[PATCH] clk: rockchip: Switch dt-binding headers for rk3328 to GPL/X11

[PATCH] clk: rockchip: Switch dt-binding headers for rk3328 to GPL/X11

[Emmanuel Vadot]

Since those files are also needed kernel side, switch their licences
to GPL/X11 so it can be used in BSD kernels.

definitly no objection from me (especially as the file only contains
constant definitions, so copyrightability might be debateable),
but could you:

(1) Adapt all rockchip clock headers in one patch, so we don't do this
    for each header invididually
(2) Do the same for the power/rk3* headers, but in a separate patch
    as this goes through a different tree


Thanks
Heiko

 Sure I can do that, will it be better to wait to have some kind of ack
from someone from rockchip ?

I don't know if China is somehow affected by the xmas season, but from what
I see, right now you only included Elaine (zhangqing-TNX95d0MmH7DzftRWevZcw@public.gmane.org)
but for example not the relevant list (linux-rockchip-IAPFreCvJWM7uuMidbF8XUB+6BGkLq7r@public.gmane.org).

But we also have some other points to clarify in the other subthread
started by Philippe, so it might be best to get the points he made sorted
before as well.

You just poked a big pointy stick in my left eye. It hurts! Why not
use a proper SPDX tag here, like you did below?

Each time such a long legalese is added to the kernel instead of an
SPDX tag there is an endangered animal species that disappears from
the face of the earth for good.  You do not want to bear this grave
responsibility, do you?

Also are you sure Elaine, other contributors and Rockchip Electronics
Co. Ltd. agree to this change?
It might be best if the patch were to come from them directly or at
least you will need proper acks for sure.

What you call X11 is called MIT in SPDX and in Thomas doc patches [1],
e.g. this tag is supposed to match the eyes-poking long legalese
above, this should be instead:

+/* SPDX-License-Identifier: (GPL-2.0+ or MIT) */

Finally if the goal of this proposed license update is usage in
FreeBSD and other BSD kernels, why use MIT as a second license? Would
not a BSD be better and avoid license inflation on the BSD side?

I think it is likely meant to match the license used on the devicetree
files themselfs. For whatever reason the existing combination of
GPL+MIT was the preferred one, so the license inflation is already there
and it might be best to keep to the same combination for the headers
needed by those devicetree files?

 I've just used the same licence present on the DTS file.
 In one file there was just SPDX licence tags so I've keep it this way.

 I don't know if they agree, sending a patch seems the best way to know
for me.

 Right, sorry for that, I'll change that.

 It will probably be better, I honestly don't care. A lot of dts file
and dt headers are already GPL+X11 so I'm just following the common way
of doing things.
