I forwarded patch 00 to the IIO list and Jonathan Cameron,
and let's page Ye Xiang who made a bunch of contributions
from Intel's side to IIO directly. (Hi Ye, please check this concept
if you have time!)

The actually most important target group would be people
doing things like sensor fusion where a common timebase is
important, I don't know who does really, but Sandeep Singh from
AMD has contributed the AMD Sensor Fusion hub in
drivers/hid/amd-sfh-hid and might know a few things about this
though I don't think SFH would need this directly.
https://en.wikipedia.org/wiki/Sensor_fusion

Also Paging Drew Fustini, who knows a lot of maker and tinker
people, he might know a bit about this or know someone who
knows.

Yours,
Linus Walleij
