💖 NAME 💖

sci_clk_is_prepared — the little function that tells you whether a TI SCI clock is prepared or not. That's it. That's the vibe check 🌸

🦋 SYNOPSIS 🦋

int sci_clk_is_prepared (struct clk_hw *hw );

like, it returns an int and it takes one struct clk_hw * pointer. simple. iconic. no notes 💅

🍓 ARGUMENTS 🍓

  • hw — the clock you want the status of, bestie. The one we're checking up on. 👀

🔥 DESCRIPTION 🔥

So what does it actually do? It checks if a clock is prepared (enabled) in the hardware. Boots-on-the-ground, actual-silicon reality check, not just a software opinion ✨

And the return value is literally this simple:

  • non-zero → the clock is enabled 🔥 slay
  • zero → it's not 🙈

That's the whole function, fr fr. No cap.

The kernel file where all this lives is ./drivers/clk/keystone/sci-clk.c, and honestly the whole friend group is here too:
