'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which the fix was originally made.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.

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.

As the AB8500 is a subordinate MFD device to the DB8500-PRCMU,
for consistency and a better 1:1 depiction of how the hardware
is laid out, it is a good idea to register it in the same way
as we do for the other MFD child devices. In order for us to do
this successfully we have to pass AB8500's platform data when
registering the DB8500-PRCMU from platform code.
Also solves this issue:

the internal RC oscillator is used at power-on, but the external crystal

During Device Tree enablement of the ab8500 and db8500-prcmu drivers,
a decision was made to omit registration through the MFD API and use
Device Tree directly. However, because MFD devices have a different
address space and the ab8500 and db8500 both use I2C to communicate,
this causes issues with address translation during execution of
of_platform_populate(). So the solution is to make the MFD core aware
of Device Tree and have it assign the correct node pointers instead.
To make this work the MFD core also needs to be awere of IRQ domains,
as Device Tree insists on IRQ domain compatibility. So, instead of
providing an irq-base via platform code, in the DT case we simply
look up the IRQ domain and map to the correct virtual IRQ.

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.

This patch is device driver for MAX77686 chip.
MAX77686 is PMIC and includes regulator and rtc on it.
This driver is core of MAX77686 chip, so provides common support for
accessing on-chip devices. It uses irq_domain to manage irq and regmap
to read/write data to its register with i2c bus.

Several forthcoming Wolfson devices are based on a common platform
known as Arizona allowing a great deal of reuse of driver code. This
patch adds support for the interrupt controller on Arizona class devices.
Since there are two interrupt domains in the device which share a single
/IRQ pin by default we use two regmap IRQ domains with a trivial demux
interrupt domain used to distribute the interrupts to the two devices.
The devices do support multiple interrupt signals, future work will enable
support for using this feature to avoid the demux.

Several forthcoming Wolfson devices are based on a common platform
known as Arizona allowing a great deal of reuse of driver code. This
patch adds core support for these devices.
In order to handle systems which do not use the generic clock API a
simple wrapper for the 32kHz clock domain in the devices is provided.
Once the generic clock API is widely available this code will be moved
over to use that.
For simplicity some WM5102 specific code is included in the core driver,
the effort involved in splitting the device out isn't worth it.

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.

maintainer taking care of them. The u5500 soc never made it into a

Many good cleanups also went into the at91 and omap platforms, as has
been the case for a number of releases.

Pull first batch of arm-soc cleanups from Olof Johansson:
"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

The major thing here is the addition of some helpers to factor code out
of drivers, making a fair proportion of regulators much more just data
rather than code which is nice.
- 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.

Since commit 587a1f1659 ("switch ->is_visible() to returning umode_t")
the return type of is_visible is umode_t rather than mode_t.
This silences a compiler warning on some architectures where these types

Device tree based probing support for the core twl6040 driver. Child
devices will be created as MFD devices:
- ASoC codec is always created
- Vibra child is only created if the vibra section present in the DT blob.

The main function of the twl6040 is to provide audio on OMAP4+ platforms.
Since the ASoC codec driver can work without the pdata we can register the
child to load the codec driver whenever the twl6040 MFD driver is loaded.

Use irq_alloc_descs() to get the IRQ number range dynamically instead of
the hardwired use if pdata->irq_base.
The twl6040 only provides interrupts for it's internal components which
means that it is not working as an IRQ expander type of device.
The client drivers will receive their interrupt numbers as resource which
is configured based on the received IRQ range we got from irq_alloc_descs()

ab8500-i2c is used as core code to register the ab8500 device.
After allocating ab8500 memory, it immediately calls into
ab8500-core where the real initialisation takes place. This

the true ab8500-core file and removes ab8500-i2c completely.
