Nope. This clock is really specific to only the s3c2443. There is only one
hsmmc clock that is identical on both the s3c2443 and s3c2416/2450 and this
one already is in common-s3c2443.c .
common-s3c2443.c was meant for stuff common to s3c2443 _and newer_, i.e.
common clocks and so on.

yeah, we did cut it quite close :-), but it also doesn't seem to have produced
much fall-out. I moved my s3c2416 based development code to 3.4-rc1 without
major hickups.
Getting rid of the remaining mach-directories and also the plat-s3c24xx would
be good. But I'm not sure what you would want to change in mach-s3c24xx
directory itself.
I don't know the earlier SoCs, but the s3c2443 and s3c2416/2450 SoCs currently
don't have redundancies and in the current layout it's quite easy to
understand what belongs to which SoC.
