Hi all,
After merging the net-next tree, today's linux-next build (powerpc
allyesconfig) failed like this:

CONFIG_COMMON_CLK is not set for this build.
I have reverted that commit for today.

I am still reverting that commit. Has this problem been fixed in some
subtle way?

I don't think so. I'm assuming something like this is necessary

at a minimum, though it may be saner to #ifdef support for the SiFive clock
driver as that's only useful on some systems. Assuming I can reproduce the
build failure (which shouldn't be too hard), I'll send out a patch that adds a
Kconfig for the FU540 clock driver to avoid adding a COMMON_CLK dependency for
all MACB systems.
