NVMEM real world need for write-only entries

[Nicholas Johnson]

Hi Srinivas,

I have been talking to Mika Westerberg who maintains the Linux 
Thunderbolt driver and it has become apparent that the ability to create 
NVMEM entries with write-only would be of great usefulness for the Linux 
Thunderbolt driver.

Upon visual inspection, it does not appear that it is possible to create 
a NVMEM as write-only, as of this time.

Is this something you would be interested in / willing looking into with 
us?

I could possibly offer a solution / proof of concept patch to add 
write-only support, but without prior discussion, any such efforts would 
likely go astray.

Thank you!

Kind regards,
Nicholas Johnson
