From 21094ba5c1f4b15df096e8f6247a50b6ab57c869 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Fri, 6 Sep 2019 19:06:01 +0200 Subject: arm64: dts: zii-ultra: fix ARM regulator states The GPIO controlled regulator for the ARM power supply is supplying the higher voltage when the GPIO is driven high. This is opposite to the similar regulator setup on the EVK board and is impacting stability of the board as the ARM domain has been supplied with a too low voltage when to faster OPPs are in use.
