From 0271b61ba3bb06fff4726951667f46e68412b8c2 Mon Sep 17 00:00:00 2001 From: Benjamin Bara Date: Wed, 5 Apr 2023 19:14:36 +0200 Subject: [PATCH] dt-bindings: mfd: dlg,da9063: document voltage monitoring Document that the da9063 only provides under- *and* over-voltage monitoring in one, and therefore requires both to be configured with the same severity and value. Add an example for clarification.
