[PATCH] dt-binding: gpio: publish binding IDs under dual license

[PATCH] dt-binding: gpio: publish binding IDs under dual license

[Etienne Carriere]

Changes gpio.h DT binding header file to be published under GPLv2 or
BSD-3-Clause license terms. This change allows these GPIO generic
bindings header file to be used in software components as bootloaders
and OSes that are not published under GPLv2 terms.

All contributors to gpio.h file in copy.

Why BSD-3 clause? Bindings are expected to be "OR BSD-2-Clause".

We have NVIDIA permission for anything in bindings and NVIDIA
relicensed the irq headers, so I think it shouldn't be a problem.

FYI, There is blanket approval from Linaro to relicense DT files.

I don't think a blank line is copyrightable.

Fair, 2-clause seems more used. Thanks.
I'll send a v2.
