Ok, I can update fsl-quadspi.txt to include an example for describing
the flash devices.

As far as I can see all DTs that use fsl-quadspi have a reg property
in the SPI flash sub-nodes:

arch/arm/boot/dts/imx6ul-14x14-evk.dts
arch/arm/boot/dts/imx6sx-sdb.dts
arch/arm/boot/dts/ls1021a-moxa-uc-8410a.dts
arch/arm64/boot/dts/freescale/fsl-ls1046a-qds.dts

Any ideas on how we can properly solve this?
