A bunch of fixes for regressions (and a few other problems) in 3.4-rc1:
* Fix for regression of mach/io.h cleanup on platforms with PCI or PCMCIA
(adding back the include file on those for now)
* AT91 fixes for usb and spi
* smsc911x ethernet fixes for i.MX
* smsc911x fixes for OMAP
* gpio fixes for Tegra
* A handful of build error and warning fixes for various platforms
* cpufreq kconfig dependencies, build and lowlevel debug fixes for
Samsung platforms
In other words, more or less the regular collection of -rc1/2 type
material. A few of them, in particular the smsc911x for OMAP series, aren't
technically regressions for 3.4, but they're valid fixes and we're still
relatively early in the rc cycle so it seems appropriate to include them.

I still need to send a few checkpoint/restore patches. I've been
wobbly about merging them because I'm wobbly about the overall

Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op. This leads to a
proliferation of the default_open() implementation across the entire
tree.
Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().
This replacement was done with the following semantic patch:

With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was
broken. PCMCIA depends on __io() returning a valid i/o address, and most
ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This
needs a better fix with a fixed i/o address mapping, but for now we just
restore things to the previous behavior.
This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled,
but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff,
so it doesn't need an io.h.

Note that this also contains a set of fixes that are not regressions
or oopses to properly deal with the smsc911x regulator issue.
Basically the regulators must be per board file as the regulators
can also come from drivers, such as twl4030. So it's best to dumb
down gpmc-smsc911x.c to not even care about the regulators.

Commit b1cbdb00d ("OMAP: clockdomain: Wait for powerdomain to be ON
when using clockdomain force wakeup") was assuming that
pwrdm_state_switch() does wait for the powerdomain transition which is
not the case. The missing wait for the powerdomain transition
violates the sequence which the hardware expects, which causes power
management failures on some devices.
Fix this API by adding the pwrdm_wait_transition().

Fixing it to read from the physical or virtual address depending

between head.S and exynos_map_io where the mmu is on, the uart
is mapped and used, but the chipid mapping is not yet present.

clk_disable_unused is invoked when CONFIG_OMAP_RESET_CLOCKS=y.
Since clk_disable_unused is called as lateinitcall, there can
be more than a few workqueues executing off secondary CPU(s).
The current code does the following:
a) checks if clk is unused
b) holds lock
c) disables clk
d) unlocks
Between (a) and (b) being executed on CPU0, It is possible to
have a driver executing on CPU1 which could do a get_sync->clk_get
(and increase the use_count) of the clock which was just about
to be disabled by clk_disable_unused.
We ensure instead that the entire list traversal is protected by
the lock allowing for parent child clock traversal which could be
potentially be done by runtime operations to be safe as well.

If transceiver is attached to a MMC host of ES2.1 OMAP35xx, it seems
2.1.1.128 erratum doesn't apply and there is no data corruption,
probably because of different signal timing. The workaround for this
erratum disables multiblock reads, which causes dramatic loss of
performance (over 75% slower), so avoid it when transceiver is present.

Fix the below section mismatch warning and alike:
WARNING: vmlinux.o(.text+0x281d4): Section mismatch in reference from
the function setup_ehci_io_mux() to the function
.init.text:omap_mux_init_signal()
The function setup_ehci_io_mux() references
the function __init omap_mux_init_signal().
This is often because setup_ehci_io_mux lacks a __init
annotation or the annotation of omap_mux_init_signal is wrong.

With CONFIG_OMAP4_ERRATA_I688 enabled, omap2+ build

arch/arm/kernel/io.c:29: error: implicit declaration of function 'outer_sync'
make[1]: *** [arch/arm/kernel/io.o] Error 1

Initialize fixed regulators in the board files. Trying to
do this in a generic way in gpmc-smsc911x.c gets messy as
the regulator may be provided by drivers, such as twl4030,
for some boards.

Adding in support for regulators here creates several headaches.
- Boards that declare their own regulator cannot use this function.
- Multiple calls to this function require special handling.
- Boards that declare id's other than '0' need special handling.
Now that there is a simple regulator_register_fixed, we can push
this registration back into the board files.

Looking back into git history, this code was never used and was
probably left over from a copy/paste.

If this function is called the first time with flags set, and the
second time without flags set then the leftover flags from the first
called will be used rather than the desired default flags.

This seems to be a leftover from when gpmc-smsc911x.c was copied

Commit 086ada54ab
"FB: sa1100: remove global sa1100fb_.*_power function pointers"
got rid of all instances but one in locomolcd.c -- which was
conditional on CONFIG_SA1100_COLLIE. The associated .power
field which replaces the global is populated in mach-sa1100/collie.c
so move the assignment there, but make it conditional on the
locomolcd support, so use CONFIG_BACKLIGHT_LOCOMO in that file.

commit 9f786d033d
"arm/PCI: get rid of device resource fixups"
causes this failure on the versatile:
arch/arm/mach-versatile/pci.c: In function 'pci_versatile_setup_resources':
arch/arm/mach-versatile/pci.c:221: error: 'sys' undeclared (first use in this function)
because the versatile wasn't passing in the full struct pci_sys_data
but only the resource sub-field. Change it to pass in the full
struct so that sys will be in scope.

This merges some of the fixes from Paul Gortmaker for the header file
cleanup fallout.
Some of the patches are going through arch maintainer trees, and David
Howells suggested another be done differently, but this at least fixes a
few cases.
