Subject: [PATCH] arm64: dts: imx8mm-kontron: Set lower limit of VDD_SNVS to 800 mV
Git-commit: 256a24eba7f897c817fb0103dac73467d3789202
Patch-mainline: v5.15
References: stable-5.14.16

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.
