List of child nodes that specify the regulator initialization data.
Child nodes must be named after their hardware counterparts:
buck[1-6], ldoa[1-3], swa1, swb[1-2], and vtt.
Each child node is defined using the standard binding for regulators and
the optional regulator properties defined below.

description: |
Set this if the regulator is factory set with a 25mv step voltage
mapping.

Set this if the output needs to decay, default is for the output
to slew down.
