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.
