What about using simple audio card binding in your device tree instead?

You could pass the simple-audio-card,routing property as described in
Documentation/devicetree/bindings/sound/simple-card.txt

A dts where sgtl5000 is used with simple audio card is
arch/arm/boot/dts/imx7s-warp.dts.

This one does not use simple-audio-card,routing, but at least it gives
you a reference.
