Subject: [PATCH v2 0/5] Refactor the PRCI driver to reduce the complexity

This patch set tries to improve the PRCI driver to reduce the
complexity, we remove the SoCs C files by putting putting all stuff in
each SoCs header file, and include these SoCs-specific header files in
core of PRCI. It can also avoid the W=1 kernel build warnings about
variable defined but not used [-Wunused-const-variable=], like 'commit
487dc7bb6a0c ("clk: sifive:fu540-prci: Declare static const variable
'prci_clk_fu540' where it's used")' does.

This patch set also contains the dt-bindings and dts change, because
we change the macro name for fu540 and fu740 by adding the prefix
respectively.

Thanks all for your review and suggestions.

Changed in v2:
 - Rebase on v5.17-rc6
 - Add a temporary patch for avoiding breaking git bisect

Zong Li (5):
  clk: sifive: duplicate the macro definitions for the time being
  dt-bindings: change the macro name of prci in header files and example
  riscv: dts: Change the macro name of prci in each device node
  clk: sifive: Add SoCs prefix in each SoCs-dependent data
  clk: sifive: Move all stuff into SoCs header files from C files
