pch_vbus_gpio_init(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… pch_vbus_gpio_init πŸ’…

Okay bestie, so this one's from the Kernel API Manual β€” it's pch_vbus_gpio_init, and it lives out there in the land of kernel docs. Let me tell you what it does because honestly it's giving "small function, big job" energy ✨


πŸŽ€ NAME πŸŽ€

pch_vbus_gpio_init β€” this API initializes a GPIO port that detects VBUS. That's it, that's the whole vibe. It's the little setup step that gets your VBUS-sensing GPIO ready to, y'know, sense. πŸ¦‹


✨ SYNOPSIS ✨

int pch_vbus_gpio_init(struct pch_udc_dev *dev);

🌸 ARGUMENTS 🌸

  • dev β€” a reference to the driver structure. Yes, that driver structure. Hand it over and let the function do its thing 🫢

πŸ’– DESCRIPTION πŸ’–

So real talk, here's the return-code tea β˜• β€” memorize this, it's literally the entire personality of the function:

  • 0 β€” success, we slayed, everything's fine πŸ‘‘
  • -EINVAL β€” the GPIO port is invalid, or it can't be initialized. Not great, not terrible, but definitely not a slay 😭
ngl if you get -EINVAL back, something about your GPIO port is off β€” either it's invalid or it just won't initialize. No cap.

And okay, buckle up bestie, because this cross-reference list is long β€” but every single one of these is iconic in its own way, so here we go:

Like I said. Iconic. All of them. πŸ’€βœ¨
