# 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.
