clk_enable(9)

💖 clk_enable(9) — Kernel API Manual ✨

okay so bestie, welcome to the glow-up era of the kernel clock API. this is clk_enable, and no cap, she's the one who tells the system "hey, this clock source needs to be running rn." 🕐💅

---

✨ NAME ✨

clk_enable — inform the system when the clock source should be running. literally her whole job. iconic.

---

🦋 SYNOPSIS 🦋

int clk_enable (struct clk *clk );

---

🎀 ARGUMENTS 🎀

• clk — clock source. that's it. that's the whole argument, and she ate. 👑

---

🌸 DESCRIPTION 🌸

so here's the vibe check: if the clock can't actually be enabled or disabled, this should return success. yeah, for real — no error, just success. that's the rule, don't come for me. 😌

and the tea: this one may be called from atomic contexts. ☕🔥 which is highkey a big deal, so don't be weird about it.

she returns success (0) or a negative errno. that's the two moods. 💀
