acpi_gpio_count(9)

🎀 acpi_gpio_count(9) 🎀

okay so bestie, this is the Kernel API Manual page for acpi_gpio_count(9), and it's giving short king energy. It's literally about counting the GPIOs associated with a firmware node / function, and we're gonna get into it. No cap.

✨ NAME ✨

acpi_gpio_count — count the GPIOs associated with a firmware node / function.

💅 SYNOPSIS 💅

int acpi_gpio_count (const struct fwnode_handle *fwnode , const char
       *con_id );

Two arguments, one int return, and the vibes are immaculate. Periodt.

🌸 ARGUMENTS 🌸

• fwnode — firmware node of the GPIO consumer. That's the firmware-node side of the GPIO consumer, bestie. 🫶
• con_id — function within the GPIO consumer. The function-inside-the-consumer situation, iykyk. 💅

🔥 RETURN 🔥

The number of GPIOs associated with a firmware node / function or -ENOENT, if no GPIO has been assigned to the requested function.

So yeah: you get the number of GPIOs associated with a firmware node / function, or -ENOENT if no GPIO has been assigned to the requested function. That's the whole return vibe — fr fr. 😭
