clk_debug_init(9)

✨ NAME ✨

hey bestie, welcome to clk_debug_init(9) from the Kernel API Manual 💖 — short version: clk_debug_init exists to lazily populate the debugfs clk directory.

📞 SYNOPSIS 📞

int clk_debug_init (void );

🫶 ARGUMENTS 🫶

• void — no arguments. that's it, that's the whole list 💅

🌸 DESCRIPTION 🌸

okay so picture this: clks are often initialized very early during boot — before memory can be dynamically allocated, and well before debugfs is setup. this function populates the debugfs clk directory once at boot-time, when we know that debugfs is setup ✨

bestie, real talk: this should only be called once at boot-time. all other clks added dynamically will be done so with clk_debug_register. no cap — don't make it a whole thing 💀
