Subject: [PATCH v2 3/6] arm64: dts: imx8mm-kontron: Set lower limit of VDD_SNVS to 800 mV
From: Frieder Schrempf <frieder.schrempf@...tron.de>
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.
Fixes: 8668d8b2e67f ("arm64: dts: Add the Kontron i.MX8M Mini SoMs and baseboards")

Changes in v2:
* Fix the commit ref in the Fixes tag
* Only set lower limit of regulator as upper limit matches range
im datasheet.
