Patches for the iMX7ULP platform are already available [1]. Thanks
Alexandre Bailon!

The interconnect API seems to be also a good fit for Nvidia SoCs. There
is an ongoing discussion about implementing an interconnect provider
driver for Tegra [2]. Thanks Thierry and Krishna!

In addition of the above, i also checked privately with a few other SoC
maintainers and made them aware of these patches. Some are not ready for
upstream yet, but the feedback was positive and i expect more SoCs to
make use of this in the future.

BR,
Georgi
