2011-12-25	PM / shmobile: Add support for the sh7372 A4S power domain / sleep mode	Magnus Damm	1	-10/+11
	The sh7372 contains a power domain named A4S which in turn contains power domains for both I/O Devices and CPU cores. At this point only System wide Suspend-to-RAM is supported, but the the hardware can also support CPUIdle. With more efforts in the future CPUIdle can work with bot A4S and A3SM. Tested on the sh7372 Mackerel board. [rjw: Rebased on top of the current linux-pm tree.] Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2011-09-25	ARM: mach-shmobile: sh7372 sleep warning fixes	Magnus Damm	1	-0/+2
	Update the sh7372 sleep code to build parts of the code only when SUSPEND and/or CPU_IDLE are set. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2011-09-25	ARM: mach-shmobile: sh7372 A3SM support	Magnus Damm	1	-2/+53
	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>
2011-09-25	ARM: mach-shmobile: sh7372 generic suspend/resume support	Magnus Damm	1	-224/+6
	Convert the sh7372 Core Standby code to make use of the new generic ARM cpu suspend/resume code. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2011-05-25	ARM: mach-shmobile: sh7372 Core Standby Suspend-to-RAM	Magnus Damm	1	-0/+260
	Add sh7372 Core Standby sleep mode support and tie it in with the shared SH-Mobile ARM suspend code. The Core Standby mode is the lightest sh7372-specific sleep mode, cutting power to the ARM core excluding the L2 cache. Any interrupt source can be used for wakeups. The low level portion of this code is based on the TI OMAP sleep code in sleep34xx.S, thanks to them. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
