✨ NAME ✨

zynqmp_clear_pm_state — clears subsystem state 🧹

✨ SYNOPSIS ✨

int zynqmp_clear_pm_state (struct device *dev );

like, that's the whole flex. one function, one arg, no cap 💅

✨ ARGUMENTS ✨

  • dev — device pointer, and its whole job here is logging. that's it. it's giving "I'm just here so I don't get fined" 😭 it gets passed in, it helps with the logs, it minds its business.

✨ DESCRIPTION ✨

so what does it actually do? it clears PM specific data in EL3 and platform firmware ✨ that's the entire vibe. PM data? cleared. in EL3? yes. in platform firmware? also yes. obsessed with the efficiency honestly 🫶

✨ RETURN ✨

it returns a status — either success or error ⭐ so like, check it, don't just assume it slayed 🙈

✨ SEE ALSO ✨

fr fr that's the whole friend group and they all showed up 💀 no one got left on read.

so yeah, that's the page 💖 trust the return status, log through dev, and go clear that state.

mwah 💋
