bq257xx_get_...ger_property(9)

okay so bestie, welcome to the Kernel API Manual, section 9 — this is the page for bq257xx_get_...ger_property(9), aka bq257xx_get_charger_property. 💅

✨ NAME ✨

bq257xx_get_charger_property — get a power supply property. that's the whole vibe: it's the getter for power-supply properties.

🌸 SYNOPSIS 🌸

int bq257xx_get_charger_property (struct power_supply *psy , enum
       power_supply_property psp , union power_supply_propval *val );

🎀 ARGUMENTS 🎀

• psy — power supply device; like, the power-supply object we're asking about.
• psp — power supply property to get; the specific property we want.
• val — pointer to store the property value; where the answer goes.

🦋 DESCRIPTION 🦋

okay so this function handles requests to get power supply properties, and the list includes status, health, manufacturer, online state, and various voltage/current measurements. it reads current device state and routes chip-specific property requests to appropriate handlers. no cap, it's giving switchboard energy but for power-supply properties. 💅

🔥 RETURN 🔥

Returns 0 on success or -EINVAL if property is not supported. if you get -EINVAL, that property is literally not supported — don't shoot the messenger. 😭
