💖 ufs_mtk_setup_clocks(9) 💖

okay so welcome to the Kernel API Manual bestie, today we're looking at ufs_mtk_setup_clocks(9) and honestly? it's giving "small function, big responsibilities". it does exactly one glamorous thing: turns clocks on and off. that's it. that's the gig. 🕐✨

✨ NAME ✨

ufs_mtk_setup_clocks — enables/disable clocks 🎀

like yes the grammar is a little chaotic but the energy is correct, she enables AND she disables, an icon of duality 💅

---

🌸 SYNOPSIS 🌸

int ufs_mtk_setup_clocks (struct ufs_hba *hba , bool on , enum
ufs_notify_change_status status );

three arguments, one int return, zero drama (unless it returns non-zero, then there's some drama 😭)

---

🦋 ARGUMENTS 🦋

• hba — the host controller instance, aka the main character of this whole situation 👑 this is the thing whose clocks you're messing with, so pls be normal about it.
• on — if true, enable the clocks; else disable them. it's a bool, it's literally yes-or-no, no in-between, no "maybe", no "i'll decide later" 🙈
• status — PRE_CHANGE or POST_CHANGE notify 📣 which one you get depends on where in the change you are. before? after? she contains multitudes.

---

⭐ RETURN ⭐

0 on success, non-zero on failure. that's the whole deal. zero = slay, non-zero = something went sideways and you should probably look at it 🔥

lowkey reminder: this page is short because the function is short, not because i'm being lazy. every single detail is here. no cap. 💜

and that's the tea 🍓 this came to you from ./drivers/ufs/host, dated October 2026, and yes that's the actual footer energy, mwah 💋✨
