ENUM MAX77759_CHGR_CHGIN_DTLS_STATUS(9)

✨ NAME ✨

okay so bestie, welcome to the manual page for enum max77759_chgr_chgin_dtls_status(9) — it's literally the Charger Input Status enum 💅 and it lives in section 9 of the Kernel API Manual (yes, the fancy kernel one 🎀). It's giving "small enum, big responsibilities" and honestly? we're obsessed.

🌸 SYNOPSIS 🌸

enum max77759_chgr_chgin_dtls_status {
    MAX77759_CHGR_CHGIN_DTLS_VBUS_UNDERVOLTAGE ,
    MAX77759_CHGR_CHGIN_DTLS_VBUS_MARGINAL_VOLTAGE ,
    MAX77759_CHGR_CHGIN_DTLS_VBUS_OVERVOLTAGE ,
    MAX77759_CHGR_CHGIN_DTLS_VBUS_VALID

};

that's the whole squad right there 🫶 four constants, zero drama (well, unless your VBUS is in a silly mood 💀).

💖 Constants 💖

okay so these are the four possible vibes your charger input can be giving off. let's do a vibe check on each one:

• MAX77759_CHGR_CHGIN_DTLS_VBUS_UNDERVOLTAGE — Charger input voltage (Vchgin) is literally below the Under Voltage Threshold (Vuvlo). not enough juice, it's giving "flop era" 😭
• MAX77759_CHGR_CHGIN_DTLS_VBUS_MARGINAL_VOLTAGE — Vchgin > Vuvlo and Vchgin < (Battery Voltage (Vbatt) + system voltage (Vsys)). so it's... fine? mid? the "seen but not slaying" tier 🙈
• MAX77759_CHGR_CHGIN_DTLS_VBUS_OVERVOLTAGE — Vchgin > Over Voltage threshold (Vovlo). too much! too much voltage! main character energy but in a dangerous way 🔥
• MAX77759_CHGR_CHGIN_DTLS_VBUS_VALID — Vchgin > Vuvlo, Vchgin < Vovlo and Vchgin > (Vsys + Vbatt). the it-girl of the enum ✨ everything lines up, no notes, periodt 👑

ngl, MARGINAL and VALID look similar at a glance but the conditions are lowkey different — read them both twice, bestie, don't get caught 🫶

go touch some related kernel lore, there's a whole friend group:

(and yes, max77759_maxq_command(9) shows up twice in the original list — iconic of it, honestly, no cap 💀)

this page came from the ./include/linux/mfd directory, dated October 2026, and its manual name is enum max7775..._dtls_status(9) (the truncated one, that's just how it's filed, don't come for her 🎀). slay, read responsibly, and remember: check your VBUS before you check your attitude 💅✨🌸
