This patch adds SMSC ethernet support on Bock-W
Bock-W SMSC needs FPGA settings which enables interrupt.
This patch does it on bockw_init() function.
As notes for future, this FPGA settings should be updated,
since this FPGA is using cascaded interrupt.
Current code is assuming that this FPGA interrupt user is only SMSC.

With the added capabilty of the intc_irqpin driver to handle shared
external IRQs, all prerequisites are fulfilled and we are ready to
migrate completely to GIC. This includes the following steps:
- Kconfig: select ARM_GIC and RENESAS_INTC_IRQPIN
- intc-r8a7740: Throw out all legacy INTC code and init the GIC. We need
to mask out all shared IRQs as it is needed by the
shared intc_irqpin driver.
- setup-r8a7740: Add 4 irqpin devices to handle external IRQs and update
all IRQ numbers to point to the GIC SPI.
- board-armadillo: Update all IRQ numbers to point to the GIC SPI.
- pfc-r8a7740: Update all IRQ numbers of the GPIOs to point to the GIC

Provide alternate board code for the kzm9g to demonstrate
how DT may be used given the current state of driver
device tree support. This is intended to act as a reference
for mach-shmobile developers.
Some notes:
* Brings up the GIC interrupt handler using device tree
* Brings up the following device using device tree:
- MMCIF (MMC)
* Does not bring up the INTC interrupt controller at all,
thus external devices may not be used. In particular,
the SMSC ethernet device may not be used and thus
NFS root may not be used.
* Uses existing C code and not device tree to initialise the following,
which are needed for a working board:
- SCIF (Serial)
- CMT (Clock)
- PFC (GPIO)
To use this alternate board code instead of the normal board code,
CONFIG_MACH_KZM9G_REFERENCE should be selected in the kernel config.
And the sh73a0-kzm9g-reference.dtb flattened device tree blob should be used.
Includes fix by Thierry Reding to no longer use gic_handle_irq()

Update the r8a7779 IRQ code to make use of the
INTC External IRQ pin driver for external
interrupt pins IRQ0 -> IRQ3.
The r8a7779 SoC can like older SH SoCs configure
to use the IRQ0 -> IRQ3 signals as individual
interrupts or a combined IRL mode.
Without this patch the r8a7779 SoC code does
not fully support external IRQ pins in individual
IRQ mode. The r8a7779 PFC code does not yet have
gpio_to_irq() support so no need to update such
code.
At this point the DT reference implementations
are not covered. In the future such code shall
tie in the INTC External IRQ pin driver via
DT, so this kind of verbose code is not needed
for the long term DT case.

Adjust the sh73a0 IRQ code to make use of the

This removes quite a bit of special-case code
in intc-sh73a0.c but the number of lines get
replaced with platform device information in
setup-sh73a0.c. The PFC code is also adjusted
to make gpio_to_irq() return the correct
interrupt number.
At this point the DT reference implementations

As suggested by Andrew Morton:
This is a pet peeve of mine. Any time there's a long list of items
(header file inclusions, kconfig entries, array initalisers, etc) and
someone wants to add a new item, they *always* go and stick it at the
end of the list.
Guys, don't do this. Either put the new item into a randomly-chosen
position or, probably better, alphanumerically sort the list.
lets sort all our select statements alphanumerically. This commit was
created by the following perl:
while (<>) {
while (/\\\s*$/) {
$_ .= <>;
}
undef %selects if /^\s*config\s+/;
if (/^\s+select\s+(\w+).*/) {
if (defined($selects{$1})) {
if ($selects{$1} eq $_) {
print STDERR "Warning: removing duplicated $1 entry\n";
} else {
print STDERR "Error: $1 differently selected\n".
"\tOld: $selects{$1}\n".
"\tNew: $_\n";
exit 1;
}
}
$selects{$1} = $_;
next;
}
if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
/^endif/ or /^endchoice/)) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
undef %selects;
}
print;
}
if (%selects) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
}
It found two duplicates:
Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry
and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.

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
forcing REGULATOR_FIXED_VOLTAGE on if REGULATOR is selected.

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.

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.

Tie in the Emma Mobile GPIO driver "em-gio" to

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.

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

R8A7740 GIC can not get external IRQx interrupt directly
without GIC - INTC demux support.
Current AG5 is using GIC - INTCS demux with
special irq relocation. but GIC - INTCA demux
is still not supported and it needs irq number re-mapping.
OTOH, normal INTC support as before is very enough for R8A7740,
because it is not SMP CPU.
This patch adds INTCA/INTCS support instead of GIC.

This patch adds initial support for Renesas SH-Mobile AG5.
At this point the AG5 CPU support is limited to the ARM
core, SCIF serial and a CMT timer together with L2 cache
and the GIC. The AG5EVM board also supports Ethernet.
Future patches will add support for GPIO, INTCS, CPGA
and platform data / driver updates for devices such as
IIC, LCDC, FSI, KEYSC, CEU and SDHI among others.
The code in entry-macro.S will be cleaned up when the
ARM IRQ demux code improvements have been merged.
Depends on the AG5EVM mach-type recently registered but
not yet present in arch/arm/tools/mach-types.
As the AG5EVM board comes with 512MiB memory it is
recommended to turn on HIGHMEM.
Many thanks to Yoshii-san for initial bring up.

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
counterparts.

Many of the config bit are presently duplicated between the platforms,
