Freescale has been part of NXP for a while, so it might make sense to
merge the freescale and nxp directories. I can't speak for
NXP-the-company, so that's just my view as a bystander.

Maybe we should wait for the market consolidation to end so we can put
all the files in a single subfolder?

this would save us from all the bikeshedding ;)

The Kirkwood family should probably be sorted into Marvell.

 create mode 100644 arch/arm/boot/dts/layerscape/Makefile
 rename arch/arm/boot/dts/{ => layerscape}/ls1021a-moxa-uc-8410a.dts (100%)
 rename arch/arm/boot/dts/{ => layerscape}/ls1021a-qds.dts (100%)
 rename arch/arm/boot/dts/{ => layerscape}/ls1021a-tsn.dts (100%)
 rename arch/arm/boot/dts/{ => layerscape}/ls1021a-twr.dts (100%)
 rename arch/arm/boot/dts/{ => layerscape}/ls1021a.dtsi (100%)

The Layerscape family is part of Freescale/NXP.

quoted

 create mode 120000 arch/arm/boot/dts/nxp/armv7-m.dtsi

armv7-m.dtsi is a bit confusing, because it contains a few devices at
fixed addresses, so it looks vendor-specific at a first glance into the
file. However, if it is actually as vendor-neutral as the name implies,
I think it should live dts/ directly, rather than in vendor
subdirectories.

quoted

 rename arch/arm/boot/dts/{ => nxp}/lpc18xx.dtsi (100%)

Here we have the NXP LPCxxxx family, which is AFAIK unrelated to the
i.MX family (and thus the bulk of the Freescale legacy).

quoted

 create mode 100644 arch/arm/boot/dts/vybrid/Makefile

Vybrid is another chip family of NXP, with a good deal of Freescale
legacy in it as evidenced by the "fsl," prefix in the devicetrees.



Thanks,
Jonathan
