pinctrl_cou...ex_with_args(9)

💅 pinctrl_count_index_with_args(9) — the NAME section, but make it cute

okay so bestie, welcome to the Kernel API Manual page for pinctrl_cou...ex_with_args(9) (yes the header truncates it, the actual grown-up name is pinctrl_count_index_with_args, iykyk). Official vibe: Count number of elements in a pinctrl entry. That's it, that's the whole job ✨

---

🌸 SYNOPSIS 🌸

int pinctrl_count_index_with_args (const struct device_node *np , const
char *list_name );

she returns an int, she takes two args, she's booked and busy 💅

---

🎀 ARGUMENTS 🎀

• np — pointer to device node with the property 🫶 literally just a pointer to the node that's holding the property, bestie.
• list_name — property that contains the list 📋 the actual name of the property you're digging through.

---

✨ DESCRIPTION ✨

So what she does: counts the number of elements in a pinctrl array — and that array is the specific situation where each entry is an index within the controller plus a number of u32 entries specified for each entry. Two-part entries, one cute little count 🔥

Heads up, no cap: the device_node is always for the parent pin controller device. Always always. Don't come at her with some other node 🙈
