When trying to get rid of the cross-includes of <mach/id.h>
from different drivers, so we can localize ASIC/CPU detection
to the mach-ux500 folder, we run into the way the PRCMU
handles base addresses and firmware detection.
This patch updates the firmware version detection to pass
the required information as platform data instead of
relying on cpu_is_* macros.
Now the PRCMU base address, the secondary TCDM area, the
TCPM area and the IRQ are passed as resources instead of
being grabbed from <mach/*> files. Incidentally this also
removes part of the reliance on <mach/irqs.h>.
Further it updates the firmware version detection, since the
location of the firmware ID bytes in the designated memory
are is now passed from the platform data instead. There is
no reason not to include the nice split-off of a struct to
hold the firmware information and a separate function to
populate it.
The patch actually rids the need to use the external
db8500_prcmu_early_init call at all, but I'm keepin back
that removal as I don't want the patch to be too big.

AB8500 GPIO no longer handles its GPIO IRQs. Instead, the AB8500
core driver has taken back the responsibility. Prior to this
happening, the AB8500 GPIO driver provided a set of virtual IRQs
which were used as a pass-through. These virtual IRQs had a base
of MOP500_AB8500_VIR_GPIO_IRQ_BASE, which was passed though pdata.
We don't need to do this anymore, so we're pulling out the
property from the structure.

Today the battery recharge is determined with a voltage threshold. This
voltage threshold is only valid when the battery is relaxed. In charging
algorithm the voltage read is the loaded battery voltage and no
compensation is done to get the relaxed voltage. When maintenance
charging is not selected, this makes the recharging condition to almost
immediately activate when there is a discharge present on the battery.
Depending on which vendor the battery comes from this behavior can wear
out the battery much faster than normal.
The fuelgauge driver is responsible to monitor the actual battery
capacity and is able to estimate the remaining capacity. It is better to
use the remaining capacity as a limit to determine when battery should
be recharged.

Note, some MFD drivers got added through this tree, and they are also

Here's the large driver core updates for 3.8-rc1.
The biggest thing here is the various __dev* marking removals. This is
going to be a pain for the merge with different subsystem trees, I know,
but all of the patches included here have been ACKed by their various
subsystem maintainers, as they wanted them to go through here.
If this is too much of a pain, I can pull all of them out of this tree
and just send you one with the other fixes/updates and then, after
3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
it's up to you. The merges should all be trivial, and Stephen has been
doing them all in linux-next for a few weeks now quite easily.
Other than the __dev* marking removals, there's nothing major here, some

Currently the AB8500 battery management subsystem receives platform
specific information via two different means depending on how the
platform is booted. If DT is not enabled, a reference to a *_bm_data
data structure containing each platform specific attribute is passed
though platform_data. However, if DT is enabled, then platform_data
is empty and the reference is gained though a DT specific probe
function. There are two issues here 1) the same reference is
being collected each time and 2) the DT way doesn't allow any
provisions to select different platform specific attributes, which
kind of defeats the object.

The platform specific battery management configuration data structure
is currently called 'bat' short for 'battery'; however, it contains
information for all components of the battery management group, rather
than information pertaining to the battery itself - there are other
structures for that. So, in keeping with its structure namesake
'abx500_bm_data', we rename it to 'bm' here. Using similar logic,
we're also renaming 'bmdevs_of_probe' to the more device specific
'ab8500_bm_of_probe'.

Also, this is not something part of hardware specs, but is included to cater
some board mistakes or quirks.
So, better get rid of it. This is earlier discussed here:

The Arizona CODECs contain a haptics module providing vibration feedback
support. Implement basic support for this, providing simple start/stop and
signal magnitude control.
Since the output path for haptics is routed through the CODEC audio routing
it is modelled as a signal generator within ASoC, the haptics driver calls
DAPM to start and stop the output drivers. An appropriate output path must
be configured via ALSA to connect the haptics source to the correct output.
Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
Some other device functions need to integrate with signal sources in the
audio portion (primarily for haptics) so allow CODEC to export the DAPM
context by pointing to it from the core driver.

A driver for the apb-soc registers is needed by the clock
infrastructure code to configure and control clocks on the sta2x11
chip.
Since some of the functions in sta2x11-mfd.c were almost identical
for the two existing platform devices, the following changes
have been performed to avoid further code duplication while
adding the apb-soc-regs driver:
* The sctl_regs and apbreg_regs fields in struct sta2x11_mfd
have been turned into just one array of pointers accessed by
device index.
* Platform probe methods have become one-liners invoking a
common probe with the device's index as second parameter.
* For loops have been inserted where the same operations
were performed for each of the two bars of a pci device.
* The apbreg_mask and sctl_mask functions were almost identical,
so they were turned into inline functions invoking a common
__sta2x11_mfd_mask() with the platform device's index as last
parameter. To do this, enum sta2x11_mfd_plat_dev has been declared in
sta2x11-mfd.h and more device types have been added to it.

Moving regulator node parsing to regulator driver in place
of parsing it on mfd driver.
The motivation for this change are:
- MFD core driver should not depends on regulator and able
to instantiate device without regulator.
- The API for matching regulators are in regulator core and
it is good that regulator driver only calls this API.
- Regulator specific support should be in regulator driver only
to ease any enhancement/modification for regulators.
- The regulator driver is now registered as mfd sub device and
all regulator registration is done from single probe call.

and partly because of constantly developed ASoC and ARM stuff.
Some highlights:
- Introduced the helper function and documentation for exposing the
channel map via control API, as discussed in Plumbers; most of PCI
drivers are covered, will follow more drivers later
- Most of drivers have been replaced with the new PM callbacks (if
the bus is supported)
- HD-audio controller got the support of runtime PM and the support of
D3 clock-stop. Also changing the power_save option in sysfs kicks
off immediately to enable / disable the power-save mode.
- Another significant code change in HD-audio is the rewrite of
firmware loading code. Other than that, most of changes in HD-audio
are continued cleanups and standardization for the generic auto
parser and bug fixes (HBR, device-specific fixups), in addition to

As usual we have a few new drivers:
- TI LP8788
- TI OMAP USB TLL
- Maxim MAX8907
- SMSC ECE1099
- Dialog Semiconductor DA9055
- A simpler syscon driver that allow us to get rid of the anatop one.
Drivers are also gradually getting Device Tree and IRQ domain support.
The following drivers got DT support:
- palmas, 88pm860x, tc3589x and twl4030-audio
And those ones now use the IRQ domain APIs:
- 88pm860x, tc3589x, db8500_prcmu
Also some other interesting changes:
- Intel's ICH LPC now supports Lynx Point
- TI's twl4030-audio added a GPO child
- tps6527 enabled its backlight subdevice
- The twl6030 pwm driver moved to the new PWM subsystem
And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x, palmas,
ab8500, wm8994, wm5110, max8907 and the tps65xxx family.

- A number of cleanup series for OMAP, moving and removing some

- Final removal of all non-DT boards for Tegra, it is now
device-tree-only!
- Removal of a stale platform, nxp4008. It's an old mobile chipset
that is no longer in use, and was very likely never really used with
a mainline kernel. We have not been able to find anyone interested

The TPS65217 chip contains a boost converter and current sinks which can be
used to drive LEDs for use as backlights. Expose this functionality via the
backlight API.
Tested on an AM335x based custom board with a single WLED string, using
different values for ISEL and FDIM (though it would be hard to tell the
difference except for the value in WLEDCTRL1). Both instantiation through the
device tree and by passing platform data have been tested. Testing has been
done with an Androidized 3.2 kernel from the rowboat project. Koen Kooi

TI LP8788 PMU provides regulators, battery charger, ADC,
RTC, backlight driver and current sinks.
This MFD patch supports the I2C communication using the regmap,
the interrupt handling using the linear IRQ domain and
configurable platform data structures for each driver module.
(Driver Architecture)
< mfd devices >
LP8788 HW .......... mfd .......... regulator drivers
I2C power supply driver
IRQs iio adc driver

current sink drivers
o regulators : LDOs and BUCKs
o power supply : Battery charger
o iio adc : Battery voltage/temperature
o rtc : RTC and alarm
o backlight
o current sink : LED and vibrator
All MFD device modules are registered by LP8788 MFD core driver.
For sharing information such like the virtual IRQ number,
MFD core driver uses the resource structure.
Then each module can retrieve the specific IRQ number and detect it
in the IRQ thread.
Configurable platform data is handled in each driver module.

The Tegra code-base has contained both a legacy DMA and a dmaengine
driver since v3.6-rcX. This series flips Tegra's defconfig to enable
dmaengine rather than the legacy driver, and removes the legacy driver
and all client code.
The branch is based on v3.6-rc6 in order to pick up a bug-fix to the
ASoC Tegra PCM driver that's required for audio to work correctly when
using dmaengine.

Add regmap based syscon driver.
This is usually used for access misc bits in registers which does not belong
to a specific module, for example, IMX IOMUXC GPR and ANATOP.
With this driver, client can use generic regmap API to access registers
which are registered into syscon.

The MAX8907 is an I2C-based power-management IC containing voltage
regulators, a reset controller, a real-time clock, and a touch-screen
controller.
The original driver was written by:
* Gyungoh Yoo <jack.yoo@maxim-ic.com>
Various fixes and enhancements by:
* Jin Park <jinyoungp@nvidia.com>
* Tom Cherry <tcherry@nvidia.com>
* Prashant Gaikwad <pgaikwad@nvidia.com>
* Dan Willemsen <dwillemsen@nvidia.com>
* Laxman Dewangan <ldewangan@nvidia.com>
During upstreaming, I (swarren):
* Converted to regmap.
* Converted to regmap-irq.
* Allowed probing from device tree.
* Renamed from max8907c->max8907, since the driver covers at least the
C and B revisions.
* General cleanup.
