ux500-pm: "ApDeepSleep" low power state support
This patch adds the "ApDeepSleep" low power state for the U8500 platform. The ApDeepSleep is the lowest power state, both the core/ape turned off. This low power mode can now be entered/exited through the standard linux PM framework echo mem > /sys/power/state will put the core into the deep sleep state. The system can be woken up from USB insertion, console, RTC events back to the execute mode. This patch - cleans existing non-working deepsleep code from PRCMU f/w file - cleans redundant code for cpu hotplug - re-orgs the platform pm.c file for supporting uart2/gic/icn/prcc peripheral contexts - fixes FIDO_IR_ER: 258539, make UART2 console as a wakeup event - incorporates review comments from gerrit The "ApSleep" power state can now be entered through the echo standby > /sys/power/state command. FIDO_IR_ER: 258539, add deep sleep support FIDO_IR_ER: 258539, make UART2 console as a wakeup event Signed-off-by: Sundar R Iyer <sundar.iyer@stericsson.com> Acked-By: Biju C Das <biju.das@stericsson.com> Signed-off-by: Mian Yousaf Kaukab <mian.yousaf.kaukab@stericsson.com> Change-Id: I1ebb7fc193ec7dcea765c300277042464868493c Reviewed-on: http://gerrit.lud.stericsson.com/gerrit/2355 Reviewed-by: Jonas ABERG <jonas.aberg@stericsson.com>
