sci_clk_prepare(9)

✨ sci_clk_prepare(9) ✨

okay so real talk, this one's a page from the Kernel API Manual, and it's about sci_clk_prepare — the "prepare (enable) a TI SCI clock" girlie 💅

---

🌸 SYNOPSIS 🌸

int sci_clk_prepare (struct clk_hw *hw );

like, that's the whole vibe. one function, one arg, returns an int 🫶

---

🎀 ARGUMENTS 🎀

• hw — the clock you wanna prepare. that's it, that's the whole parameter. bestie gets prepared 💖

---

💫 DESCRIPTION 💫

so what does it actually do? it prepares a clock so it can be actively used ✨ like, it's waking that clock up and telling it "you're on deck, babe."

and then — this part matters — it returns the SCI protocol status. so the return value isn't just vibes, it's the actual SCI protocol status. iykyk 😭

🦋 SEE ALSO 🦋

the whole friend group, no cap. these are all in the kernel file ./drivers/clk/keystone/sci-clk.c:

• struct sci_clk_provider(9)
• struct sci_clk(9)
• sci_clk_unprepare(9)
• sci_clk_is_prepared(9)
• sci_clk_recalc_rate(9)
• sci_clk_determine_rate(9)
• sci_clk_set_rate(9)
• sci_clk_get_parent(9)
• sci_clk_set_parent(9)
• _sci_clk_build(9)
• sci_clk_get(9)
• ti_sci_clk_probe(9)
• ti_sci_clk_remove(9)

ok but seriously, if you're going in on the clock stuff, read sci_clk_unprepare(9) too — prepare and unprepare are literally a matched set, you can't just do one and ghost the other 🙈
