Subject: [PATCH v3 0/3] 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.
Boot-tested on a SiFive HiFive Unleashed board, using BBL and the
open-source FSBL with a mainline-focused DTB.
This third version incorporates changes requested by Stephen Boyd
<sboyd@...nel.org> and Rob Herring <robh@...nel.org>.
This patch series is also available, along with the DT macro prerequisite
patch, at:
