From 2b2f106eb55276a60a89ac27a52d0d738b57a546 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Sat, 2 Oct 2021 02:59:37 +0200 Subject: Revert "soc: imx: gpcv2: move reset assert after requesting domain power up" This reverts commit a77ebdd9f553. It turns out that the VPU domain has no different requirements, even though the downstream ATF implementation seems to suggest otherwise. Powering on the domain with the reset asserted works fine. As the changed sequence has caused sporadic issues with the GPU domains, just revert the change to go back to the working sequence.
