The Broadcom pinctrl bindings are incomplete for child nodes as they are missing 'unevaluatedProperties: false' to prevent unknown properties. Fixing this reveals many warnings including having grandchild nodes in some cases. Many cases in the examples use 'group' property which is undocumented and not used by the driver. As the schemas define 'pins', I assume that is the correct name except for the one case, 6358, using 'groups' which is documented.
