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.

IIUC these there aren't bisectable: the bindings change will break builds of the DTs and drivers. I'm not sure what's generally the way to go with these, but I always try to avoid broken builds in the middle of patch sets.
Aside from that this generally looks good to me, but the DT and clock folks are probably a better bet for a proper review here. Happy to take this through the RISC-V tree, but IMO it's a better candidate for the clock tree so
