Subject: arm64: dts: imx8mm-kontron: Set lower limit of VDD_SNVS to 800 mV
From: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx>
commit 256a24eba7f897c817fb0103dac73467d3789202 upstream.
According to the datasheet the typical value for VDD_SNVS should be
800 mV, so let's make sure that this is within the range of the
regulator.
