[PATCH v1 0/3] PolarFire SoC clock devicetree rework

[Conor Dooley]

From: Conor Dooley <conor.dooley at microchip.com>

Here's a U-Boot implementation of the changes I'm trying to make in
https://lore.kernel.org/all/20241002-private-unequal-33cfa6101338@spud/
that affect how the clocks are described in devicetree for PolarFire
SoC. There's been no complaints about the only part that impacts U-Boot,
so I figured it was time to send patches here.

I've implemented things here in a backwards compatible manner, so that
these changes can be applied now without the relevant devicetree
patches (since the dust has not settled on all aspects of the rework)
and the revised devicetree can make its way into U-Boot via a regular
OF_UPSTREAM update once merged "upstream".

There's minor duplication with Hal's work in patch 3, but I think that's
not particularly important, given it is the addition of a trivial
Makefile we both require:
https://lore.kernel.org/all/20240930155919.111738-1-hal.feng@starfivetech.com

Cheers,
Conor.
