NAK for two reasons (stated many times during review):
1. There is no way driver code can depend on DTS, unless you fix
something serious but nothing is explained about that serious fix in
commit msg.
Please ignore this series as the main patch was missing in this series,
I will resend this after adding missing patch shortly, currently facing
issues with git config on my system. If you look in to v1 patch there is
driver patch which is missing in this series. I will fix it next series.
2. There are no such properties. It does not look like you tested the
DTS against bindings. Please run `make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).
The property is added recently in to the dtschema in github repo, I
added the pull request details in the cover letter, I will add the
github link as part of the comment section for this patch in next
series.
