This patch contains r8a7779 SMP support V3 - now including
CPU hotplug offine and online support. The r8a7779 power
domain code is tied together with SMP glue code which allows
us to control the power domains via CPU hotplug.
At this point the kernel boots with the 4 Cortex-A9 cores in
SMP mode and all CPU cores except CPU0 can be hotplugged.
The code in platsmp.c is quite far from pretty, but it is
kept like that intentionally to avoid creating layers of
code that will go away in the near future anyway. The code
needs to be updated when some per-SoC handling code will be
added to the ARM architecture, see the following patch for
more information:

Add power domain control support for the r8a7779 SoC V2.
This adds support for 4 power domains for I/O Devices
together with code that can be used for CPU cores as well.
The only out of the ordinary experience is the need for
ioremap() of SYSC registers. Because of that we need to
execute some init function before setting up the domains.

Add cache flushing code to the SH-Mobile specific CPU hotplug
implementation. While at it, add a cpu mask to make sure the
cache flushing code is finished in platform_cpu_die() before
letting the SoC-specific code in shmobile_platform_cpu_kill()
proceed with turning off power.
Without this code CPU hotplug offline fails when cache is
enabled on Cortex-A9 based SoCs.

Convert the low level SMP assembly code for SH-Mobile ARM

onlining of CPUs using the CPU hotplug interface:

will be freed as init section data and CPU cores cannot

Initial support for the r8a7779 SoC and the Marzen board (V2).
Only SCIF ports and the TMU are supported at this point.
To keep things simple only entity-mapped virt-to-phys mappings
are supported. This forces drivers and other SoC glue code to
make use of ioremap(). We cannot support early serial console
due to virtual address space collisions with the ARM kernel.

resolution multimedia workloads using the same
legacy memory allocating solution as on SH.
There are no in-tree kernel dependencies on the
158MiB setting, and future development should
reserve and allocate memory using some other
method like for instance CMA.

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.

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.

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.

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.

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.
