From: Mark A. Greer mgr...@animalcreek.com
The am35x family of SoCs do not have an IVA so
a parallel set of clockdomain dependencies are
required that are simililar to OMAP3 but without
any IVA dependencies.

Paul, this is a respin of
[PATCH 08/12] arm: omap3: am35x: Fix clockdomain dependencies
with your comments [hopefully] addressed. I'm breaking that long series
into smaller pieces because most of them really weren't related.
