13 For device-tree bindings of other sub-modules refer to the binding documents
14 under the respective sub-system directories.
15 Using regulator-{uv,ov}-{warn,error,protection}-microvolt requires special
16 handling: First, when GP_FB2 is used, it must be ensured that there is no
17 moment where all voltage monitors are disabled. Next, as da9063 only supports
18 UV *and* OV monitoring, both must be set to the same severity and value
19 (0: disable, 1: enable).
