This series adds minimal support for Microchip Polar Fire Soc Icicle kit.
It is rebased on v5.10-rc1 and depends on clock support.
Only MMC and ethernet drivers are enabled via this series.
The idea here is to add the foundational patches so that other drivers
can be added to on top of this.

This series has been tested on Qemu and Polar Fire Soc Icicle kit.
The following qemu series is necessary to test it on Qemu.

The series can also be found at the following github repo.

I noticed the latest version of mmc driver[2] hangs on the board with
the latest clock driver. That's why, I have tested with the old clock
driver available in the above github repo.

OK, I guess that's why it's an RFC?

Looks like this one hasn't been merged yet. IDK if something is broken with my
mail client but I'm not seeing any github repos. If this depends on
not-yet-merged drivers then it's certainly RFC material, but aside from the DT
stuff (which should be straight-forward) it seems fine to me.

Since you posted this an an RFC I'm going to assume you're going to re-spin it.

Thanks!
