From: Paul Walmsley <paul@pwsan.com> PM_WKST register contents should be ANDed with the contents of the MPUGRPSEL registers. Otherwise the MPU PRCM interrupt handler could wind up clearing wakeup events meant for the IVA PRCM interrupt handler. For a production version of this patch, we should not read MPUGRPSEL from the PRM, since those reads are very slow; rather, we should use a cached version from struct powerdomain (not yet implemented) --- arch/arm/mach-omap2/pm34xx.c | 3 +++ 1 files changed, 3 insertions(+), 0 deletions(-)
