description: |
  For device-tree bindings of other sub-modules refer to the binding documents
  under the respective sub-system directories.
  Using regulator-{uv,ov}-{warn,error,protection}-microvolt requires special
  handling: First, when GP_FB2 is used, it must be ensured that there is no
  moment where all voltage monitors are disabled. Next, as da9063 only supports
  UV *and* OV monitoring, both must be set to the same severity and value
  (0: disable, 1: enable).
  Product information for the DA906{3L,3,2,1} devices can be found here:
