Yeah, you did. Sorry for sending the new versions very fast. Normally I prefer
to keep up with comments so to past a particular maintainer review as fast as
possible without long delays. In my experience the longer you wait, the lesser
maintainers remember about your patchset, the harder for one to continue the
next versions review.
Regarding this patch the brand new version on is v6:
[PATCH v6 02/11] dt-bindings: i2c: Convert DW I2C slave to the DW I2C master example
Could you please find it in your email log? I've left a note there for you about
options what we can do with this case.
