Hi,

This is the second version of the bq2415x binding documentation. The
only changes since PATCHv1 are a rewording of the property descriptions
as requested by Pavel Machek.

I narrowed down the CCs for this patch, since there were no comments on
PATCHv1 from omap or DT binding guys and Anton has applied the driver changes
already. This patch is intended for 3.14, so that it gets merged together
with the driver changes.

Hi,

It's me again :) Here's another update, which fixes a sentence reported by
Pavel. I also added his Acked-by.

I've seen, that you just sent a pull request for the power supply
tree. Can you please add this patch [0] and send another pull
request? It should go into the kernel together with the bq2415x DT
support patch!

If that is fine with you, I will add this to a 'fixes' branch and send
a pull request
somewhere near -rc2/-rc3. Agreed?
