Subject: ARM: dts: Set VAUX1 and VAUX4 to 3.0V and 1.8V respectively

ARM: dts: Set VAUX1 and VAUX4 to 3.0V and 1.8V respectively

The development kit schematic expects VAUX1 to be 3.0V.  Most users use the development kit as a reference.
The development kit schematic expects VAUX4 to be 1.8V.  VAUX4 powers VDDS_CSI2 on processor.  If the voltage is too high it could damage the processor.
If it's too low, it won't work.
