STRUCT EC_PARAMS_CHARGER_CONTROL(9)

💅 struct ec_params_charger_control(9) — Charger control parameters ✨

okay so welcome to the Kernel API Manual, bestie 🫶 this one's a little struct that tells your Chromebook EC how to do charger things — how much current, what OTG voltage, and whether the base is allowed to charge. tiny struct, big main character energy 👑

---

🌸 NAME 🌸

struct ec_params_charger_control — charger control parameters, literally the vibes you send to the EC to control charging 🔌

---

✨ SYNOPSIS ✨

struct ec_params_charger_control {
    int16_t max_current;
    uint16_t otg_voltage;
    uint8_t allow_charging;
 };

ngl the indentation on that closing brace is exactly how the original has it, so we're keeping it, no notes 💀

🎀 Members 🎀

• max_current — the charger current, in mA. positive means "go off, let the base draw up to max_current and (possibly) charge the battery" 🔋 negative means you're flipping it and requesting current from the base — that's OTG mode, iykyk.
• otg_voltage — the voltage in mV to use when you're in OTG mode. but bestie, it's fully ignored if max_current is >= 0 — it only matters when you're pulling current the other way 🙈
• allow_charging — whether the base battery is allowed to charge. and like, it only makes sense if max_current > 0, otherwise it's just a number doing nothing 🧚

that's the whole page, you ate that 💅✨

this lil baddie lives over in ./include/linux/platform_data, and it was serving October 2026 energy when this page got written — mwah, see u next time bestie 🎀💖
