STRUCT TWL4030_MADC_REQUEST(9)

💅 NAME 💅

ok so bestie, let me introduce you to struct twl4030_madc_request — it's literally the madc request packet for channel conversion ✨ like that's its whole thing, that's the vibe 🎀

🦋 SYNOPSIS 🦋

struct twl4030_madc_request {
    unsigned long channels;
    bool do_avg;
    u16 method;
    u16 type;
    bool active;
    bool result_pending;
    bool raw;
    int rbuf[TWL4030_MADC_MAX_CHANNELS];
 };

like, that's the whole struct, no cap 👑

🌸 MEMBERS 🌸

okay now we go field by field, bestie, stay with me 🫶

• channels — a 16 bit bitmap for individual channels 💖 so like, one bit per channel, iconic little bitmap moment
• do_avg — when you turn this on it samples the input channel for 4 consecutive cycles ✨ yes, four, not three, not five, four 🌈
• method — RT, SW1, SW2 — those are the options, periodt, don't ask me for more 💅
• type — the method type: polling or interrupt based 📋 pick your fighter
• active — flag if request is active 🔥 like "is this thing on" energy
• result_pending — flag from the irq handler, that result is ready 😭 the irq handler said "it's done" and this flag is the receipt
• raw — return raw value, do not convert it 🧚 like, leave it alone, it's fine as it is
• rbuf — result buffer 🍓 it's an int array sized TWL4030_MADC_MAX_CHANNELS, that's where the results live
