There are a lot of vague hints that VDD_HIGH_IN needs to be powered on before the core voltages of the SoloX (VDD_ARM_IN and VDD_SOC_IN) in data sheets (4.2.1 of the IMXSXCEC.pdf document) and also in the design of the SoloX Sabre Board (using the F6 version of the PMIC).  Yet, it isn't specifically called out.  Does VDD_HIGH_IN need to be powered before the core voltages (VDD_ARM_IN and VDD_SOC_IN)?
