Okay, this makes sense, I can move this documentation to
Documentation/bindings/mfd/qcom,pm8xxx.txt where the PMIC binding
currently is.

Note that this does introduce a dependency on Lee Jones' mfd tree, where
DT support for the parent pm8921 driver is pending for 3.15.

Andrew, how would you prefer I proceed? Would you like me to respin
this patch? The whole series? An incremental patch?

Thanks,
Josh
