[PATCH v3 00/13] PolarFire SoC reset controller & clock cleanups

[Conor Dooley]

Hey all,

Kinda two things happening in this series, but I sent it together to
ensure the second part would apply correctly.

The first is the reset controller that I promised after discovering the
issue triggered by CONFIG_PM & the phy not coming up correctly. I have
now removed all the messing with resets from clock enable/disable
functions & now use the aux bus to set up a reset controller driver.
Since I needed something to test it, I hooked up the reset for the
Cadence MACB on PolarFire SoC. This was been split into a second series
for v2 (and is now in v6.0-rcN):
https://lore.kernel.org/all/20220704114511.1892332-1-conor.dooley@xxxxxxxxxxxxx/

The second part adds rate control for the MSS PLL clock, followed by
some simplifications to the driver & conversions of some custom structs
to the corresponding structs in the framework.

I'll take the dts patch myself when the rest of this is accepted.
Thanks,
Conor.

Changes since v2:
- reorder reset Makefile/Kconfig entries
- fix a pre-existing bug exposed by clang with this series applied
- add Padmarao who co-authored the original driver to the authors
