reset_control_deassert(9)

📦 version 7.3.1, in nixpkgs unstable

✨ reset_control_deassert — the deassert girlies have arrived 💅

Okay so real talk, bestie: this is a page from the Kernel API Manual, and it's about letting go of a reset line. Like un-clenching. Releasing the hold. Giving the hardware permission to live its truth. 🦋

🌸 SYNOPSIS 🌸

int reset_control_deassert (struct reset_control *rstc );

That's it. That's the whole vibe. One function, one pointer, one int coming back at you.

🎀 ARGUMENTS 🎀

  • rstc — the reset controller. Your main character. The thing you're about to un-reset. 🔥

💖 DESCRIPTION 💖

So after you call this function, the reset is, like... guaranteed to be deasserted. Not "probably". Not "fingers crossed". Guaranteed. Slay. ✨

But bestie, read this part twice: consumers must not use reset_control_reset on shared reset lines when reset_control_(de)assert has been used. That's not a suggestion, that's the rules. Don't be that person. 💀

And here's the cute part — if rstc is NULL, it's an optional reset, and the function will just return 0. No drama, no crash, no nothing. It just vibes and heads out. 🫶
