ARM: Rework omap suspend_late()/resume_early()
This patch reworks platform driver power management code for omap drivers using late/early legacy callbacks. The callbacks are converted for CONFIG_SUSPEND like this: suspend_late() -> suspend_noirq() resume_early() -> resume_noirq() Signed-off-by: Magnus Damm <damm@igel.co.jp> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Acked-by: Pavel Machek <pavel@ucw.cz> Signed-off-by: Rafael J.
