Subject[PATCH] arm64: dts: imx8mm-beacon: Fix voltages on LDO1 and LDO2
Date
LDO1 and LDO2 settings are wrong and case the voltage to go above the
maximum level of 2.15V permitted by the SoC to 3.0V.

This patch is based on work done on the i.MX8M Mini-EVK which utilizes
the same fix.

Fixes: 593816fa2f35 ("arm64: dts: imx: Add Beacon i.MX8m-Mini development kit")
