On a related note, I'm seeing problems when CONFIG_CYGNUS is set but
CONFIG_COMMON_CLK_IPROC is disabled, as that currently leads to a link

I can double check, but it should be on by default when Cygnus is
enabled. If you send me the error, I'll be happy to fix it.


The problem is not that it's off by default but that it can be
disabled, so it breaks some 'make randconfig' builds with this
message:

:(.init.text+0x1d290): undefined reference to `iproc_armpll_setup'

My patch fixes it by always selecting COMMON_CLK_IPROC from
ARCH_BCM_CYGNUS. I wasn't sure whether you want COMMON_CLK_IPROC
to still be user-selectable, so I left that in place. Normally
I'd expect it to be a silent option though, that just gets
implicitly enabled whenever a platform that needs it is built
into the kernel.
COMMON_CLK_IPROC can be a silent option and selected as Arnd has done below.
