f607e7fc5f w1: ds1wm: add a reset recovery parameter
This fixes a regression in 3.0 reported by Paul Parsons regarding the
removal of the msleep(1) in the ds1wm_reset() function:

: The linux-3.0-rc4 DS1WM 1-wire driver is logging "bus error, retrying"
: error messages on an HP iPAQ hx4700 PDA (XScale-PXA270):
:
: <snip>
: Driver for 1-wire Dallas network protocol.
: DS1WM w1 busmaster driver - (c) 2004 Szabolcs Gyurko
: 1-Wire driver for the DS2760 battery monitor  chip  - (c) 2004-2005, Szabolcs Gyurko
: ds1wm ds1wm: pass: 1 bus error, retrying
: ds1wm ds1wm: pass: 2 bus error, retrying
: ds1wm ds1wm: pass: 3 bus error, retrying
: ds1wm ds1wm: pass: 4 bus error, retrying
: ds1wm ds1wm: pass: 5 bus error, retrying
: ...
:
: The visible result is that the battery charging LED is erratic; sometimes
: it works, mostly it doesn't.
:
: The linux-2.6.39 DS1WM 1-wire driver worked OK.  I haven't tried 3.0-rc1,
: 3.0-rc2, or 3.0-rc3.

This sleep should not be required on normal circuitry provided the
pull-ups on the bus are correctly adapted to the slaves.  Unfortunately,
this is not always the case.  The sleep is restored but as a parameter to
the probe function in the pdata.

8f2df0147f Revert "mfd: Add omap-usbhs runtime PM support"
This reverts commit 7e6502d577.

Oops are produced during initialization of ehci and ohci
drivers. This is because the run time pm apis are used by
the driver but the corresponding hwmod structures and
initialization is not merged. hence revering  back the
commit id 7e6502d577

1ed7891f8d mfd: Use mfd cell platform_data for db8500-prcmu cells platform bits
With the addition of a device platform mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.

a2974732ca TPS65911: Add new irq definitions
TPS65911 adds new interrupt sources, as well as two new registers
to handle them, one for interrupt status and one for interrupt
masking. The added irqs are:

-VMBCH2 - Low and High threshold
-GPIO1-8 - Rising and falling edge detection
-WTCHDG - Watchdog interrupt
-PWRDN	- PWRDN reset interrupt

The code should handle these new registers only when the chip
version is TPS65911.

The TPS65911 is the next generation of the TPS65910 family of
PMIC chips. It adds a few features:

- Watchdog Timer
- PWM & LED generators
- Comparators for system control status

It also adds a set of Interrupts and GPIOs, among other things.

The driver exports a function to identify between different
versions of the tps65910 family, allowing other modules to
identify the capabilities of the current chip.

1f968ff61f mfd: Correct the twl4030-power warning print during script loading
Correcting the if condition check for printing the warning,
if wakeup script is not updated before updating the sleep script.

Since the flag 'order' is set to '1' while updating the wakeup script
for P1P2, the condition checking for printing the warning should be
if(!order) (ie: print the warning if wakeup script is not updated before
updating the sleep script)

a5156f1ade mfd: Fix build warning on 88pm860x
WARNING: vmlinux.o(.devinit.text+0x6c4): Section mismatch in reference
from the function device_onkey_init() to the (unknown reference)
.init.data:(unknown)
The function __devinit device_onkey_init() references a (unknown reference)
 __initdata (unknown).
If (unknown) is only used by device_onkey_init then annotate (unknown)
with a matching annotation.

It's caused by using __initdata on mfd cell resources. Replace __initdata
with __devinitdata.

bc86fcee37 mfd: Continue with IRQ setup even if we don't have PMIC main IRQ
The fact that we can't actually raise any interrupts doesn't stop us
setting up the IRQs we're exporting. While this isn't actually going
to do anything it allows us to proceed further through device setup
during board bringup and avoids issues with the MFD core not letting
us suppress the configuration of IRQ resources.

0b14c22ea1 mfd: Provide platform data for WM831x GPIO configuration
Allow the GPIO mode of WM831x devices to be configured using platform data.
Users may provide a table of GPIO register values in gpio_defaults[]. In
order to allow 0 to be set explicitly out of range values are accepted and
masked off, with a WM831X_GPIO_CONFIGURE define provided to set an out of
range value.

This can be used to configure higher numbered GPIOs or override values set
in OTP for GPIOs configured using OTP.

e45be4b5fc mfd: Use mfd cell platform_data for wm8400 cells platform bits
With the addition of a platform device mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.
