Here's this patch updated with the above removed.
Ok. I fixed up Mike's email in case he wants to look at it. Looks fine
to me though.

Subject: [PATCH] ARM: OMAP2+: Add support for initializing dm814x clocks
Let's add a minimal clocks for dm814x to get it booted. This is
mostly a placeholder and relies on the PLLs being on from the
bootloader.
Note that the divider clocks work the same way as on dm816x and
am335x.
