Add a "C5" cpuidle state to the SH7372 SoC connected to the A4S power
domain in such a way that A4S may be turned off by cpuidle if all
I/O devices in that domain have been suspended (or do not have
attached drivers).
This requires some reorganization of the initialization of SH7372
power management which affects the the boards based on it, Mackerel
and AP4EVB.

The sh7372 cpuidle code uses the same artificially designed routine
shmobile_cpuidle_enter() as the .enter() callback for all of its
cpuidle states. However, shmobile_cpuidle_enter() calls a different
"enter" function for each state using an array of function pointers
populated by the sh7372 PM initialization code. Moreover, the
states[] array of the shmobile cpuidle driver is populated by that
code as well, although in principle it just might have been filled
with static data.
All of that complexity goes away if the sh7372 cpuidle code is
allowed to define its own cpuidle driver structure that can be passed
for registration to the common shmobile cpuidle initialization
routine, so modify the code accordingly.

The role of the only function in the common.c file in
arch/arm/mach-shmobile, shmobile_init_late(), is to call two
initializers whose definitions depend on kernel configuration
options. Those initializers may very well be called from a static
inline function in arm/mach-shmobile/include/mach/common.h,
though, in which makes the code a bit easier to read. Moreover,
the common.c may be dropped entirely then.

The sh7372_enter_suspend() routine checks the status field of the

However, it shouldn't rely on the specific values of the generic

recognize when it is safe to turn that domain off.
For this purpos, introduce a boolean variable a4s_suspend_ready

If the r8a7779's PM domains are given names, this SoC and its boards
will be able to use rmobile_add_device_to_domain() for adding devices
to those domains and r8a7779_add_device_to_domain(), which is not
used anywhere at the moment anyway, may be dopped.
Accordingly, give names to the r8a7779's PM domains and drop
r8a7779_add_device_to_domain().

renesas_usbhs driver can play role as both Host and Gadget.
In case of Gadget, it requires not only renesas_usbhs
but also usb gadget module (like g_ether).
So, renesas_usbhs driver calls usb_add_gadget_udc() on probe time.
Because of this behavior,
Host port plays also Gadget role if kernel has both Host/Gadget support.
In mackerel case, from 0ada2da518
(ARM: mach-shmobile: mackerel: use renesas_usbhs instead of r8a66597_hcd)
usb0 plays Gadget role, and usb1 plays Host role,
and current mackerel board probes as usb1 -> usb0.
Thus, 1st installed usb gadget module (like g_ether) will be
assigned to usb1 (= usb Host port), and 2nd module to usb0 (= usb Gadget port).
It is very confusable for user.
This patch fixup usb modes probing order as usb0 -> usb1.

it was purposely registered in reverse order.

sh73a0 :: intca_irq_pins_desc irq table had conflict
from irq 552 to irq 557 before.

But now, we have irqdomain support from

On systems, using regulators to supply power to devices, if the REGULATOR
Kconfig option is disabled, regulator API stubs will be used, which often
suffices to bring a default configuration up. If REGULATOR is enabled but
respective regulator drivers are inactive, the real regulator API calls
will be used, which in the absence of drivers will fail to provide
services. This patch prevents such a problem on sh-mobile boards by

This is a patch series from Shawn Guo that moves from individual
late_initcalls() to using a member in the machine structure to invoke
a platform's late initcalls.
This cleanup is a step in the move towards multiplatform kernels since
it would reduce the need to check for compatible platforms in each and
every initcall.

This is the first big chunk for 3.5 merges of sound stuff.
There are a few big changes in different areas. First off, the
streaming logic of USB-audio endpoints has been largely rewritten
for the better support of "implicit feedback". If anything about USB
got broken, this change has to be checked.
For HD-audio, the resume procedure was changed; instead of delaying
the resume of the hardware until the first use, now waking up immediately
at resume. This is for buggy BIOS.
For ASoC, dynamic PCM support and the improved support for digital links
between off-SoC devices are major framework changes.
Some highlights are below:
* HD-audio
- Avoid the accesses of invalid pin-control bits that may stall the codec
- V-ref setup cleanups
- Fix the races in power-saving code
- Fix the races in codec cache hashes and connection lists
- Split some common codes for BIOS auto-parser to hda_auto_parser.c
- Changed the PM resume code to wake up immediately for buggy BIOS
- Creative SoundCore3D support
- Add Conexant CX20751/2/3/4 codec support
* ASoC
- Dynamic PCM support, allowing support for SoCs with internal routing
through components with tight sequencing and formatting constraints
within their internal paths or where there are multiple components
connected with CPU managed DMA controllers inside the SoC.
- Greatly improved support for direct digital links between off-SoC
devices, providing a much simpler way of connecting things like digital
basebands to CODECs.
- Much more fine grained and robust locking, cleaning up some of the
confusion that crept in with multi-component.
- CPU support for nVidia Tegra 30 I2S and audio hub controllers and
ST-Ericsson MSP I2S controolers
- New CODEC drivers for Cirrus CS42L52, LAPIS Semiconductor ML26124, Texas
Instruments LM49453.
- Some regmap changes needed by the Tegra I2S driver.
- mc13783 audio support.
* Misc
- Rewrite with module_pci_driver()
- Xonar DGX support for snd-oxygen
- Improvement of packet handling in snd-firewire driver
- New USB-endpoint streaming logic
- Enhanced M-audio FTU quirks and relevant cleanups
- Increment the support of OSS devices to 256
- snd-aloop accuracy improvement
There are a few more pending changes for 3.5, but they will be
sent slightly later as partly depending on the changes of DRM.

While we generally attempt to get rid of board specific files and replace
them with device tree based descriptions, a lot of platforms have not
come that far:
In shmobile, we add two new board files because their recently started
effort to add DT support has not proceeded enough to use it for all of
the important hardware.
In Kirkwood, we are adding support for new boards with a combination of
DT and board file contents in multiple cases.
pxa/mmp and imx are extending support for existing board files but not
adding new ones.

This is EMEV2 DT support V3. The support is limited to

handled by "em-sti". Clocks and SMP are not supported.

Tie in the Emma Mobile GPIO driver "em-gio" to
support the GPIOs on Emma Mobile EV2.
A static IRQ range is used to allow boards to
hook up their platform devices to the GPIOs.
DT support is still on the TODO for the GPIO driver,
so only platform device support is included here.

This is V3 of Emma Mobile EV2 SMP support.
At this point only the most basic form of SMP operation
is supported. TWD and CPU Hotplug support is excluded.
Tied to both the Emma Mobile EV2 and the KZM9D board
due to the need to switch on board in platsmp.c and
the newly introduced need for static mappings.
The static mappings are needed to allow hardware
acces early during boot when SMP is initialized.
This early requirement forces us to also map in
the SMU registers.
