Thanks for reminding, Mathieu.
Since this is the second time you remind me to send DT binding related
patches separately, so I may misunderstand your meaning and want to get
clarification to avoid making the same mistake for many times.
Before I remembered in one patch set we need to organise patches with
sending document patch (or document changing patch) ahead and then
followed by the corresponding code change patch. So this can give the
reviewers more clear context; and this also can present the merging
dependency between document change patches and the code change patches.
This is the rule I followed in this patch set and I sent to CoreSight
and DT maintainers (and mailing lists) together.
Please let me know what you think about this? And also welcome
Rob/Mark's suggestions.
Thanks,
Leo Yan
