🦋 ARGUMENTS 🦋

• void — no arguments, bestie. nothing to pass, nothing to worry about. it takes zero (0) things. queen behaviour honestly 👑

✨ DESCRIPTION ✨

so what does it actually do? it initializes all powerdomain and clockdomain target states and all PRCM settings. that's the whole vibe check — every powerdomain target state, every clockdomain target state, and all the PRCM settings get set up. main character energy for your power management, fr fr 🔥
