Commit 65de7654d3 ("iio: iio: Fix iio_channel_read return if
channel havn't info") added a check for valid info masks.
This patch adds missing channel info masks for all ADC channels.
Otherwise, iio_read_channel_raw() would return -EINVAL when called
by consumer drivers.
Note that the change of _processed to _raw actually fixes an ABI abuse
in the original driver where it was used to avoid some special handling
rather than because it was correct.

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.

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.

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

Jonathan writes:
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.

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()

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.

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.

with touchscreen channels. Then if ADC_LCD register is not read quickly,

To remove this temporal constraint, the conversion value is taken from

This patch control special clock for ADC in Exynos series's FSYS block.
If special clock of ADC is registerd on clock list of common clk framework,
Exynos ADC drvier have to control this clock.
Exynos3250/Exynos4/Exynos5 has 'adc' clock as following:
- 'adc' clock: bus clock for ADC
Exynos3250 has additional 'sclk_adc' clock as following:
- 'sclk_adc' clock: special clock for ADC which provide clock to internal ADC
Exynos 4210/4212/4412 and Exynos5250/5420 has not included 'sclk_adc' clock
in FSYS_BLK. But, Exynos3250 based on Cortex-A7 has only included 'sclk_adc'

First round of new drivers, cleanups and functionality for the 3.17 cycle.
New drivers
* t5403 barometric pressure sensor
* kxcjk1013 accelerometer (with a locking followup fix).
* ak09911 digital compass
Documentation
* ABI docs for proximity added (interface has been there a long time but
somehow snuck through without being documented)
* Move iio-trig-sysfs documentation out of staging (got left behind when
the driver moved some time ago).
Cleanups
* drop the timestamp argument from iio_trigger_poll(_chained) as
nothing has been done with it for some time.
* ad799x kerneldoc for ad799x_chip brought up to date.
* replace a number of reimplementations of the GENMASK macro and
use the BIT macro to cleanup a few locations.
* bring the iio_event_monitor example program up to date with new
device types.
* fix some incorrect function prototypes in iio_utils.h example code.
* INDIO_RING_TRIGGERED to INDIO_BUFFER_TRIGGERED fix in docs. This
got left behind after we renamed it a long time back.
* fix error handling in the generic_buffer example program.
* small tidy ups in the iio-trig-periodic-rtc driver.
* Allow reseting iio-trig-periodic-rtc frequency to 0 (default) after
it has changed.
* Trivial tidy ups in coding style in iio_simply_dummy
A mixed bag of fixes, many of which feel just to late for 3.15.
* hid sensors - some devices need a feature report request in order to
change power state. This isn't part of the spec, but has been observed
on several devices and does no harm to others.
* mpl3115 has had two errors in the buffer description fixed. The presure is
signed, not unsigned and the temperature has 12 bits rather than 16.
These could lead to incorrect interpretation of the data in userspace.
* tsl2x7x - the high byte of the proximity thresholds should be written along
with the low byte (which was). This could lead to interesting results
with large thresholds.
* twl4030 - a flag to specify processed values were required was not set
when initializing a reading. As such values returned were in an unknown
state. Fixed by simply initializing it appropriately.
* IIO_SIMPLE_DUMMY_BUFFER did not select IIO_BUFFER leading to randconfig
build errors.
* ak8975 was applying an unwanted le16_to_cpu conversion as the i2c framework
already performs one. As such for big endian systems, the bytes would be
in the wrong order in the magnetic field measurements reported.
* mxs-lradc - the controllable voltage dividers were not enabled / disabled for
later channels than the first one during conversion.
* at91_adc error handling returned -ENOMEM in a u8. Return value of
at91_adc_get_trigger_value_by_name changed to int thus allowing -ENOMEM and
also original values to be returned.
* mcb - mcb_request_mem returns and ERR_PTR but the caller was checking for
NULL to detect an error.

Here is the big staging driver pull request for 3.16-rc1.
Lots of stuff here, tons of cleanup patches, a few new drivers, and some
removed as well, but I think we are still adding a few thousand more
lines than we remove, due to the new drivers being bigger than the ones
deleted.
One notible bit of work did stand out, Jes Sorensen has gone on a tear,
fixing up a wireless driver to be "more sane" than it originally was
from the vendor, with over 500 patches merged here. Good stuff, and a
number of users laptops are better off for it.
All of this has been in linux-next for a while.

A quite large set of SoC updates this cycle. In no particular order:
- Multi-cluster power management for Samsung Exynos, adding support for
big.LITTLE CPU switching on EXYNOS5
- SMP support for Marvell Armada 375 and 38x
- SMP rework on Allwinner A31
- Xilinx Zynq support for SOC_BUS, big endian
- Marvell orion5x platform cleanup, modernizing the implementation and
moving to DT.
- _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
that their platform can be enabled in the same kernel binary as most
of the other v7 platforms in the tree. \o/ The work isn't quite complete,
there's some driver fixes still needed, but the basics now work.
New SoC support added:
- Freescale i.MX6SX
- LSI Axxia AXM55xx SoCs
- Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800
- STi STIH407
Plus a large set of various smaller updates for different platforms. I'm

Not setting the raw parameter in the request causes it to be randomly
initialized to a value that might be different from zero or zero. This leads to
values that are randomly either raw or processed, making it very difficult to

case where the hardware doesn't support it a value of 0 would lead to some
nasty issues. The patch sets it to the specified default of msecs.
* Anon inodes were used by IIO without being explicitly selected. This has
been true for a long time so it clearly only effects rather unusual
configurations (rand configs)
* at91 requires the input subsytem but this wasn't explicity in the Kconfig.
* A couple of parts supported by the max1363 driver were using the wrong
