Any new compatible needs to be documented.
There is actually no ls1028a board documented ;) I'd add the rdb as well
as the qds to Documentation/devicetree/bindings/arm/fsl.yaml in the next
series. Or is that just for arm and not arm64?

Is "w25q32jw" documented somewhere?
seems like it should only be "jedec,spi-nor" anyway:

I'll send a v2 series. There were updates to the sound node in the
meantime.
