I remember, we agree that to control phy cannot be handled in clock part. And didn't say to make some kind of common s5p phy setup/control function? http://lists.infradead.org/pipermail/linux-arm-kernel/2011-January/038038.ht ml I thought it is possible to make it even though some registers is in different place.
