clk_hw_get_...nabled_kunit(9)

💅 clk_hw_get_clk_prepared_enabled_kunit 💅

okay so bestie, this is a page straight out of the Kernel API Manual and it's lowkey one of my faves because it does so much for you and asks for basically nothing back. it's clk_hw_get_clk_prepared_enabled_kunit(9) — yes the name is a whole mouthful, we're gonna get through it together 🫶

---

✨ NAME ✨

clk_hw_get_clk_prepared_enabled_kunit — a test helper that does managed clk_hw_get_clk() plus clk_prepare_enable(), and cleans up after itself like the responsible icon it is 🎀

---

🌸 SYNOPSIS 🌸

struct clk * clk_hw_get_clk_prepared_enabled_kunit (struct kunit *test ,
struct clk_hw *hw , const char *con_id );

---

🦋 ARGUMENTS 🦋

• test — the test context, aka the main character of this whole situation 👑
• hw — the clk_hw associated with the clk being consumed, it's giving "the source of truth" energy
• con_id — the connection ID string on device, iykyk

---

⭐ DESCRIPTION ⭐

so literally, it's just like this:

struct clk *clk = clk_hw_get_clk(...);
clk_prepare_enable(clk);

...except — and this is the slay part — the clk is managed by the test case. it gets automatically disabled and unprepared with clk_disable_unprepare, and put with clk_put, after the test case concludes. no manual teardown, no messy leftover state, no cap. you just vibe and the cleanup happens for you 💖

---

🔥 RETURN 🔥

a new clk consumer that is prepared and enabled ✨ — or ERR_PTR on failure 😭 (check for that one, bestie, fr fr)

mwah 💋 that's the page! this little gem lives over in ./drivers/clk, it's dated October 2026, and the manual calls it clk_hw_get_...nabled_kunit(9) (yes, still abbreviated, we don't make the rules). see you in the next test case, bestie 🌈💜
