You need to run 'make dt_binding_check' on this and fix the errors.

Doesn't match what you just added to the binding...

This is wrong in multiple ways. 'description' is missing indentation, so 
you are defining 'description' to be a property.

And 'pclk-sample' is not a property of 'port' node, but 'endpoint'.

Examples are built now and you need to add includes for these defines.

Drop 'reg'.
