devm_clk_register(9)

💅 devm_clk_register(9) 💅

okay so we're in the Kernel API Manual, and this page is all about devm_clk_register(9) — the resource-managed clk_register() situation. Let's get into it, bestie 💖

---

🎀 NAME 🎀

devm_clk_register — resource managed clk_register() ✨

---

🌸 SYNOPSIS 🌸

struct clk * devm_clk_register (struct device *dev , struct clk_hw *hw
);

---

🦋 ARGUMENTS 🦋

• dev — the device that is registering this clock. She's the one filing the paperwork 💅
• hw — link to hardware-specific clock data. This is the hardware lore 🧚

---

🔥 DESCRIPTION 🔥

Managed clk_register. This function is deprecated — like, for real — so use devm_clk_hw_register instead, bestie. No cap.

Clocks returned from this function are automatically clk_unregistered on driver detach. See clk_register for more information. iykyk 💖

⚠️ deprecated alert: devm_clk_register is still here, but the manual is literally telling you to use devm_clk_hw_register instead. Periodt.
