🌸 clk_is_enabled_when_prepared — Kernel API Manual energy ✨

okay bestie, this is a page straight out of the Kernel API Manual and honestly? it's a little baddie of a function that answers one very specific question for you 💅

✨ NAME ✨

clk_is_enabled_when_prepared — literally tells you if preparing a clock also enables it, no cap.

🦋 SYNOPSIS 🦋

bool clk_is_enabled_when_prepared (struct clk *clk );

🎀 ARGUMENTS 🎀

  • clk — the clock source in question, your main character 🫶

💖 DESCRIPTION 💖

So here's the vibe: this returns true if clk_prepare implicitly enables the clock, which effectively makes clk_enable/clk_disable total no-ops 😭 — and false otherwise.

This is of interest mainly to the power management code, because over there, actually disabling the clock also requires unpreparing it for anything to have any material effect. like, the unprepare is doing the heavy lifting fr fr.

⚠️ Regardless of the value returned here, the caller must always invoke clk_enable or clk_prepare_enable and counterparts so that the usage counts stay right. no skipping, bestie, the usage counts keep receipts 💀
