Subject: [PATCH v2 00/12] PolarFire SoC reset controller & clock cleanups

Hey all,
I know I have not sat on the RFC I sent about the aux. bus parts
for too long, but figured I'd just send the whole thing anyway to all
lists etc.

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 has been split into a second series
for v2:
https://lore.kernel.org/all/20220704114511.1892332-1-conor.dooley@microchip.com/

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.

Thanks,
Conor.

Changes since v1:
- split off the net patches
- clk: actually pass the spinlock to the converted dividers & gates
- reset: added a spinlock around RMW access to registers
- reset: switched to BIT(i) macros
- reset: used local copies of some variables as pointed out by Philipp
- reset: dropped the success printout
