Regulator nodes should be named to DSVP and DSVN. The
|
||
|
|
definition for each of these nodes is defined using the standard
|
||
|
|
binding for regulators at
|
||
|
|
Documentation/devicetree/bindings/regulator/regulator.txt.
|

|

Datasheet is available at

|
The first one is ENP to enable DSVP, and second one is ENM to enable DSVN.
|
||
|
|
Number of GPIO in the array list could be 1 or 2.
|
||
|
|
If only one gpio is specified, only one gpio used to control ENP/ENM.
|
||
|
|
Else if both are specified, DSVP/DSVN could be controlled individually.
|
||
|
|
If this property not specified, treat both as always-on regulators.
|
||
|
|
|
||
|
|
Property is deprecated. Use enable-gpios in each regulator.
