Subject: [PATCH 1/3] ARM: dts: rockchip: Move cros-ec-sbs to rk3288-veyron-chromebook-sbs

This moves the cros-ec-sbs dtsi to a new rk3288-veyron-chromebook-sbs
dtsi since it only concerns rk3288 veyron Chromebooks.

Other Chromebooks (such as the tegra124 nyans) also have sbs batteries
and don't use this dtsi, that only makes sense when used with
rk3288-veyron-chromebook anyway.

That isn't true. The gru series (rk3399-based) also uses the
sbs-battery [0]. And while it is currently limited to Rockchip-based
Chromebooks it is nevertheless used on more than one platform, so
the probability is high that it will be used in future series as well.

Also, it might be nice to also include some Chromeos people (there should
be some in the git logs, like Brian who submitted the Gru patches), as they
might be able to provide more detailed input.

That's good to know, but as pointed out, other cros devices are using a sbs
battery without this header, so such a generic name isn't really a good fit.

Note that &charger has to be defined (after my subsequent patches), which it is
for devices that also include rk3288-veyron-chromebook, but not necessarily
others.

Overall, I think having one -sbs dtsi file makes sense here because there is
already a rk3288-veyron-chromebook dtsi that veyron chromebooks use. That file
cannot contain the battery bindings because minnie has a different one and it
would be a bit silly to copy it over all devices. That definitely makes sense.

As for other devices, I don't see why we should have a separate include file for
the battery instead of having it in the device's dts. I think this should be the
case on gru/kevin.

Also maybe not *all* gru-based devices will turn out to use a SBS battery, so it
seems early to include this header in the gru dtsi. One last point, gru/kevin
currently don't define a charger, which will break my subsequent patch (that is
however needed for the veyrons that use this file).

To me, it seems that there's little advantage and major drawbacks in keeping
this file the way it is.

That's a good point, thanks for including them.
