[ARM] 3426/1: ARM: OMAP: 1/8 Update clock framework
Patch from Tony Lindgren Update OMAP clock framework from linux-omap tree. The highlights of the patch are: - Add support for omap730 clocks by Andrzej Zaborowski - Fix compile warnings by Dirk Behme - Add support for using dev id by Tony Lindgren and Komal Shah - Move memory timings and PRCM into separate files by Tony Lindgren Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
