[PATCH] ARM: EXYNOS5: Fix kernel dump in AFTR idle mode

2013-04-29 Thread Inderpal Singh
The kernel crashes while resuming from AFTR idle mode. It happens because L2 cache was not going into retention state. This patch configures the USE_RETENTION bit of ARM_L2_OPTION register so that it does not depend on MANUAL_L2RSTDISABLE_CONTROL of ARM_COMMON_OPTION register for L2RSTDISABLE sign
