Subject: Re: [PATCH v3 1/3] ARM: dts: qcom: Add binding for the qcom coincell
 charger

Greg,

At this point I've got Reviewed-by from Rob on the binding and dts bits,
and Reviewed-by from Andy Gross on the complete patch series (v3).

I believe I've addressed all issues raised. Can you please add this
(v3) to drivers/misc?

Let me know if you want me to re-send anything.

Thanks very much.
