Minor nit, s/suspend-opp/suspend_opp
and here is updated patch
From: Viresh Kumar viresh.kumar@linaro.org Date: Wed, 20 May 2015 08:27:49 +0530 Subject: [PATCH V8] OPP: Add binding for 'opp-suspend'
On few platforms, for power efficiency, we want the device to be configured for a specific OPP while we put the device in suspend state.
Add an optional property in operating-points-v2 bindings for that.

Well, I'm kind of wondering what else has been overlooked here.
Anyway, if I'm supposed to apply this series, I need an ACK from at least one person listed as an "OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS" maintainer. Preferably from Rob.
