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
