drivers/clk/sifive, which was added recently doesn't have these changes
and thus the build fails. To reproduce, without installed RISC-V toolchain, try:
./test/emulate.pl --runtime=podman sifive_defconfig
Doing the conversions aren't completely trivial to me, as there are no
clkdev clk_hw helpers ported and I still need to figure out how to use them.
Given that your caches are still hot, could you take a look?
Thanks,
Ahmad
