This patch reverts "ARM: mach-shmobile: sh7372 SDHI vector merge" and
supplies 3 IRQ resources for each SDHI block.
Some blocks have a 4th IRQ, but this is used for DRM feathres
that I do not have access tot he documentation for and are almost
certainly tainted by licensing issues. So the 4th IRQ is not
hooked-up even if it exists.

Update the sh7372 clock code to set the RT side
set of MSTP bits to a fixed disabled state.
The sh7372 SoC contains two sets of MSTP bits,
one for the ARM (SYS) side, and one for the
SH4AL-DSP (RT) side. The actual clock associated
with the MSTP bit will only be stopped when both
sides have set the MSTP bit to disabled mode.
Some MSTP bits are enabled by default after
hardware reset, so this patch adjusts the code
to disable all MSTP bits associated with the RT
side to allow the SYS side to have full control.

Many different platforms and subsystems may want to disable device
clocks during suspend and enable them during resume which is going to
be done in a very similar way in all those cases. For this reason,
provide generic routines for the manipulation of device clocks during

Some subsystems need to attach PM-related data to struct device and
they need to use devres for this purpose. For their convenience
and to make code more straightforward, add a new field called
subsys_data to struct dev_pm_info and let subsystems use it for
attaching PM-related information to devices.
Convert the ARM shmobile platform to using the new field.
Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
shmobile platforms replace the runtime PM callbacks of the platform
bus type with their own routines, but this means that the callbacks
are replaced system-wide. This may not be the right approach if the
platform devices on the system are not of the same type (e.g. some
of them belong to an SoC and the others are located in separate
chips), because in those cases they may require different handling.
Thus it is better to use power domains to override the platform bus
type's PM handling, as it generally is possible to use different
power domains for devices with different PM requirements.
Define a default power domain for shmobile in both the SH and ARM
falvors and use it to override the platform bus type's PM callbacks.
Since the suspend and hibernate callbacks of the new "default" power
domains need to be the same and the platform bus type's suspend and
hibernate callbacks for the time being, export those callbacks so
that can be used outside of the platform bus type code.

Current format selection of FSI-codecs depended on platform information for FSI,

This patch modify FSI and FSI-codecs to use snd_soc_dai_set_fmt.
But FSI can use I2S/PCM and SPDIF format today.
It can be selected to I2S/PCM by snd_soc_dai_set_fmt, but can not select SPDIF.
So, this patch change FSI platform information to have DAI/SPDIF mode.
If platform selects DAI mode (default),
FSI-codecs can select I2S/PCM by snd_soc_dai_set_fmt,
and if it is SPDIF mode, FSI become SPDIF format.

This allows a ROM-able zImage to be written to MMC and
for SuperH Mobile ARM to boot directly from the MMCIF
hardware block.
This is achieved by the MaskROM loading the first portion
of the image into MERAM and then jumping to it. This portion
contains loader code which copies the entire image to SDRAM
and jumps to it. From there the zImage boot code proceeds
as normal, uncompressing the image into its final location
and then jumping to it.

* Initialise LED GPIO lines in head-ap4evb.txt instead of mmcif-sh7372.c

* Move mmcif_loader to be earlier in the image and

* Move LED GPIO initialisation into mmcif_progress_init

Fix interrupt priority level handling on SH-Mobile ARM.
SH-Mobile ARM platforms using multiple interrupt priority
levels need this patch to fix a potential dead lock that
may occur if multiple interrupts with different levels
are pending simultaneously.
The default INTC configuration is to use the same priority
level for all interrupts, so this issue does not trigger by
default. It is however common for board code to override the
interrupt priority for certain interrupt sources depending
on the application. Without this fix such boards may lock up.
In detail, this patch updates the INTC code in entry-macro.S
to make sure that the INTLVLA register gets set as expected.
To trigger this bug modify the board specific code to adjust
the interrupt priority level for the ethernet chip. After
changing the priority level simply use flood ping to drown
the board with interrupts.
This patch applies to INTCA-based processors such as sh7372,
sh7377 and sh7372. GIC-based processors are not affected.
Suitable for v2.6.37-rc and stable from v2.6.34 to v2.6.36.

Presently each one of the CPUs manually selects the same feature set, and
there's a reasonable expectation that none of these will change for
future CPUs in the SH-Mobile / R-Mobile family, so we move those over to
the top-level ARCH_SHMOBILE.
While we're at it, all of the CPUs support optional GPIOs via the PFC,
do not have I/O ports, and expect sparse IRQ, so we bring the
configuration in line across the board.
This more or less brings the ARM-based parts in sync with their SH

On AP4EVB the card detect pin of the top SD/MMC slot is not directly
connected to the tmio/mmcif controller but to a GPIO pin, so polling
needs to be done for SDHI1 and MMCIF in order to support hotplug for
that slot. SHDI1 and MMCIF share that slot, and the used controller
is selected by a DIP switch.
This patch adds a helper function to check if a card is present in that
particular slot, registers this function with SDHI1 and MMCIF and enables
polling for SDHI1.
