Hi Vdaym,

Am totally confused with this patchset, There is no versioning in any of 
your patches, you always send it with PATCH, please add version so that 
I know which one should I review!

This makes my mailbox totally confused with all the patches with same 
subject prefix!

Please note that maintenance is not my full time job, so please be 
patient and I can try shift gears as an when possible!

This is a NO-NO as onie is not a real provider here, at24 is the actual 
nvmem provider in your case.

Why do you keep changing the total approach here! what is the reasoning 
to do so!
As I said in my last review we were okay with this parser approach!

I don't mind having changes in core as long as it done properly!


thanks,
srini
