swnode_gpio_count(9)

💅 NAME 💅

okay so bestie, welcome to swnode_gpio_count(9) — straight out of the Kernel API Manual — and it is literally here to count the GPIOs associated with a device / function. that’s the whole assignment, no cap 💖

✨ SYNOPSIS ✨

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

🎀 ARGUMENTS 🎀

• fwnode — firmware node of the GPIO consumer, and yes bestie, it can be NULL for system-global GPIOs 🫶
• con_id — the function within the GPIO consumer 💅

🦋 RETURN 🦋

it returns the number of GPIOs associated with a device / function, or -ENOENT if no GPIO has been assigned to the requested function. that’s the vibe check, periodt 😭
