Pull staging driver updates from Greg KH:
"Here's the big staging driver patchset for 4.1-rc1.
There's a lot of patches here, the Outreachy application period
happened during this development cycle, so that means that there was a
lot of cleanup patches accepted. Other than the normal coding style
and sparse fixes here, there are some driver updates and work toward
making some of the drivers into "mergable" shape (like the Unisys
drivers.)
All of these have been in linux-next for a while"

Depending on conversion mode used, the ADC clock (ADCK) needs
to be below a maximum frequency. According to Vybrid's data
sheet this is 20MHz for the low power conversion mode.
The ADC clock is depending on input clock, which is the bus
clock by default. Vybrid SoC are typically clocked at at 400MHz
or 500MHz, which leads to 66MHz or 83MHz bus clock respectively.
Hence, a divider of 8 is required to stay below the specified
maximum clock of 20MHz.
Due to the different bus clock speeds, the resulting sampling
frequency is not static. Hence use the ADC clock and calculate
the actual available sampling frequency dynamically.
This fixes bogous values observed on some 500MHz clocked Vybrid
SoC. The resulting value usually showed Bit 9 being stuck at 1,
or 0, which lead to a value of +/-512.

First set of new drivers, cleanups and functionality for IIO in the 4.1 cycle.
New drivers
* CM3323 color sensor.
* MS5611 pressure and temperature sensor.
New functionality
* mup6050 - create mux clients for devices described via ACPI. The reasoning
and approach taken in this patch are complex. Basically there is no
otherway of finding out what is there than by some esoteric look ups in
the ACPI data.
* cm3232 - PM support
* itg3200 - suspend/resume support
* mcp320x - add more ADCs to the kconfig to reflect what the driver supports
(this patch and the bindings got left behind when the support was added
a while back).
Docs / utils
* ti-adc128s052 - DT bindings.
* mcp3422 - DT bindings.
* mcp320x - DT bindings
* ABI docs for event threshold scale attributes, in_magn_offset, proximity
scan_element and thresh falling/rising values for accelerometers. All
elements long in use that have slipped by being explicitly documented.
* Tidy up the tools previously in drivers/staging/iio/Documentation and move
them out to /tools/iio. Yet another move that should have happened long ago.
This time Roberta Dobrescu did the leg work. Thanks!
Core Cleanups
* Export userspace IIO headers. We should have done the appropriate header
splitting a long time ago. Thanks to Daniel for sorting this out.
* Refactor the registring of attributes for buffers to move all non-custom
ones to a vector allowing easier additions to the current set in the future.
Driver Cleanups
* gpiod related cleanups. Make use of the additional parameter to specify
initial direciton to avoid extra code.
* bmc150 - Various refactorings to reduce code repitition and prepare for
hardware buffer support. Some of these cleanups are good even
without the new functionality.
* kmx61 - direct use of index to an array avoiding a structure element which
was always the index to an element in an array of that structure.
* vf610 - avoid incorrect type for return from wait_for_completion_timeout.
* gp2ap020a00f - use put_unaligned_le32 for slight code simplification.
* ade7754 - improve error handling including suppressing some build warnings.
* ade7759 - improve error handling including suppressing some build warnings.
* hmc5843 - Long line and indentation fixes. Also some constifying of various
constant data.
* ade7854 - 80+ character line splitting.
* ad2s1210 - fix wrong printf format string.
* mxs-lradc - fix wrong printf format string.
* ade7954-i2c - code alignment fixes and other trivial but worthwhile bits.
* periodic rtc trigger - make the frequency type an unsigned int as it
is always treated as such.
* jsa1212 - constify struct regmap_config as it is constant.
* ad7793 - typo in the MODULE_DESCRIPTION
* mma9551 - check gpiod_to_irq errors. Note that this doesn't actually cause
any trouble but is worth tidying up as obviously incorrect.
* mlx90614 - refactor the register symbols to make it clear which reads are to
RAM not PROM.

This patch makes the initial changes required to workaround TSC-false
pen-up interrupts. It is required to implement these changes in order to
remove udelay in the TSC interrupt handler and false pen-up events. The
charge step is to be executed immediately after sampling X+. Hence TSC is
made to use higher numbered steps (steps 5 to 16 for 5 co-ordinate
readouts, 4 wire TSC configuration) and ADC to use lower ones. Further X
co-ordinate readouts must be the last to be sampled, thus co-ordinates are
sampled in the order Y-Z-X.

First round of IIO new drivers, cleanups and functionality for the 3.20 cycle take 2
Updated pull request with Daniel's fix on top for the power management
Kconfig changes that had snuck in since last update of the IIO tree
worked it's way through from mainline.
Original pull message
New device support
* jsa1212 proxmity / ambient light sensor
* SM08500 supported added to the kxcjk-1013 accelerometer driver
* KMX61 Accelerometer/Magnetometer. This took a somewhat rocky path
being first merged, then reverted for a rewrite after a discussion of
how to support additional functionality and finally being merged prior
to some last reviews coming in, with resultant follow up patches.
* Freescale mma9551l driver (minor follow up warning supression patch).
* Semtech SX9500 proximity device driver.
* ak8975 gains support for ak09911 and ak09912 and drop the standalone driver
for the ak09911.
New functionality
* Dummy driver gains some virtual registers making it more flexible.
* IIO_ACTIVITY channel types, with modifiers running, walking etc. This is
to support on chip motion clasifiers. As such it is in the form of a
confidence percentage. The only devices so far only do binary decisions
but this gives us room when other devices give more nuanced clasification.
* IIO_EV_DIR_NONE type for events where there is no obvious direction.
First case is step detection.
* IIO_STEPS channel type for pedometers.
* ENABLE mask element used to control turning on counting types such as
the pedometer that need a 'start point'.
* INSTANCE event type to support things that happen once.
* info element for height calibration (used in various motion estimation
algorithms). Note heigh tof use
* dummy driver demonstration of the use of all the new bits above.
* event monitor support for the new events.
* inv_mpu6050 gains an i2c mux to allow bypassing the device to access
additional devices connected on the other side of it. Note that in
Windows these are handled by firmware on the device and not exposed
directly.
* inv_mpu6050 gains ACPI enumeration.
* inkern interface gains iio_write_channel_raw to allow in kernel users
of DAC functionality via a simple wrapper.
* Document input current readings in the ABI docs.
* Add an error message when we get an out of range error in device tree
processing for the in kernel interfaces. Basically a device tree debugging
aid.
* Add a sanity check that a scan index for a channel is unique during
registration. There to help catch bugs as this should never happen
in a bug free driver.
Cleanups and fixlets
A rework of buffer registration from Lars - a precursor to some other
upcoming new stuff (a few patches from others rolled in here as well).
* Ensure all drivers register the same channels for the device and buffer.
* Move buffer registration into the core rather than using the old
two step approach. Now we have simple ways of using a unified set channels
for both without requiring channels be exposed by both interface, this
removes a fair bit of boilerplate.
* Stop sca3000 and ad5933 (both in staging) enabling buffer channels by
default. It has long be convention in IIO to startup with no channels
enabled and leave it up to userspace to say what goes in the buffer.
Getting rid of these allows us to drop export of iio_scan_mask_set.
* Drop get_bytes_per_datum from iio_buffer_access_funcs as not been used
for a while.
* Allocate standard buffer attributes in the core rather than in every
driver with a buffer.
* Make the length attribute read only when a driver is not able to set
the length.
* Drop the get_length callback for buffers as it is already available in
struct iio_buffer.
* Drop an unused arguement form iio_kfifo_allocate and add devm allocator
for it.
* some kconfig entries gain anotation with the resulting module name.
* Fix a resulting compile issue in dummy driver due to a stub taking
wrong parameters as a result of the above rework.
* Fix an off by 2 error in copying the core assigned buffer attributes.
Other cleanups,
* Trivial space before comma fixups.
* ak8975 fixlets - none critical. Rework to allow more device support.
* Drop unnecessary sizeof(u8) calls.
* bmp280 - refactor the compensation code to reduce copy operations and
code length. A second patch futher optimized this and performed some
other minor cleanups.
* kxcjk-1013 - various power control cleanups to avoid unnecessary enable
/ disable of device. Make sure it is only controlled at all if CONFIG_PM
is enabled. Also som cleanups of error paths.
* Small cleanups in adf4530 driver - pointless message and unnecessary braces.
* Clarifiy the proximity ABI docs to make it clear it should get bigger
as we move futher away.
* Drop a misleading comment form industrialio-core.c
* Trivial white space cleanups.
* sca3000 looses an unused debug function.
* Fix char unsigned ordering in ad8366
* Increase the sleep time in ad9523 to make it predictable (value didn't
really matter so make it more than 20 msecs)
* mxs-lradc touchscreen property cleanups in device tree are fixed to ensure
the meet all the 'interesting' documentation.
* A couple of cleanups for the staging ad5933 driver to avoid unnecessary
conversion to a processed temperature vlaue in kernel and remove
platform data form the state structure as not needed after probe.
* Fix a wrong scale factor in the docs.
Misc
* Add IIO include files to the maintainers entry.

The timeout value to wait_for_completion_timeout is in jiffies but
the value being passed seems like it was intended to by microseconds
Note that the timeout was extremely long thus it might be too short
now. In any case it probably should be passed through usecs_to_jiffies()
or msecs_to_jiffies()

Pull staging driver updates from Greg KH:
"Here's the big staging tree pull request for 3.19-rc1.
We continued to delete more lines than were added, always a good
thing, but not at a huge rate this release, only about 70k lines
removed overall mostly from removing the horrid bcm driver.
Lots of normal staging driver cleanups and fixes all over the place,
well over a thousand of them, the shortlog shows all the horrid
details.
The "contentious" thing here is the movement of the Android binder
code out of staging into the "real" part of the kernel. This is code
that has been stable for a few years now and is working as-is in the
tens of millions of devices with no issues. Yes, the code is horrid,
and the userspace api leaves a lot to be desired, but it's not going
to change due to legacy issues that we have no control over. Because
so many devices and companies rely on this, and the code is stable,
might as well promote it out of staging.
This was all discussed at the Linux Plumbers conference, and everyone
participating agreed that this was the best way forward.
There is work happening to replace the binder code with something new
that is happening right now, but I don't expect to see the results of
that work for another year at the earliest. If that ever happens, and
Android switches over to it, I'll gladly remove this version.
As for maintainers, I'll be glad to maintain this code, I've been
doing it for the past few years with no problems. I'll send a
MAINTAINERS entry for it before 3.19-final is out, still need to talk
to the Google developers about if they are willing to help with it or
not, last I checked they were, which was good.
All of these patches have been in linux-next for a while with no
reported issues"

"Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes,
just removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There
are some ath9k patches coming in through this tree that have been
acked by the wireless maintainers as they relied on the debugfs
changes.
Everything has been in linux-next for a while"

The ad7991/ad7995/ad7999 does not have a configuration register like the
other devices that can be written and read. The configuration is written as
part of the conversion sequence.

Originally device and buffer registration were kept as separate operations
in IIO to allow to register two distinct sets of channels for buffered and
non-buffered operations. This has since already been further restricted and
the channel set registered for the buffer needs to be a subset of the
channel set registered for the device. Additionally the possibility to not
have a raw (or processed) attribute for a channel which was registered for
the device was added a while ago. This means it is possible to not register
any device level attributes for a channel even if it is registered for the
device. Also if a channel's scan_index is set to -1 and the channel is
registered for the buffer it is ignored.
So in summary it means it is possible to register the same channel array for
both the device and the buffer yet still end up with distinctive sets of
channels for both of them. This makes the argument for having to have to
manually register the channels for both the device and the buffer invalid.
Considering that the vast majority of all drivers want to register the same
set of channels for both the buffer and the device it makes sense to move
the buffer registration into the core to avoid some boiler-plate code in the
device driver setup path.

The ADC on exynos7 is quite similar to ADCv2. The differences are as
follows:
- exynos7-adc has 8 input channels (as against 10 in ADCv2).
- exynos7 does not include an ADC PHY control register.
- Some ADC_CON2 register bits being used in ADCv2 are listed as
reserved in exynos7-adc. This results in a different init_hw
function for exynos7.

Older Rockchip SoCs, at least the rk3066, used a slightly modified saradc
for temperature measurements. This so called tsadc does not contain any
active parts like temperature interrupts and only supports polling the
current temperature. The returned voltage can then be converted by a
suitable thermal driver to and actual temperature and used for thermal
handling.

If touchscreen mode is enabled and a conversion is requested on another
channel, the result in the last converted data register can be a
touchscreen relative value. Starting a conversion involves to do a
conversion for all active channel. It starts with ADC channels and ends
with touchscreen channels. Then if ADC_LCD register is not read quickly,
its content may be a touchscreen conversion.
To remove this temporal constraint, the conversion value is taken from
the channel data register.
