STRUCT ADC_JACK_COND(9)

💖 NAME 💖

ok so bestie, struct adc_jack_cond — it's literally the condition to use an extcon state, and it denotes the last adc_jack_cond element among the array (iykyk, the paren is part of the lore).

✨ SYNOPSIS ✨

struct adc_jack_cond {
    unsigned int id;
    u32 min_adc;
    u32 max_adc;
};

🎀 Members 🎀

• id — the unique id of each external connector. one of a kind, main character energy, no duplicates bestie 💅
• min_adc — min adc value for this condition. the floor, the bare minimum, the limit
• max_adc — max adc value for this condition. the ceiling, the whole entire top 🫶

🦋 Description 🦋

ok so picture this 🌸 — if you've got { .state = 0x3, .min_adc = 100, .max_adc = 200}, that means: if the ADC value is between (inclusive, like both ends count, 100 and 200 are in the club) 100 and 200, then the cable 0 and cable 1 are attached. the math is (1<<0 | 1<<1 == 0x3) and honestly? she ate 🔥

💀 big note bestie — you do NOT need to describe a condition for "no cable attached". the way that's handled for you: when no adc_jack_cond is met, state = 0 is automatically chosen. so like, the default is already iconic, don't do extra work for it ✨
