b330f85d3d mfd: Add missing hunk to change palmas irq to clear on read
During conversion to regmap_irq this hunk was missing being moved
to MFD driver to put the chip into clear on read mode. Also as slave
is now set use it to determine which slave for the register call.

adc20e02ae mfd: Fix palmas regulator pdata missing
Due to a merge error the section of code passing the pdata for the
regulator driver to the mfd_add_devices via the children structure
was missing. This corrects this problem.

c05995c3d7 mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix issues.
'ARM: OMAP3: USB: Fix the EHCI ULPI PHY reset issue' (1fcb57d0) fixes
an issue where the ULPI PHYs were not held in reset while initializing
the EHCI controller. However, it also changes behavior in
omap-usb-host.c omap_usbhs_init by releasing reset while the
configuration in that function was done.

This change caused a regression on BB-xM where USB would not function
if 'usb start' had been run from u-boot before booting. A change was
made to release reset a little bit earlier which fixed the issue on
BB-xM and did not cause any regressions on 3430 sdp, the board for
which the fix was originally made.

This new fix, 'USB: EHCI: OMAP: Finish ehci omap phy reset cycle
before adding hcd.', (3aa2ae74) caused a regression on OMAP5.

The original fix to hold the EHCI controller in reset during
initialization was correct, however it appears that changing
omap_usbhs_init to not hold the PHYs in reset during it's
configuration was incorrect. This patch first reverts both fixes, and
then changes ehci_hcd_omap_probe in ehci-omap.c to hold the PHYs in
reset as the original patch had done. It also is sure to incorporate
the _cansleep change that has been made in the meantime.

I've tested this on Beagleboard xM, I'd really like to get an ack from
the 3430 sdp and OMAP5 guys before getting this merged.

v3 - Brown paper bag its too early in the morning actually run
     git commit amend fix
v2 - Put cansleep gpiolib call outside of spinlock

ada72d0a93 mfd: mc13xxx workaround SPI hardware bug on i.Mx
The MC13xxx PMIC is mainly used on i.Mx SoC. On those SoC the SPI
hardware will deassert CS line as soon as the SPI FIFO is empty.
The MC13xxx hardware is very sensitive to CS line change as it
corrupts the transfer if CS is deasserted in the middle of a register
read or write.
It is not possible to use the CS line as a GPIO on some SoC, so we
need to workaround this by implementing a single SPI transfer to
access the PMIC.

2e341ca686 Sound updates for 3.5-rc1
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.

include/linux/mfd/db8500-prcmu.h:685:20: note: previous definition of 'prcmu_ac_sleep_req' was here

Problem:
When CONFIG_AB8500_CORE is set, building ab8500-core.c and
!(CONFIG_UX500_SOC_DB8500 | CONFIG_MFD_DB8500_PRCMU), both db8500-prcmu.h
and dbx500-prcmu.h take it upon themselves to _both_ create 'return 0'
inline functions for the following:

prcmu_abb_read()
prcmu_abb_write()
prcmu_config_clkout()
prcmu_ac_wake_req()
prcmu_ac_sleep_req()

Solution:
Depend on MFD_DB8500_PRCMU, which in turn depends on UX500_SOC_DB8500.

9bc747bea5 arm-soc: First batch of cleanups
These cleanups are basically all over the place. The idea is to collect
 changes with minimal impact but large number of changes so we can avoid
 them from distracting in the diffstat in the other series.
 
 A significant number of lines get removed here, in particular because
 the ixp2000 and ixp23xx platforms get removed. These have never been
 extremely popular and have fallen into disuse over time with no active
 maintainer taking care of them. The u5500 soc never made it into a
 product, so we are removing it from the ux500 platform.
 
 Many good cleanups also went into the at91 and omap platforms, as has
 been the case for a number of releases.

 - Helpers in the core for regulators using regmap, providing generic
   implementations of the enable and voltage selection operations which
   just need data to describe them in the drivers.
 - Split out voltage mapping and voltage setting, allowing many more
   drivers to take advantage of the infrastructure for selectors.
 - Loads and loads of cleanups from Axel Lin once again, including many
   changes to take advantage of the above new framework features
 - New drivers for Ricoh RC5T583, TI TPS62362, TI TPS62363, TI TPS65913,
   TI TWL6035 and TI TWL6037.
 
 Some of the registration changes to support the core refactoring caused
 so many conflicts that eventually topic branches were abandoned for this
 release.

cd99758ba3 mfd: Convert wm831x to irq_domain
The modern idiom is to use irq_domain to allocate interrupts. This is
useful partly to allow further infrastructure to be based on the domains
and partly because it makes it much easier to allocate virtual interrupts
to devices as we don't need to allocate a contiguous range of interrupt
numbers.

Convert the wm831x driver over to this infrastructure, using a legacy
IRQ mapping if an irq_base is specified in platform data and otherwise
using a linear mapping, always registering the interrupts even if they
won't ever be used. Only boards which need to use the GPIOs as
interrupts should need to use an irq_base.

This means that we can't use the MFD irq_base management since the
unless we're using an explicit irq_base from platform data we can't rely
on a linear mapping of interrupts.  Instead we need to map things via
the irq_domain - provide a conveniencem function wm831x_irq() to save a
small amount of typing when doing so. Looking at this I couldn't clearly
see anything the MFD core could do to make this nicer.

Since we're not supporting device tree yet there's no meaningful
advantage if we don't do this conversion in one, the fact that the
interrupt resources are used for repeated IP blocks makes accessor
functions for the irq_domain more trouble to do than they're worth.
