Hi Greg,

I was just looking at DTs in -next and noticed that there is a patch
59dfafd03fc (arm64: dts: Add dts files to enable ION on Hi6220 SoC)
which adds at DT doing something for ION.  Are we sure this should be
going into the main production DT?  The bindings haven't been reviewed
as far as I can tell, the matching driver is only in staging and hasn't
been posted upstream.

Thanks,
Mark

Isn't "staging" upstream enough for this?  :)

If not, let me know and I'll be glad to drop this patch, it was on the
list for a while with no objections.

thanks,

I wouldn't have thought so, DTs are supposed to be an ABI so we want
proper review and having had a quick glance this doesn't look like it's
a hardware description so it's not clear to me it should be in DT at all.

Which list?  I did look for the original thread to reply to but it
seemed to be only on the Linux driver project list.

Indeed.

The driver and the binding before that don't really belong either,
I would have NAK'd those on devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, though it
appears I either missed them or they never made it to that list.

>From my PoV there should not be a platform-specific ION binding. If we
need one at all, people should work on the proposed generic binding [1]
or figure out how to do this with the existing reserved-memory bindings.

Thanks,
Mark.

Indeed.

The driver and the binding before that don't really belong either,
I would have NAK'd those on devicetree at vger.kernel.org, though it
appears I either missed them or they never made it to that list.

I posted v2 back in November
(http://article.gmane.org/gmane.linux.drivers.driver-project.devel/80475)
but there wasn't much in the way of review comments. More feedback there
would be appreciated or I can resend.

Thanks,
Laura

I still have those in my queue, but was waiting for someone to chime in
on them.  I guess if no one objected, that means I should accept them?
:)

A resend would be appeciated, as that's easier to reply to.

Before accepting them. I'd rather have some acknowledgement from the DT

at least a better idea than the per platform bindings.
