Subject: [RFC] dt-bindings: pinctrl: brcm: Ensure all child node properties are documented
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.
Signed-off-by: Rob Herring <robh@...nel.org>

This recursive schema requires a fix not yet committed in dtschema.
I'm looking for feedback on whether group->pins or group->groups is the
right fix here. There's more warnings with this change in the gpio-sysctl
bindings.
