could you please put the new file under a gpl2+x11 dual license?
See the firefly dts files for an example.

Relicensing the of the already existing files is somewhere on my todo list, but
but at least we shouldn't introduce new restricted files at this point :-) .

Licensing with a more permissible license is necessary so that other projects
can use our dts files too (like the BSDs) and the gpl2 + x11 dual license is
the current agreed upon combination.

only for my peace of mind, does the board wake again from suspend with these
rk808 settings? I.e. while I my rk3288-evb-rk808 wakes sucessfully, I haven't
been able to wake an act8846 based board (firefly) yet.

pwrbtn needs one indentation more.

Also please sort alphabetically ... "ak8963" before "buttons"

in general looks good. Because of the license issue I need you to submit a v2,
otherwise I could have fixed the small nitpicks myself.
