l3_noc module loses context during both DS0 and RTC+DDR in self refresh modes.
This causes the previously masked l3 interrupts to trigger and the software
book keeping assumes the interrupts are masked and does nothing to mask.
This software/hardware out of sync leads to back to back l3 interrupts
and eventually causes a hang. Hence adding resume hook to restore the
mask registers based on the book keeping variables
Keerthy (2):
bus: omap_l3_noc: Add resume hook to restore context
bus: omap_l3_noc: Correct returning IRQ_HANDLED unconditionally in
the irq handler
