License for ARM device tree file

[Li Leo]

Hi All,

I saw some discussion going on last year about the permissive license to be used in ARM device tree files.  I know a lot of files have been changed to use GPLv2/X11 license.  But may I know if GPLv2/BSD 3-clause dual license is still a valid license to use in ARM device tree files.  It has been our standard permissive license used for a long time in many components like device trees in Power architecture.

Regards,
Leo
