✨ of_hwspin_lock_simple_xlate ✨

okay bestie, so we're deep in the kernel of_hwspin_lock_simple_xlate(9) page today — it's a Kernel API Manual entry, and honestly? it's a tiny little icon that does exactly one thing and does it slay 💅

🌸 NAME 🌸

of_hwspin_lock_simple_xlate — translate hwlock_spec to return a lock id 🎀

---

🦋 SYNOPSIS 🦋

int of_hwspin_lock_simple_xlate (const struct of_phandle_args
*hwlock_spec );

---

💖 ARGUMENTS 💖

• hwlock_spec — the hwlock specifier, fr fr as found in the device tree 🌳

---

⭐ DESCRIPTION ⭐

okay so this one is literally The Simple Translation Function™ — it's designed for hwspinlock platform drivers where the lock specifier length is just 1. that's it. that's the vibe. lowkey minimal, highkey essential 👑

it's the kind of function that doesn't need a whole personality — it just needs to show up and translate. main character energy in a one-line way 🫶

---

🌈 RETURN 🌈

on success you get a relative index of the lock within a specified bank ✨ — and if the specifier cell count is invalid, it's -EINVAL, no cap 💀
