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?

seems like it should only be "jedec,spi-nor" anyway:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=10a6a6975691775bbcc677a04c6fd3120b5c1160
I'll send a v2 series. There were updates to the sound node in the
meantime.
