Subject: [PATCH 0/3] clk: add driver for the SiFive FU540 PRCI and PLLs it controls

Add a driver for the SiFive FU540 PRCI IP block, which handles clock and
some device reset control for the SiFive FU540 chip.  Also add a driver-
independent library for the Analog Bits Wide-Range PLL (WRPLL), used by
the PRCI driver to monitor and control the WRPLL instances on the FU540
chip.

It's been a long time since I've worked on Linux clock code, so Mike &
Stephen, I'd appreciate a close look at the PRCI driver to make sure
what it's doing makes sense.

Boot-tested on a SiFive HiFive Unleashed board.  COREPLL rate changes
and notification were also tested on the same board.
