Subject: [PATCH] arm64: dts: imx8mp-verdin: board regulators: add always-on
Date: Thu, 1 Sep 2022 13:04:22 +0200 [thread overview]
Message-ID: <20220901110422.1859621-1-max.oss.09@gmail.com> (raw)
From: Max Krummenacher <max.krummenacher@toradex.com>
These regulators are switched on by HW during power up and can not
be influenced by SW.
Set the always-on property.
