mv88e6352_g2...pio_get_data(9)

💅 NAME

okay so bestie, gather round — this one is mv88e6352_g2_scratch_gpio_get_data, and it's literally the function that gets data on gpio pin. that's it, that's the whole vibe. it's a kernel API thing from the Kernel API Manual, and it's giving "tiny helper, big responsibilities" ✨

---

✨ SYNOPSIS

int mv88e6352_g2_scratch_gpio_get_data (struct mv88e6xxx_chip *chip ,
unsigned int pin );

like, you hand it a chip and a pin, it hands you back a number. no cap, that's the whole transaction 🫶

---

🎀 ARGUMENTS

• chip — chip private data 💖 the main character of this lil call, fr.
• pin — gpio index 🎀 which pin we're snooping on, bestie.

---

🌸 RETURN

0 for low, 1 for high, negative error 😭

so like — 0? low. 1? high. anything negative? that's the error girlies knocking, handle it. 💀
