clk_gate_restore_context(9)

✨ clk_gate_restore_context ✨

okay so we're diving into section 9 of the Kernel API Manual today, and honestly? this one is a little sleeper hit. it's giving "quietly saves your whole system" energy 👑

---

🌸 NAME 🌸

clk_gate_restore_context — restore context for poweroff 💤➡️⚡

---

🎀 SYNOPSIS 🎀

void clk_gate_restore_context (struct clk_hw *hw );

no cap, that's the whole signature. one pointer, zero return value.

---

🦋 ARGUMENTS 🦋

• hw — the struct clk_hw pointer of the clock whose state is to be restored. this is your main character right here 🫶

---

💖 DESCRIPTION 💖

okay bestie, so here's the vibe. clk_gate_restore_context enables or disables the gate clocks based on the enable_count. that's the whole personality.

this kicks in for cases where the clock context is lost 😭 — like, the clock forgot what it was doing — and so, based on the enable_count, the clock either needs to be enabled or disabled. that's it, that's the mission.

and the payoff? it helps restore the state of gate clocks ✨ literally putting the vibes back where they belong.

ngl the whole function is basically "check the count, then turn the thing on or off." simple, iconic, effective 💅

go restore those clocks, bestie. periodt. 💅✨
