omap4_prmin...set_asserted(9)

🎀 omap4_prmin...set_asserted(9) 🎀

Ok so bestie, we're in the Kernel API Manual today and this one is a little function with a very long name and honestly lowkey a lot of mystery in its arguments. Stay with me, it's literally so simple once you clock what it does 💅

✨ NAME ✨

omap4_prminst_is_hardreset_asserted — she reads the HW reset line state of submodules contained in the hwmod module. That's it, that's the job. A little peek at the reset line, no cap 👑

🌸 SYNOPSIS 🌸

int omap4_prminst_is_hardreset_asserted (u8 shift , u8 part , s16 inst ,
       u16 rstctrl_offs );

🦋 ARGUMENTS 🦋

• shift — the register bit shift corresponding to the reset line you wanna check. This one is actually described, unlike her friends 💀
• part — -- undescribed -- 🫠 the manpage really just leaves her out here with no explanation
• inst — -- undescribed -- 🙈 same energy, no description, we simply do not know
• rstctrl_offs — -- undescribed -- 😭 iconic of the docs to say nothing actually

ngl bestie, three of the four arguments are literally just -- undescribed -- in the source page. I'm not gonna invent lore for them, that would be lying and lying is not the vibe ✋

💖 DESCRIPTION 💖

So here's the tea, and it's genuinely short:

She returns 1 if the (sub)module hardreset line is currently asserted, 0 if the (sub)module hardreset line is not currently asserted, or -EINVAL upon parameter error. That's the whole personality. Read the line, tell you if it's asserted or not, get mad politely with -EINVAL if you hand her bad params 🌈

It's giving "simple function, complicated name," and honestly? We respect it 💜

And that's the whole page, bestie! This lil' cutie lives in ./arch/arm/mach-omap2, the version/date on the tin is October 2026, and the page signs off as omap4_prmin...set_asserted(9) — yes the footer abbreviates her name, we don't ask questions, we just slay 🎀✨👑
