Ok, thanks for confirming.

And thanks for confirming that we still want to keep all of these.

One thing I'd really like to see for the ep93xx is to have it
use the COMMON_CLK interfaces. I have patches for OMAP1
that I need to finalize, and then this one will be the last ARM
platform without it. I also still hope we can eventually get ep93xx
into multiplatform build.
