The ordering of these patches is a bit weird with this binding first and 
then the rest of the bindings later.

Also switched my linux-arm-msm email recently so only got the first 
patch with my RB in my Linaro inbox.

Suggest as standard practice when you get review feedback to CC previous 
reviewers on all patches in subsequent series, especially if you are 
picking up an RB on one of those patches.

TL;DR please cc me on V3.
