✨ ufs_qcom_setup_clocks(9) ✨

okay so bestie, this is a page from the Kernel API Manual, and it's all about one lil' function that turns clocks on and off 🕰️💖

🌸 NAME 🌸

ufs_qcom_setup_clocks — enables/disable clocks

🎀 SYNOPSIS 🎀

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

🦋 ARGUMENTS 🦋

  • hba — the host controller instance, aka the main character here 👑
  • on — if it's true, we enable the clocks; otherwise we disable them. Simple as that, no cap 💅
  • status — either PRE_CHANGE or POST_CHANGE notify. pick your moment bestie ⏰

💜 DESCRIPTION 💜

So here's the tea ☕: there are certain clocks that come from the PHY, which means they gotta be managed together with the controller clocks — and lowkey that's also just better for power saving, fr fr 🌱✨

That's literally why the phy_power_off/on calls live inside ufs_qcom_setup_clocks — so that the PHY's regulators & clks can be turned on/off right along with UFS's clocks. team work makes the dream work 🫶

🔥 RETURN 🔥

0 on success, non-zero on failure. slay when it works, sad girl hours when it doesn't 😭
