Subject: [PATCH v2 2/5] dt-bindings: mfd: da9062: add regulator voltage selection documentation
Date:   Wed, 27 Nov 2019 14:59:29 +0100

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 : The GPIO reference which should be used by the
+    regulator to switch the voltage between active/suspend voltage settings. If
+    the signal is active the active-settings are applied else the suspend
+    settings are applied. Attention: Sharing the same gpio for other purposes
+    or across multiple regulators is possible but the gpio settings must be the
+    same. Also the gpio phandle must refer to the mfd root node other gpios are
+    not allowed and make no sense.

 - 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.
