Subject[PATCH v3 3/6] dt-bindings: mfd: da9062: add regulator voltage selection documentation
Date
Add the documentation which describe the voltage selection gpio support.
This property can be applied to each subnode within the 'regulators'
node so each regulator can be configured differently.

+ Optional regulator device-specific properties:
+ - dlg,vsel-sense-gpios : A GPIO reference to a local general purpose input,
+ the datasheet calls it GPI. The regulator sense the input signal and select
+ the active or suspend voltage settings. If the signal is active the
+ active-settings are applied else the suspend-settings are applied.
+ Attention: Sharing the same GPI for other purposes or across multiple
+ regulators is possible but the polarity setting must equal.
+
- rtc : This node defines settings required for the Real-Time Clock associated
with the DA9062. There are currently no entries in this binding, however
compatible = "dlg,da9062-rtc" should be added if a node is created.
