+  st,alert-polarity-active-high:
+    description: Default value is 0 which configures the normal polarity of the ALERT pin, being active low open-drain.
+      Setting this to 1 configures the polarity of the ALERT pin to be inverted and active high open-drain.
+      Specify this property to set the alert polarity to active-high.
