This is a follow up patches after adding i2c mux adapter for bypass
mode. Potentially many different types of sensor can be attached to
INVMPU6XXX device, which can be connected to main cpu i2c bus in
bypass mode.
Why do we need this?
The system ACPI table entry will consist of only one device for
INV6XXX, assuming that this driver will handle all connected sensors.
That is not true for the Linux driver. There are bunch of IIO drivers
for each sensors, hence we created a mux on this device. So to load
these additional drivers, we need to create i2c devices for them
in this driver using this mux adapter.
There are multiple options:
1. Use the auto detect feature, this needs a new i2c class for the
adapter as the existing HWMON class is not acceptable. Also the
autodetect has overhead of executing detect method for each
matching class of adapters.
This is a simple implementation. This option was previously submitted
with not a happy feedback.
2. Option is use ACPI magic and parse the configuration data. What
we need to create a i2c device at a minimum is address and a name.
Address can be obtained for secondary device in more or less in a
standard way from using _CRS element. But there is no name. To get
name we need to process proprietary vendor data. Not having name is
not fun, as you have to create device using the device name of
INVN6XXXX, respecting driver duplicate name space restriction.
Also each client driver needs to have this name in the id table.
Since multiple driver can be loaded, the driver should be able to
detect its presence and gracefully exit for the other client driver
to take it over.
So we use two step process:
- Use DMI to id platform and parse propritery data. This is not uncommon
for many x86 platform specific driver. We will get both name and address.
The change created necessary infrastructure to add more properitery vendor
data parsing.
- If DMI match fails, then create device on INV6XXX-client (we can't
create with same name as INV6XXX as it will cause duplicate name and driver
model will reject.) With this each client sensor driver which needs to get
attached via INV6XXXX, need this name in the id table and detect the
physical presence of sensor in probe and exit if not found.

Jonathan writes:
Second round of IIO new drivers, functionality and cleanups for the 3.20 cycle.
New drivers and device support:
* Capella cm3232 ambient light sensor driver.
* Freescale MMA9553 pedometer and activity monitor. Note this involved a
refactor of the mma9551 driver to pull out shared elements.
* Samsung sensor hub (as used in the galaxy gear 2 watch) Core support
and initial drivers (gyro and accelerometer) more to follow.
An additional fix was applied on top of this for a build issue
thrown up by the autobuilders on some platforms.
* Cosmic Circuits 10001 ADC driver
* Qualcomm SPMI PMIC voltage ADC driver (current adc merged a while back).
* Add binding for AK8963 (in capitals) as unfortunately there are bios'
out there not using lower case.
New functionality
* Add newe operating mode to the core to allow for non triggered software
buffers. This is mostly semantics as previously drivers just claimed they
had a hardware buffer (when they didn't).
* Add distance channel type.
* Add energy channel type.
* Add velocity channel type and IIO_MOD_ROOT_SUM_SQUARED (i.e. speed when
our channel type is velocity).
* Add _debounce_count and _debounce_time filter attributes. Only really
make sense for counting types of measurements. First use is for avoiding
miss detection of steps prior to walking.
* Add change event type. This replaces the briefly present INSTANCE type
(which hadn't gained any users). It is more generic as it allows for
events say every 10 steps rather than every step.
* Add _calibweight attributes to the ABI (and core support). Used by
activity monitors to estimate energy use. Can imagine there will be
other uses for this one.
Driver new functionality
* mma9551 gains runtime pm support.
* hid-sensors gain PM support.
Cleanup
* Change calibheight unit to m from cm. As there are no prior users
and this was inconsistent with other distance units, it makes sense
to fix it before hte mma9553 driver which uses it.
* mpu6050 cleanups and devm_ use.
* as3935 switch over to PM ops.
* Fix a few format strings for signed vs unsigned.
* Fix tcs3414 missindentation
* Typo in industrialio-event
* Stop requiring IIO_TRIGGER for IIO_KFIFO_BUF as we have drivers that don't
need it. No one is quite sure why that dependency was there and it
seems to not matter.

Add support for Freescale MMA9553L Intelligent Pedometer Platform.
The following functionalities are supported:
- step counter (counts the number of steps using a HW register)
- step detector (generates an iio event at every step the user takes)
- activity recognition (rest, walking, jogging, running)
- speed
- calories
- distance
To get accurate pedometer results, the user's height, weight and gender
need to be configured.

The core VM already knows about VM_FAULT_SIGBUS, but cannot return a
"you should SIGSEGV" error, because the SIGSEGV case was generally
handled by the caller - usually the architecture fault handler.
That results in lots of duplication - all the architecture fault
handlers end up doing very similar "look up vma, check permissions, do
retries etc" - but it generally works. However, there are cases where
the VM actually wants to SIGSEGV, and applications _expect_ SIGSEGV.
In particular, when accessing the stack guard page, libsigsegv expects a
SIGSEGV. And it usually got one, because the stack growth is handled by
that duplicated architecture fault handler.
However, when the generic VM layer started propagating the error return
from the stack expansion in commit fee7e49d4514 ("mm: propagate error
from stack expansion even for guard page"), that now exposed the
existing VM_FAULT_SIGBUS result to user space. And user space really
expected SIGSEGV, not SIGBUS.
To fix that case, we need to add a VM_FAULT_SIGSEGV, and teach all those
duplicate architecture fault handlers about it. They all already have
the code to handle SIGSEGV, so it's about just tying that new return
value to the existing code, but it's all a bit annoying.
This is the mindless minimal patch to do this. A more extensive patch
would be to try to gather up the mostly shared fault handling logic into
one generic helper routine, and long-term we really should do that
cleanup.
Just from this patch, you can generally see that most architectures just
copied (directly or indirectly) the old x86 way of doing things, but in
the meantime that original x86 model has been improved to hold the VM
semaphore for shorter times etc and to handle VM_FAULT_RETRY and other
"newer" things, so it would be a good idea to bring all those
improvements to the generic case and teach other architectures about
them too.

The pedometer needs to filter out false steps that might be generated by
tapping the foot, sitting, etc. To do that it computes the number of
steps that occur in a given time and decides the user is moving only
if this value is over a threshold. E.g.: the user starts moving only
if he takes 4 steps in 3 seconds. This filter is applied only when
the user starts moving.
A device that has such pedometer functionality is Freescale's MMA9553L:
http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf.
To export this feature, this patch introduces IIO_CHAN_INFO_DEBOUNCE_COUNT
and IIO_CHAN_INFO_DEBOUNCE_TIME. For the pedometer, in_steps_debounce_count
will specify the number of steps that need to occur in
in_steps_debounce_time seconds so that the pedometer decides the user is
moving.

My previous patches deleting logger and alarm-dev from staging
missed the android Makefile.
This patch cleans up the Makefile to remove the now non-existent
files.

With the relase of Lollipop, Android no longer
requires the logger driver.
There are three patches which the android dev's
still need before they drop logger on all their
devices:
[PATCH v4 1/5] pstores: use scnprintf
[PATCH v2 2/5] pstore: remove superfluous memory size check
[PATCH 3/5] pstore: handle zero-sized prz in series
[PATCH v4 4/5] pstore: add pmsg
[PATCH 5/5] pstore: selinux: add security in-core xattr support for pstore and debugfs
But these seem to have been acked and are hopefully
queued for upstream.
So this patch removes the logger driver from staging.
