of_clk_get_kunit(9)

💅 of_clk_get_kunit(9)

okay so bestie, welcome to the Kernel API Manual ✨ this one is a tiny little helper that's giving very "test-only, don't @ me" energy and honestly? iconic behavior. let's get into it 🎀

---

✨ NAME ✨

of_clk_get_kunit — the test-managed glow-up of of_clk_get() 🦋

---

🌸 SYNOPSIS 🌸

struct clk * of_clk_get_kunit (struct kunit *test , struct device_node
*np , int index );

like yes, that's the whole signature, no cap 💅

---

💖 ARGUMENTS 💖

• test — the test context 🧪 like, the whole vibe of the test case lives here
• np — the device_node for the clock "consumer" 👀 (yes "consumer" in quotes, the quotes are doing work)
• index — the index in the 'clocks' property of np 🔢

---

👑 DESCRIPTION 👑

so literally just like of_clk_get(), except the clk is managed by the test case — meaning it gets automatically clk_put when the test case concludes 🫶 set it and forget it, she cleans up after herself, main character energy fr fr ✨

---

⭐ RETURN ⭐

a new clk consumer 🎀 or ERR_PTR on failure 😭 (check it bestie, always check it)
