STRUCT PCS_DATA(9)

🎀 struct pcs_data(9) 🎀

okay bestie, welcome to the Kernel API Manual ✨ — yes fr fr, this is the actual kernel docs, and this page is about one lil struct that's basically the sidekick holding the pinctrl framework's stuff together 💅

---

💖 NAME 💖

struct pcs_data — a wrapper for the data that the pinctrl framework needs 🫶 like, it's the cute little bag that carries the things ✨

---

🌸 SYNOPSIS 🌸

struct pcs_data {
    struct pinctrl_pin_desc *pa;
    int cur;
 };

that's it, that's the whole struct, no cap 💀 — two members and she's done, main character energy honestly 👑

---

🦋 Members 🦋

• pa — the pindesc array 🍓 (yeah, literally the array of pin descriptors)
• cur — the index pointing at the current element 🎯 like a little bookmark saying "we're here rn"

---

💜 Description 💜

REVISIT: we should be able to drop this eventually 😭 — the idea is to add support for registering pins individually in the pinctrl framework, specifically for those drivers that don't need a static array. so like, one day this wrapper can retire and live its best life 🌈 periodt.
