Modelling the RESET line as a regulator supply wasn't a good idea
as it kind of abuses the regulator framework and also makes adaptation
code more complex.
Instead, manage the RESET gpio line directly in the driver. Update
the device tree binding information.
This also makes us easy to migrate to a dedicated GPIO RESET controller
whenever it becomes available.

omap_get_control_dev() is being deprecated as it doesn't support
multiple instances. As control device is present only from OMAP4
onwards which supports DT only, we use phandles to get the
reference to the control device.
Also get rid of "ti,has-mailbox" property as it is redundant and
we can determine that from whether "ctrl-module" property is present
or not. Get rid of has_mailbox from musb_hdrc_platform_data as well.

Add support for new device types and in the process rid of "ti,type"
device tree property. The correct type of device will be determined
from the compatible string instead.
Introduce a compatible string for each device type. At the moment
we support 4 types OTGHS, USB2, PIPE3 (e.g. USB3) and DRA7USB2.
Update DT binding information to reflect these changes.
Also get rid of omap_control_usb3_phy_power(). Just one function
i.e. omap_control_usb_phy_power() will now take care of all PHY types.

We have a fairly large batch of fixes this time around, mostly just due to
various platforms all having a fix or two more than usual.
Worth pointing out are:
- A fix for EDMA on Davinci/OMAP where channel allocation broke with
the DT conversion. Due to some miscommunication we didn't
understand the impact of the breakage, so we were pushing back on it
for 3.12, but it sounds like it's actually breaking quite a few people
out there.
- A bunch of fixes for Marvell platforms, some straggling fixes for
merge window fallout and some fixes for a couple of the platforms
(Netgear RN102 in particular).
- A fix for a race between multi-cluster power management and cpu hotplug
on Versatile Express.
And a bunch of other smaller fixes that all add up.
We'll be switching over into stricter regressions-only mode from here
on out.

The advent of multi-cluster ARM systems requires a mechanism to describe
how in hierarchical terms CPUs are connected in ARM SoCs so that the kernel
can initialize and map resources like IRQs and memory space to specific
group(s) of CPUs.
The CPU topology is made up of multiple hierarchy levels whose bottom
layers (aka leaf nodes in device tree syntax) contain links to the HW
CPUs in the system.
The topology bindings are generic for both 32-bit and 64-bit systems and
lay the groundwork on top of which affinity schemes can be built.
This patch provides the documentation in the kernel required to define the
device tree bindings describing the CPU topology for ARM 32-bit and 64-bit
systems.

Allwinner has electric fuses (efuse) on their line of chips. This driver
reads those fuses, seeds the kernel entropy and exports them as a sysfs
node.
These fuses are most likely to be programmed at the factory, encoding
things like Chip ID, some sort of serial number, etc. and appear to be
reasonably unique.
While in theory, these should be writeable by the user, it will probably
be inconvenient to do so. Allwinner recommends that a certain input pin,
labeled 'efuse_vddq', be connected to GND. To write these fuses however,
a 2.5 V programming voltage needs to be applied to this pin.
Even so, they can still be used to generate a board-unique mac from,
board unique RSA key and seed the kernel RNG.
On sun7i additional storage is available, this is initially used for an
UEFI BOOT key, Secure JTAG key, HDMI-HDCP key and vendor specific keys.
Currently supported are the following known chips:
Allwinner sun4i (A10)
Allwinner sun5i (A10s, A13)

The "mentor,musb" binding isn't documented so I was about
to document it.
The node is missing a few properties for configuration like
"multipoint", "dyn_fifo", "num_eps" or "ram_bits". However
I am not sure "missing" is the right word here because some
of those informations might be obtained from the chip itself
but it is not done (yet).
Further the ePARP 2.3.1 says the matching goes from left to
right taking the fist match. Right now there is jus a driver
for "stericsson,db8500-musb" and none for "mentor,musb".
I'm not 100% that it is simply possible to have a generic
since even for DMA we have ifdefs in the driver between
"generic mentor dma" and "ux500 dma" and I mean within musb
and not the dma code.
For that reason (that I am not sure a generic musb binding
is possible and how its binding / required properties will
look like) and the reason that we have here a minor binding
without a driver to look at I suggest to remove that binding.
If the majority of people prefer to keep this binding I'm
curious how the documentation of the binding should look like.

A number of new drivers and some new functionality + a lot of cleanups
all over IIO.
New Core Elements
1) New INT_TIME info_mask element for integration time, which may have
different effects on measurement noise and similar, than an amplifier
and hence is different from existing SCALE. Already existed in some
drivers as a custom attribute.
2) Introduce a iio_push_buffers_with_timestamp helper to cover the common
case of filling the last 64 bits of data to be passed to the buffer with
a timestamp. Applied to lots of drivers. Cuts down on repeated code and
moves a slightly fiddly bit of logic into a single location.
3) Introduce info_mask_[shared_by_dir/shared_by_all] elements to allow support
of elements such as sampling_frequency which is typically shared by all
input channels on a device. This reduces code and makes these controls
available from in kernel consumers of IIO devices.
New drivers
1) MCP3422/3/4 ADC
2) TSL4531 ambient light sensor
3) TCS3472/5 color light sensor
4) GP2AP020A00F ambient light / proximity sensor
5) LPS001WP support added to ST pressure sensor driver.
New driver functionality
1) ti_am335x_adc Add buffered sampling support.
This device has a hardware fifo that is fed directly into an IIO kfifo
buffer based on a watershed interrupt. Note this will act as an example
of how to handle this increasingly common type of device.
The only previous example - sca3000 - take a less than optimal approach
which is largely why it is still in staging.
A couple of little cleanups for that new functionality followed later.
Core cleanups:
1) MAINTAINERS - Sachin actually brought my email address up to date because
I said I'd do it and never got around to it :)
2) Assign buffer list elements as single element lists to simplify the
iio_buffer_is_active logic.
3) wake_up_interruptible_poll instead of wake_up_interruptible to only wake
up threads waiting for poll notifications.
4) Add O_CLOEXEC flag to anon_inode_get_fd call for IIO event interface.
5) Change iio_push_to_buffers to take a void * pointer so as to avoid some
annoying and unnecessary type casts.
6) iio_compute_scan_bytes incorrectly took a long rather than unsigned long.
7) Various minor tidy ups.
Driver cleanups (in no particular order)
1) Another set of devm_ allocations patches from Sachin Kamat.
2) tsl2x7x - 0 to NULL cleanup.
3) hmc5843 - fix missing > in MODULE_AUTHOR
4) Set of strict_strto* to kstrto* conversions.
5) mxs-lradc - fix ordering of resource removal to match creation
6) mxs-lradc - add MODULE_ALIAS
7) adc7606 - drop a work pending test duplicated in core functions.
8) hmc5843 - devm_ allocation patch
9) Series of redundant breaks removed.
10) ad2s1200 - pr_err -> dev_err
11) adjd_s311 - use INT_TIME
12) ST sensors - large set of cleanups from Lee Jones and removed restriction
to using only triggers provided by the st_sensors themselves from
Dennis Ciocca.
13) dummy and tmp006 provide sampling_frequency via info_mask_shared_by_all.
14) tcs3472 - fix incorrect buffer size and wrong device pointer used in
suspend / resume functions.
15) max1363 - use defaults for buffer setup ops as provided by the triggered
buffer helpers as they are the same as were specified in max1363 driver.

Currently DT compatibility strings of both types can be found in the kernel
sources: <unit>-<soc> and <soc>-<unit>, whereas a unique format should be
followed and the former one is preferred. This patch converts the SDHI
MMC driver and its users to the common standard. This is safe for now, since
ATM no real products are using this driver with DT.

The turn-on time of the regulator depends on the regulator device's
electrical characteristics. Sometimes regulator turn-on time also
depends on the capacitive load on the given platform and it can be
more than the datasheet value.
The driver provides the enable-time as per datasheet.
Add support for configure the enable ramp time through regulator
constraints so that regulator core can take this value for enable
time for that regulator.

The next biggest change is the introduction of the imx thermal driver.
It adds the imx thermal support using Temperature Monitor (TEMPMON)
block found on some Freescale i.MX SoCs. The driver uses syscon
regmap interface to access TEMPMON control registers and calibration

Merge tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux
Pull device tree core updates from Grant Likely:
"Generally minor changes. A bunch of bug fixes, particularly for
initialization and some refactoring. Most notable change if feeding
the entire flattened tree into the random pool at boot. May not be
significant, but shouldn't hurt either"
Tim Bird questions whether the boot time cost of the random feeding may
be noticeable. And "add_device_randomness()" is definitely not some
speed deamon of a function.

This branch contains mostly additions and changes to platform enablement
and SoC-level drivers. Since there's sometimes a dependency on device-tree
changes, there's also a fair amount of those in this branch.
Pieces worth mentioning are:
- Mbus driver for Marvell platforms, allowing kernel configuration
and resource allocation of on-chip peripherals.
- Enablement of the mbus infrastructure from Marvell PCI-e drivers.
- Preparation of MSI support for Marvell platforms.
- Addition of new PCI-e host controller driver for Tegra platforms
- Some churn caused by sharing of macro names between i.MX 6Q and 6DL
platforms in the device tree sources and header files.
- Various suspend/PM updates for Tegra, including LP1 support.
- Versatile Express support for MCPM, part of big little support.
- Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7)
- OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
The code that touches other architectures are patches moving
MSI arch-specific functions over to weak symbols and removal of
ARCH_SUPPORTS_MSI, acked by PCI maintainers.

The compatible string of the kirkwood-i2s driver was chosen as
"marvell,mvebu-audio". Using such a compatible string is not a good
idea, since "mvebu" is the name of a large family of SOCs, in which
new, unknown SOCs will be coming in the future. It is therefore
impossible to know what will be evolutions of this hardware block in
the next generations of the SOCs. For this reason, the recommandation
for compatible strings of on-SOCs devices has always been to use the
name of the oldest SOC that has the hardware block. New SOCs that have
an exactly compatible hardware block can reference it using the same
compatible string. See [1], [2] and [3] for various cases were this
suggestion was made, including from Rob Herring, a Device Tree binding
maintainer.
As an example, there are already small differences between current
generations:
* On Kirkwood, only one interrupt is used for audio.
* On Dove, two interrupts are used, one for audio data and one for
error reporting.
In the near future, I'll be adding audio support to Armada 370, which
allows has the same hardware block (but maybe with minor variants).
Therefore, this patch changes the driver to accept
"marvell,kirkwood-audio" and "marvell,dove-audio" as compatible
strings instead of the too-generic "marvell,mvebu-audio". The reason
for the two different compatible strings is the difference in the
number of interrupts used by the two SOCs for audio.
This Device Tree binding has never been part of a Linux kernel stable
release so far, so it can be changed now without breaking backward
compatibility.

"This is the main drm pull request, I have some overlap with sound and
arm-soc, the sound patch is acked and may conflict based on -next
reports but should be a trivial fixup, which I'll leave to you!
Highlights:
- new drivers:
MSM driver from Rob Clark
- non-drm:
switcheroo and hdmi audio driver support for secondary GPU
poweroff, so drivers can use runtime PM to poweroff the GPUs. This
can save 5 or 6W on some optimus laptops.
- drm core:
combined GEM and TTM VMA manager
per-filp mmap permission tracking
initial rendernode support (via a runtime enable for now, until we get api stable),
remove old proc support,
lots of cleanups of legacy code
hdmi vendor infoframes and 4k modes
lots of gem/prime locking and races fixes
async pageflip scaffolding
drm bridge objects
- i915:
Haswell PC8+ support and eLLC support, HDMI 4K support, initial
per-process VMA pieces, watermark reworks, convert to generic hdmi
infoframes, encoder reworking, fastboot support,
- radeon:
CIK PM support, remove 3d blit code in favour of DMA engines,
Berlin GPU support, HDMI audio fixes
- nouveau:
secondary GPU power down support for optimus laptops, lots of
fixes, use MSI, VP3 engine support
- exynos:
runtime pm support for g2d, DT support, remove non-DT,
- tda998x i2c driver:
lots of fixes for sync issues
- gma500:
lots of cleanups
- rcar:
add LVDS support, fbdev emulation,
- tegra:
just minor fixes"

From Anatolij:
<<
There are cleanups for some mpc5121 specific drivers and DTS files
in preparation to switch mpc5121 clock support to a clock driver
based on common clock framework. Additionally Sebastian fixed the
mpc52xx PIC driver so that it builds when using older gcc versions.
>>
The exynos4 platform is only dt-based since 3.10, we should convert driver data
and ids to dt-based parsing methods. The rotator driver has a limit table to get
size limit of input picture. Each SoCs has slightly different limit value
compared with any others.
For example, exynos4210's max_size of RGB888 is 16k x 16k. But, others have
8k x 8k. Another example the exynos5250 should have multiple of 2 pixel size
for its X/Y axis. Thus, we should keep different tables for each of them.
This patch also includes desciptions of each nodes for the rotator and specifies
a example how to bind it.

Here's the bit staging tree pull request for 3.12-rc1.
Lots of staging driver updates, and fixes. Lustre is finally enabled in
the build, and lots of cleanup started happening in it. There's a new
wireless driver in here, and 2 new TTY drivers, which cause the overall
lines added/removed to be quite large on the "added" side.
The IIO driver updates are also coming through here, as they are tied to
the staging iio drivers.

Not much exciting going on with the regulator API this time around, lots
of driver fixes and enhancements - the main thing is the addition of a
new API to help make the stubbing code do the right thing for missing
regulator mappings.
Highlights:
- A new regulator_get_optional() API call for regulators that can be
absent in normal operation. This currently does nothing but will be
used to improve the stubbing code for unspecified regulators, helping
avoid some of the issues we've seen with adding new regulator support.
- Helpers for devices with multiple linear ranges of voltages in the
same regulator.
- Moved the helpers into a separate file since core.c is getting rather
large.
- New drivers for Dialog DA9210 and DA9063, Freescale pfuze100 and
Marvell 88pm800.

This commit fixes the DT binding for the Armada 370/XP SoC timer.
The previous "marvell,armada-370-xp-timer" compatible is removed and
two new compatible strings are introduced: "marvell,armada-xp-timer"
and "marvell,armada-370-timer".
The rationale behind this change is that the Armada 370 SoC and the
Armada XP SoC timers are not really compatible:
* Armada 370 has no 25 MHz fixed timer.
* Armada XP cannot work properly without such 25 MHz fixed timer
as doing otherwise leads to using a clocksource whose frequency
varies when doing cpufreq frequency changes.
This commit also removes the "marvell,timer-25Mhz" property, given
it's now meaningless.

Let's fix up the msm serial device bindings so that it's clearer
what hardware is supported. Instead of using hsuart (for high
speed uart) let's use uartdm because that matches the actual name
of the hardware. Also, let's add the version information in case
we need to differentiate between different versions of the
hardware in the future. Finally, lets specify that clocks are
required (the clock bindings didn't exist when the original
binding was written) and also specify dma bindings just in case
we want to use it in software. We split the binding into two
files to make it clearer what's required and not required.

initialized, because we need to ensure that the given contiguous blocks
are not yet allocated by kernel. Also it must happen before kernel
mappings for the whole low memory are created, to ensure that there will
be no mappings (for reserved blocks) or mapping with special properties
can be created (for CMA blocks). This all happens before device tree
structures are unflattened, so we need to get reserved memory layout
directly from fdt.
Later, those reserved memory regions are assigned to devices on each
device structure initialization.

Add hardware blinking support to the pca9633 driver.
NOTE: Hardware blinking violates the leds infrastructure
driver interface since the hardware only supports
blinking all LEDs with the same delay_on/delay_off
rates. That is, only the LEDs that are set to blink
will actually blink but all LEDs that are set to blink
will blink in identical fashion. The delay_on/delay_off
values of the last LED that is set to blink will be used
for all of the blinking LEDs. If the hardware doesn't
support the requested blinking pattern, a default of
500ms on and off will be used.
Hardware blinking is disabled by default but can be enabled
by setting the 'blink_type' member in the platform_data
struct to 'PCA9633_HW_BLINK' or by adding the 'nxp,hw-blink'
property to the DTS.

LP8501 can drive up to 9 channels like LP5523.
LEDs can be controlled directly via the I2C and programmable engines are
supported.
LP55xx common driver
LP8501 is one of LP55xx family device, so LP55xx common code are used.
Chip specific data is defined in the structure, 'lp55xx_device_config'.
Differences between LP8501 and LP5523
Different register layout for LED output control and others.
LP8501 specific feature for separate output power selection.
LP8501 doesn't support external clock detection.
Different programming engine data.
LP8501 specific feature - output power selection
Output channels are selected by power selection - Vout or Vdd.
Separate power for VDD1-6 and VDD7-9 are available.
It is configurable in the platform data.
To support this feature, LP55xx DT structure and header are changed.
Device tree binding is updated as well.
LED pattern data
Example pattern data is updated in the driver documentation.

This adds the ROM script addresses for i.MX25, i.MX5x and i.MX6 to the
SDMA driver needed for the driver to work without additional firmware.
The ROM script addresses are SoC specific and in some cases even tapeout
specific. This patch adds the ROM script addresses only for SoCs which
do not have a tapeout specific SDMA ROM, because currently it's unclear
how this case should be handled.

The Allwinner A20 is almost identical to the earlier A10 SoC from
Allwinner on many aspects, including the clocks tree. However, since the
A20 has some additionnal IPs compared to the A10, the clock tree isn't
exactly the same, especially when it comes to the gated clocks
available. We thus need to register different clock gates for the A20.
