ARM: mach-shmobile: sh7372 A3SM support
This patch adds sh7372 A3SM power domain support. The sh7372 A3SM hardware power domain contains the ARM Cortex-A8 CPU Core including L2 cache. This sleep mode can be seen as a one step deeper sleep mode from the already existing Core Standby mode. To wake up from A3SM sleep only a few wakeup sources are supported - so the regular INTC controller will not be able to help us unfortunately. The code in this patch will enter A3SM sleep via the regular Suspend-to-RAM interface in the case of only wakeups supported by A3SM are enabled. If unsupported wakeups are enabled then Core Standby will be used instead. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
