Subject: [PATCH v4 0/2] clk: add driver for the SiFive FU540 PRCI and PLLs it controls
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.
This fourth version incorporates changes requested by Stephen Boyd
<sboyd@...nel.org>. The DT bindings patch has been dropped since
Stephen has already queued it.
This patch series is also available, with the binding documentation
patch, at:
https://github.com/sifive/riscv-linux/tree/dev/paulw/prci-v5.1-rc7
Boot-tested on a SiFive HiFive Unleashed board, using BBL and the
open-source FSBL with a mainline-focused DTB, using the following
composite test branch:
