Subject[PATCH v1] arm64: dts: imx8mm: fix missing pgc_vpu_* power domain parent
Date
From: Vitor Soares <vitor.soares@toradex.com>

The pgc_vpu_* nodes miss the reference to the power domain parent,
leading the system to hang during the resume.

As these PU domains are nested inside the vpumix domain, let's reference
it accordingly. After this change, the suspend/resume is working.
