This node needs to have exactly 3 clocks, according to this 
documentation here in Linux:

Documentation/devicetree/bindings/soc/microchip/atmel,at91rm9200-tcb.yaml

Also the list of required properties contain multiple entries compared 
to your node.

We need to have this node exactly as the one in Linux DT.
