💖 rza1_gpio_register(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ this one is all about rza1_gpio_register, and yes it's giving very niche-kernel-girlie energy but we're gonna slay it together 🫶

---

🌸 NAME 🌸

rza1_gpio_register — parse DT to collect gpio-chips and gpio-ranges 💅

like, it goes through the device tree and gathers up the gpio-chips and gpio-ranges. no cap, that's literally the whole vibe.

---

✨ SYNOPSIS ✨

int rza1_gpio_register (struct rza1_pinctrl *rza1_pctl );

---

🎀 ARGUMENTS 🎀

• rza1_pctl — the RZ/A1 pin controller device 🦋

that's the one and only argument, bestie. it's the pin controller device for RZ/A1, and the function needs it to do its little DT-parsing thing.
