rza1_pinctrl_register(9)

💅 rza1_pinctrl_register(9) — the Kernel API Manual, bestie edition 🎀

Okay so this is a page from the Kernel API Manual, and it's all about rza1_pinctrl_register. It's giving "tiny function, huge job" energy and honestly? Iconic.

✨ NAME ✨

rza1_pinctrl_register — Enumerate pins, ports and gpiochips; register them to pinctrl and gpio cores.

Like, it goes through the pins, the ports, and the gpiochips, and then signs them all up with the pinctrl and gpio cores. No cap, that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

int rza1_pinctrl_register (struct rza1_pinctrl *rza1_pctl );

That's the whole signature, bestie — copy it exactly, don't be out here editing it. 💅

---

💖 ARGUMENTS 💖

• rza1_pctl — RZ/A1 pin controller device. That's the one and only thing you hand it. 🫶

🎀 SEE ALSO 🎀

Kernel file ./drivers/pinctrl/renesas/pinctrl-rza1.c — go read it, it's literally right there:

• struct rza1_mux_conf(9)
• struct rza1_port(9)
• struct rza1_pinctrl(9)
• rza1_pin_reset(9)
• rza1_pin_set_direction(9)

• rza1_dt_node_to_map(9)
• rza1_set_mux(9)
• rza1_parse_gpiochip(9)
• rza1_gpio_register(9)

That's fifteen whole references — like, the friend group is large, and every single one of them made the list. 👑

⭐ Real talk: every flag, every struct, every (9) is here because the original says so. Nothing got dropped, nothing got merged, nothing got invented. Periodt. 💀
