If an arch has HAVE_CLK enabled it must provide valid clocks (be it
dummy clocks) for all devices it supports.

So, lets take the theoretical exaple of a unicore32 PUV3

config ARCH_PUV3
        def_bool y
        select CPU_UCV2
        select GENERIC_CLOCKEVENTS
        select HAVE_CLK
        select ARCH_REQUIRE_GPIOLIB
        select ARCH_HAS_CPUFREQ

Seems like this somewhat unknown, to me at least, architecture, also
supports PCI. So i plug in an HP Adaptec AIC8120 SATA host bus adapter
into a spare PCI slot. This uses the Marvell 88SX6041, which the
SATA_MV driver supports.

Should i expect that the unicore32 PUV3 has created a dummy clk for
this case?

Thanks
