Luxul XAP-1510 is an AP device based on BCM4708 SoC. It uses flash
memory connected to the SPI controller.

Looks fine, except one nit:

The ARM SoC maintainer have been asking to utilize a license which is
also BSD compatible, so something along the lines of this one:

arch/arm/boot/dts/bcm911360k.dts

Do you mind respining the patch to include that kind of license header?
Thanks!

I wasn't aware of this neither. Shall we re-license existing DTS files
as well? I'm fine with changing them to BSD compatible.

I'm a bit confused by using BSD license only. Kernel is licensed under
GNU GPL version 2 and if there are some BSD compatible modules, they
use dual licensing model (BSD/GPL). Shouldn't we use BSD/GPL in DTS
files as well then?

As far as I understand the License part you can take code which is
licensed under BSD license and use it in GPL code because you can comply
with the BSD license and also handle it in a way to be GPL compliant at
the same time. You can also make a change to BSD code and license this
change under the GPL, then the complete code (the old one + your change)
is now GPL.

Are the device tree files licensed under BSD license to make it easier
to integrate them into a proprietary boot loader or what is the purpose?

Yes, there could be that, or just making the license compatible with
other OSes like FreeBSD for instace.
