of_clk_add_hw_provider(9)

👑 of_clk_add_hw_provider(9) 👑

okay bestie, welcome to of_clk_add_hw_provider(9) from the Kernel API Manual — this is the one where you register a clock provider for a node, and honestly? iconic behavior. ✨

🎀 NAME 🎀

of_clk_add_hw_provider — the function that registers a clock provider for a node. periodt. 💅

💖 SYNOPSIS 💖

the signature is literally this, don’t let the line break scare you:

int of_clk_add_hw_provider (struct device_node *np , struct clk_hw
*(*get)(struct of_phandle_args *clkspec, void *data) , void *data );

✨ ARGUMENTS ✨

• np — device node pointer associated with the clock provider. that’s the node bestie 🫶
• get — callback for decoding clk_hw. yes, the callback is called get, keep up 💖
• data — context pointer for the get callback. it’s giving “here’s the data you need” energy 🎀
