[PATCH v2 3/6] arm64: dts: imx8mm-kontron: Set lower limit of VDD_SNVS to 800 mV

From: Frieder Schrempf <hidden>
Date: 2021-10-15 12:49:26
Also in: linux-arm-kernel, lkml, stable
Subsystem: arm/freescale imx / mxc arm architecture, the rest · Maintainers: Frank Li, Sascha Hauer, Linus Torvalds

From: Frieder Schrempf <redacted>

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.
