rza1_parse_pinmux_node(9)

💅 rza1_parse_pinmux_node(9) — the Kernel API Manual glow-up ✨

Okay bestie, listen up 💖 this is a page straight out of the Kernel API Manual, and it's all about rza1_parse_pinmux_node — the little function that parses a pin mux sub-node. Yes, we're doing device tree things, and yes, it's giving main character energy 🎀.

---

🌸 NAME 🌸

rza1_parse_pinmux_node — parse a pin mux sub-node. That's it. That's the vibe. 🦋

---

✨ SYNOPSIS ✨

int rza1_parse_pinmux_node (struct rza1_pinctrl *rza1_pctl , struct
device_node *np , struct rza1_mux_conf *mux_confs , unsigned int *grpins
);

No cap, that's the whole signature. Four arguments, one int return, and a whole lot of pin-muxing potential 🔥.

---

🎀 ARGUMENTS 🎀

• rza1_pctl — the RZ/A1 pin controller device, aka the main character of this whole operation 👑.
• np — the of pmx sub-node. Yep, the device tree node we're parsing, periodt 🌈.
• mux_confs — an array of pin mux configurations that gets filled with all the parsed info. It's literally the output glow-up spot ✨.
• grpins — an array of pin ids to mux. Iconic little list of pins doing their thing 💅.

💀 Warning-ish? No hidden dangers on this page, bestie — just the facts, served fresh. The only thing to watch is making sure your arrays are ready to be filled, because mux_confs and grpins are literally getting the parsed info and pin ids. No invented drama, fr fr.
