      PM / shmobile: Allow the A4R domain to be turned off at run time · a8cf27be
      由 Rafael J. Wysocki 提交于 
      After adding PM QoS constraints for the I2C controller in the A4R
domain, that domain can be allowed to be turned off and on by runtime
PM, so remove the "always on" governor from it.

However, the A4R domain has to be "on" when suspend_device_irqs() and
resume_device_irqs() are executed during system suspend and resume,
respectively, so that those functions don't crash while accessing the
INTCS.  For this reason, add a PM notifier to the SH7372 PM code and
make it restore power to A4R before system suspend and remove power
from all unused PM domains after system resume.

      PM / shmobile: Remove the stay_on flag from SH7372's PM domains · 767c0f3a
      由 Rafael J. Wysocki 提交于 
      SH7372 uses two independent mechanisms for ensuring that power
domains will never be turned off: the stay_on flag and the "always
on" domain governor.  Moreover, the "always on" governor is only taken
into accout by runtime PM code paths, while the stay_on flag affects
all attempts to turn the given domain off.  Thus setting the stay_on
flag causes the "always on" governor to be unnecessary, which is
quite confusing.

However, the stay_on flag is currently only set for two domains: A3SP
and A4S.  Moreover, it only is set for the A3SP domain if
console_suspend_enabled is set, so stay_on won't be necessary for
that domain any more if console_suspend_enabled is checked directly
in its .suspend() routine.  [This requires domain .suspend() to
return a result, but that is a minor modification.]  Analogously,
stay_on won't be necessary for the A4S domain if it's .suspend()
routine always returns an error code.

      PM / shmobile: Don't include SH7372's INTCS in syscore suspend/resume · 0f966d74
      由 Rafael J. Wysocki 提交于 
      Since the SH7372's INTCS in included into syscore suspend/resume,
which causes the chip to be accessed when PM domains have been
turned off during system suspend, the A4R domain containing the
INTCS has to stay on during system sleep, which is suboptimal
from the power consumption point of view.

For this reason, add a new INTC flag, skip_syscore_suspend, to mark
the INTCS for intc_suspend() and intc_resume(), so that they don't
touch it.  This allows the A4R domain to be turned off during
system suspend and the INTCS state is resrored during system
resume by the A4R's "power on" code.

      PM / shmobile: Add support for the sh7372 A4S power domain / sleep mode · f7dadb37
      由 Magnus Damm 提交于 
      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.

      PM / Domains: Make it possible to use per-device domain callbacks · d5e4cbfe
      由 Rafael J. Wysocki 提交于 
      The current generic PM domains code requires that the same .stop(),
.start() and .active_wakeup() device callback routines be used for
all devices in the given domain, which is inflexible and may not
cover some specific use cases.  For this reason, make it possible to
use device specific .start()/.stop() and .active_wakeup() callback
routines by adding corresponding callback pointers to struct
generic_pm_domain_data.  Add a new helper routine,
pm_genpd_register_callbacks(), that can be used to populate
the new per-device callback pointers.

Modify the shmobile's power domains code to allow drivers to add
their own code to be run during the device stop and start operations
with the help of the new callback pointers.

      This patch updates the Kota2 board support code to
use the recently merged TPU LED driver whenever
possible.

The sh73a0 SoC has 5 TPU hardware blocks each with
4 timer channels which in theory allows a total of
20 LEDs to be controlled by "leds-renesas-tpu"
driver instances. The Kota2 board has 4 LEDs connected
to GPIO pins that also come with TPU pin functions, so
this patch ties up these 4 LEDS and leaves the remaining
3 LEDS for the GPIO based LED driver.
