[PATCH 07/17] omap4: pm: CPU1 wakeup workaround form Low power modes

Santosh Shilimkar [off-list ref] writes:

The SGI(Software Generated Interrupts) are not wakeup capable from
low power states. This is known limitation on OMAP4 and needs to be
worked around by using software forced clockdomain wake-up. CPU0 forces
the CPU1 clockdomain to software force wakeup. After the wakeup, CPU1
restores its clockdomain hardware supervised mode.

More details can be found in OMAP4430 TRM - Version J
Section :
	4.3.4.2 Power States of CPU0 and CPU1
