STRUCT EMC1812_DATA(9)

💜 NAME 💜

struct emc1812_data — bestie, it's literally just the info about chip parameters ✨

okay so before we dive in: this page is from the Kernel API Manual, section 9, and it's all about one little struct named struct emc1812_data. she's not complicated, she's just thorough 🎀

🌸 SYNOPSIS 🌸

struct emc1812_data {
    const char *labels[EMC1812_MAX_NUM_CHANNELS];
    unsigned long active_ch_mask;
    const struct emc1812_features *chip;
    struct regmap *regmap;
    bool recd34_en;
    bool recd12_en;
    bool apdd_en;
 };

look at her 🥹 seven members, zero drama, all vibes.

🦋 Members 🦋

• labels — the labels of the channels, iykyk 💅 literally an array of const char * sized EMC1812_MAX_NUM_CHANNELS
• active_ch_mask — which channels are active, as an unsigned long bitmask 👑
• chip — a pointer to the structure that holds the chip features, a const struct emc1812_features * 🧚
• regmap — the device register map, struct regmap * ⭐
• recd34_en — the state of Resistance Error Correction (REC) on channels 3 and 4 🔥 (yes, REC, spelled out, no cap)
• recd12_en — the state of Resistance Error Correction (REC) on channels 1 and 2 🌈
• apdd_en — the state of anti-parallel diode mode 🦋

ngl, the two REC booleans being split by channel pair is the kind of detail that eats, and you should keep them straight: 34 = channels 3 and 4, 12 = channels 1 and 2. don't mix them up bestie 😭

⭐ SEE ALSO ⭐

• Kernel file ./drivers/hwmon/emc1812.c — the main character herself 💖
• struct emc1812_features(9) — her supporting cast 🫶

aaaand that's the whole page, no filler, no skips 💅

sign-off time: this page lives in the ./drivers/hwmon directory, dated October 2026, and it's filed under struct emc1812_data(9). go forth and read the kernel source, bestie, you've got this 🎀✨
