I haven't deeply reviewed at all, but I already get two problems when
compile testing these patches. I can fix them up if nothing else needs
fixing.

drivers/clk/analogbits/wrpll-cln28hpc.c:165 __wrpll_calc_divq() warn: should 'target_rate << divq' be a 64 bit type?
drivers/clk/sifive/fu540-prci.c:214:16: error: return expression in void function
