Actually this point was discussed during V2( 
https://lore.kernel.org/patchwork/patch/1406186/#1607321 ).
As far as I understand it is not mandatory to add "qcom,pm7325" as we 
are adding "qcom,spmi-pmic". It is just a good to have change.
I could not find the documentation for pm8350c, pmk8350 and pmr735a as 
well.

The binding patch is applied now.
