[PATCH 7/8] OMAP: clock: Add flags to identify optional clock nodes

From: Rajendra Nayak <hidden>
Date: 2011-06-09 10:54:12
Also in: linux-omap
Subsystem: arm port, omap clock framework support, omap2+ support, the rest · Maintainers: Russell King, Paul Walmsley, Aaro Koskinen, Andreas Kemnade, Kevin Hilman, Roger Quadros, Tony Lindgren, Linus Torvalds

There is a need to identify optional clock nodes in
the clock framework, so some specific sequence
to enable them can be supported, which should be
evident in the subsequent patches.
