42# We would typically use unevaluatedProperties here but that has the
43# downside that all the properties in the common bindings become valid
44# for all chip generations. In this case, however, we want the per-SoC
45# bindings to be able to override which of the common properties are
46# allowed, since not all pinmux generations support the same sets of
47# properties. This way, the common bindings define the format of the
48# properties but the per-SoC bindings define which of them apply to a
49# given chip.
