BTW, all clk drivers depends on COMMON_CLK so these won't even be built in
tile or um since that symbol isn't selected there. Or did I misunderstand?

Having said that, I see that enabling COMPILE_TEST will attempt to build
in many archs [0] that I don't have a toolchain to test. So I'm OK if you
drop this patch and sorry for the inconvenience.

[0]:
$ git grep "select COMMON_CLK" arch/ | cut -d '/' -f2 | uniq 
arc
arm
arm64
h8300
microblaze
mips
powerpc
x86
xtensa
