STRUCT PM8XXX_CHAN_INFO(9)

✨ struct pm8xxx_chan_info(9) ✨

Hey bestie, welcome to the Kernel API Manual 💖 this one's about struct pm8xxx_chan_info, which is literally the ADC channel information glow-up you didn't know you needed. Sit down, grab a strawberry 🍓, let's get into it.

🌸 NAME 🌸

struct pm8xxx_chan_info — ADC channel information 💅 that's it, that's the whole vibe.

---

🦋 SYNOPSIS 🦋

struct pm8xxx_chan_info {
    const char *label;
    const struct xoadc_channel *hwchan;
    enum vadc_calibration calibration;
    u8 decimation:2;
    u8 amux_ip_rsv:3;
 };

okay so it's giving five fields, one struct, zero drama ✨ copy it exactly, no cap, don't be out here renaming stuff 🙈

🎀 Members 🎀

Here's the breakdown of every single member, because we do not skip details in this house 👑

• label — the label of this channel, straight from the device tree 🌳 and if you didn't specify one? it defaults to the datasheet name, bestie, it's got you covered 🫶
• hwchan — a pointer to the hardware channel information, aka the muxing & scaling settings 🔥 this is where the actual hardware tea lives
• calibration — tells you whether to use absolute or ratiometric calibration ⭐ pick your fighter
• decimation — the valid values are 0, 1, 2, 3 🎚️ literally just those four, iconic
• amux_ip_rsv — the ratiometric scale value, but only if you're using ratiometric calibration 💀 the values are 0, 1, 2, 4, 5 (yes, 3 is missing, don't come for me, that's just what it says 🙈)
