void s3c_pm_do_restore	(	struct sleep_save *	ptr,
		int	count
	)

s3c_pm_do_restore() - restore register values from the save list. : Pointer to an array of registers. : Size of the ptr array.

Restore the register values saved from s3c_pm_do_save().

Note, we do not use S3C_PMDBG() in here, as the system may not have restore the UARTs state yet

void s3c_pm_do_restore_core	(	struct sleep_save *	ptr,
		int	count
	)

s3c_pm_do_restore_core() - early restore register values from save list.

This is similar to s3c_pm_do_restore() except we try and minimise the side effects of the function in case registers that hardware might need to work has been restored.

WARNING: Do not put any debug in here that may effect memory or use peripherals, as things may be changing!

void s3c_pm_do_save	(	struct sleep_save *	ptr,
		int	count
	)

s3c_pm_do_save() - save a set of registers for restoration on resume. : Pointer to an array of registers. : Size of the ptr array.

Run through the list of registers given, saving their contents in the array for later restoration when we wakeup.
