14   Any property defined as part of the core regulator binding, defined in
15   regulator.yaml, can also be used. However a fixed voltage regulator is
16   expected to have the regulator-min-microvolt and regulator-max-microvolt

62       the compatible is chosen to regulator-fixed-clock. The clock binding
63       is mandatory if compatible is chosen to regulator-fixed-clock.
66   power-domains:
70       available if the compatible is chosen to regulator-fixed-domain.
73   required-opps:
77       available if the compatible is chosen to regulator-fixed-domain. The
78       power-domain binding is mandatory if compatible is chosen to
79       regulator-fixed-domain.
