Subject: [RFC PATCH 1/2] dt-bindings: mfd/syscon: Add resets property
Simple syscon devices may require deassertion of a reset signal in order
to access their register set. This change adds the `resets` property from
reset.yaml#/properties/resets (referenced through core.yaml), specifying
a maxItems of 1 for a single (optional) reset descriptor.
This will allow a future change to the syscon driver to implement reset
control.
