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