📦 version 7.3.1, in nixpkgs unstable

💅 omap2_prm_is_hardreset_asserted(9) — like, the Kernel API Manual era 🎀

okay bestie, so this one is a little function from the Kernel API Manual and it's literally just here to check a vibe — specifically, is that hardware reset line asserted or not? no cap, that's the whole gig. let's get into it ✨

✨ NAME ✨

omap2_prm_is_hardreset_asserted — reads the HW reset line state of the submodules that live inside the hwmod module 🫶

🌸 SYNOPSIS 🌸

int omap2_prm_is_hardreset_asserted (u8 shift , u8 part , s16 prm_mod ,
       u16 offset );

🦋 ARGUMENTS 🦋

  • shift — the register bit shift that points at the reset line you wanna check 👀 like, this is the one that actually matters for finding your line.
  • part — the PRM partition. but bestie, it's ignored for OMAP2 💀 don't stress about it there.
  • prm_mod — the PRM submodule base, e.g. CORE_MOD 💖
  • offset — the register offset. also ignored for OMAP2 🙈 so yeah, two of these four are just along for the ride on OMAP2.

💜 DESCRIPTION 💜

okay so real talk, this returns 1 if the (sub)module hardreset line is currently asserted, and 0 if the (sub)module hardreset line is not currently asserted. slay, simple.

but watch out — it returns -EINVAL if you call it while running on a non-OMAP2/3 chip 😭 so like, do a vibe check on your chip first, fr fr.
