The function first check the status to see if the regulator is already enabled it then get the voltage to check if it is in a acceptable range and then enables it. This will be either called from the regnode_init method (if it's needed by the platform) or by a SYSINIT at SI_SUB_LAST Reviewed by: mmel MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D22106

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
