💅 omap_device_deassert_hardreset(9) — a Kernel API Manual moment 🎀

okay so this is from the Kernel API Manual, and bestie, we're talking about omap_device_deassert_hardreset today. pull up a chair, grab a strawberry 🍓, let's get into it.

✨ NAME ✨

omap_device_deassert_hardreset — release a device's hardreset line 🫶

like, let it go. un-clench. release the line.

🌸 SYNOPSIS 🌸

int omap_device_deassert_hardreset (struct platform_device *pdev , const
char *name );

literally the whole vibe in two lines, no cap ✨

🦋 ARGUMENTS 🦋

  • pdev — a struct platform_device * to reset. yeah, that one. the device in question, the main character 👑
  • name — a const char *, the name of the reset line. you gotta tell it which line, iykyk 💅

💖 DESCRIPTION 💖

okay so here's the tea ☕ — this function releases the hardreset line identified by name on the IP blocks associated with the hwmods backing the platform_device pdev. it's giving "let my people go" but for hardware 🔥

the way that this works though: all of the hwmods associated with pdev must have the same hardreset line linked to them, or it's not gonna happen. that's the rule, periodt. every single one, no exceptions 🙈

in the event of any failure, it passes along the return value of omap_hwmod_deassert_hardreset — so if that one's unhappy, you're gonna hear about it directly, no filter. and on success? returns 0. iconic. slay. ✨

🌈 SEE ALSO 🌈

the kernel file lives at ./arch/arm/mach-omap2/omap_device.c — go read it, it's right there bestie 📖

and the whole friend group 💜:

(notice omap_device_assert_hardreset(9) in there? that's the other half of this situationship — assert vs deassert, opposites attract fr fr 😭)

⚠️ quick vibe check: if your hwmods don't all share that same hardreset line, this is not gonna work for you. that's not me being mean, that's just the manpage. 💀

and that's the whole thing, bestie! this gem comes from ./arch/arm/mach-omap2, dated October 2026 — so like, mark your calendar, screenshot it, whatever 💅 see you in the next manpage, muah 🎀💖🧚⭐
