With the YAML conversion somehow "assigned-xxx" properties where added. If a proper clock is added to the cru node these properties are no longer needed, so removed them. With the conversion of rockchip,rk3399-cru.txt a table with external clocks was copied. Include these clocks into the schema. Add clocks and clocks-names to example and make them a requirement. Reorder/restyle so that this file is line with the other Rockchip CRU bindings.
