Since unit addresses are passed to simple-audio-card,dai-link a corresponding 'reg' property is needed, otherwise dtc complains (when building with W=1) in case someone copies the bindings example into a real dts file:
Warning (unit_address_vs_reg): Node /sound-digital/simple-audio-card,dai-link@0 has a unit name, but no reg property
Improve the example by passing the correct 'reg' properties.
