[ARM] 3430/1: ARM: OMAP: 5/8 Update PM
Patch from Tony Lindgren Update OMAP PM code from linux-omap tree: - Move PM code from plat-omap to mach-omap1 and mach-omap2 by Tony Lindgren - Add minimal PM support for omap24xx by Tony Lindgren and Richard Woodruff - Misc updates to omap1 PM code by Tuukka Tikkanen et al - Updates to the SRAM code needed for PM and FB by Imre Deak Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
