That was for the future (I understand making that mistake once with your
v1, but that's v2), no need to resend only for this.

This is an automated instruction, just in case, because many review tags
are being ignored. If you know the process, you can skip it (please do
not feel offended by me posting it here - no bad intentions intended).
If you do not know the process, here is a short explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tag is "received", when
provided in a message replied to you on the mailing list. Tools like b4
can help here. However, there's no need to repost patches *only* to add
the tags. The upstream maintainer will do that for tags received on the
version they apply.

I am using git format-patch only. I think the name of series is changed causing 
the trouble.

Yes, these are name of pins.

Below is the Pin Description from NT36672E Datasheet:

vddi - Power supply to the I/O.
avdd - Positive input analog power for driver IC use.
avee - Negative input analog power for driver IC use.

I could not find datasheet of NT36672A online to compare  the names.

Thanks,
Ritesh

Please use standard email subjects, so with the PATCH keyword in the
title. `git format-patch` helps here to create proper versioned patches.
Another useful tool is b4. Skipping the PATCH keyword makes filtering of
emails more difficult thus making the review process less convenient.

Are these names of pins? Somehow I have troubles believing that NT36672A
and NT36672E have entirely different names for these...

v2: Fixed review comments from Krzysztof
  - renamed to novatek,nt36672e, since the binding is for the IC and
not the panel.
  - moved additionalProperties after required.
