am33xx_prm_i...set_asserted(9)

💅 am33xx_prm_is_hardreset_asserted ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — this is the page for am33xx_prm_is_hardreset_asserted, and no cap, it's literally just a vibe check for a reset line 🌸

---

🦋 NAME 🦋

am33xx_prm_is_hardreset_asserted — read the HW reset line state of submodules contained in the hwmod module 💖

like, is the reset line up right now or not? that's the whole gig ✨

---

🧚 SYNOPSIS 🧚

int am33xx_prm_is_hardreset_asserted (u8 shift , u8 part , s16 inst ,
u16 rstctrl_offs );

it's giving "small function, big feelings" 😭 and yes, it returns an int, as it should 👑

---

🌈 ARGUMENTS 🌈

• shift — the register bit shift corresponding to the reset line to check 🔍 like, which bit are we peeking at, bestie
• part — PRM partition, ignored for AM33xx 🙈 yeah she's just there for the vibes on this one
• inst — CM instance register offset (the *_INST macro) 📍
• rstctrl_offs — RM_RSTCTRL register address offset for this module 🎯

ngl, part is the friend who shows up to the group chat and contributes nothing. iconic behavior, but the AM33xx literally does not use it 💀

---

👑 DESCRIPTION 👑

okay so here's the tea ☕ this returns:

• 1 — if the (sub)module hardreset line is currently asserted 🔥 (yes bestie, reset is ON)
• 0 — if the (sub)module hardreset line is not currently asserted 🌸 (nah, it's off)
• -EINVAL — upon parameter error 😭 like if you handed it something cursed

that's it, that's the whole plot. main character energy, minimal screen time 💅
