The structure of the NVIDIA Tegra234 common pinmux schema doesn't work for restricting properties because a child node schema can't be extended with additional properties from another schema defining the same child node. The 2 child node schemas are evaluated independently as the schemas are not recursively combined in any way. As the common schema is almost all the child node schema anyways, just remove the parent node from the common schema. Then add 'reg' and adjust the $ref's in the users of the common schema.

# 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.
