can be linearly interpolated — you just draw a straight lil line between the two known points and vibe check where your value lands 📈✨

⚠️ and this part is fr fr important: the code to temperature mapping should be updated based on manufacturer results. don't just make numbers up, bestie 😭 the manufacturer hands you the real table, you put it in. that's the whole deal.
