ad5761 is a 1-channel DAC with configurable output range.
The driver uses the regulator interface for its voltage ref.
It shares its register layout with ad5761r, ad5721 and ad5721r.
Differences:
ad5761* are 16 bit, ad5721* are 12 bits.
ad57*1r have an internal reference.

This adds freefall event detection to the supported devices. It adds
the in_accel_x&y&z_mag_falling_en iio event attribute, which activates
freefall mode.
In freefall mode, the current acceleration magnitude (AND combination
of all axis values) is compared to the specified threshold.
If it falls under the threshold (in_accel_mag_falling_value),
the appropriate IIO event code is generated.
This is what the sysfs "events" directory for these devices looks
like after this change:
-rw-r--r-- 4096 Oct 23 08:45 in_accel_mag_falling_period
-rw-r--r-- 4096 Oct 23 08:45 in_accel_mag_falling_value

mcp320x driver supports the pseudo-differential mode by
in_voltage'IN+'-voltage'IN-'_raw where (IN+, IN-) = (0, 1), (2, 3), ...
mcp320x chips except MCP3X01 can also select swapped IN+ and IN-
pairs in the pseudo-differential mode.
i.e. in_voltage'IN+'-voltage'IN-'_raw where (IN+, IN-) = (1, 0),
(3, 2), ...
If the voltage level of IN+ is equal to or less than IN-, the
resultant code will be 000h. So it is useful to provide these, too.

Most ST MEMS Sensors that support interrupts can also handle sending
an active low interrupt, i.e. going from high to low on data ready
(or other interrupt) and thus triggering on a falling edge to the
interrupt controller.
Set up logic to inspect the interrupt line we get for a sensor: if
it is triggering on rising edge, leave everything alone, but if it
triggers on falling edges, set up active low, and if unsupported
configurations appear: warn with errors and reconfigure the interrupt
to a rising edge, which all interrupt generating sensors support.
Create a local header for st_sensors_core.h to share functions
between the sensor core and the trigger setup code.

MCP4726 is a single channel 12-bit DAC. We can support MCP4726 with
a little changes to mcp4725 driver. In power-down mode, they have
different selection of VOUT pull-down registers.
MCP4726 also has features:
- Output gain options: 1x, 2x
- Voltage reference selection: VDD, VREF (Unbuffered or Buffered)
But these are not supported in this change. (1x gain, VDD is selected)

- Gains of 1, 2, 4 or 8
- Programmable Data Rate Options:
- 15 SPS (16 bits), 60 SPS (14 bits), 240 SPS (12 bits)

Jonathan writes:
Second set of IIO new drivers, functionality and cleanups for the 4.5 cycle.
The big one here is the configfs support which has been a long time in the
works but should allow for cleaner ways to do instantiation of those elements
of IIO that aren't directly connected to specific hardware. Lots of cool new
stuff we can use this for in the works!
New core stuff (basically all configfs support related)
* Configfs support
- Core support (was waiting for a configfs patch that went in around 4.4rc2)
- A little fixlet to add a configfs.h to contain a reference to the
configfs_subsystem structure.
* Some infrastructure to simplify handling of software based triggers
(i.e. ones with no actual hardware associated with them)
* A high resolution timer based trigger. This has been around for years
but until the configfs support was ready we didn't have a sensible way
of instantiating instances of it (the method used for the sysfs_trigger
has never been really satisfactory)
New Device Support
* AMS iAQ Volatile Organic Compounds sensor support.
* Freescale imx7d ADC driver
* Maxim MAX30100 oximeter driver (note that for these devices most of the
smart stuff will be in userspace - effectively they are just light sensors
with some interesting led synchronization as far as the kernel is concerned).
* Microchip mcp3421 support added to the mcp3422 driver.
* TI adc124s021 support added to the adc128s052 driver.
* TI ina219, inda226 power monitors. Note that there is an existing hwmon driver
for these parts, the usecase is somewhat different so it is unclear at this
point if the hwmon driver will eventually be replaced by a bridge from
this driver. In the meantime the Kconfig dependencies should prevent both
from being built.
New driver functionality
* us8152d power management support.
Cleanups, fixups
* Use list_for_each_entry_safe instead of list_for_each_safe with the entry
bit coded longhand.
* Select IRQ_WORK for IIO_DUMMY_EVGEN. This is a fix that somehow got lost
when the driver was moved so lets do it again.
* st-accel - drop an unused define.
* vz89x, lidar - optimize i2c transactions by using a single i2c tranfers
instead of multiple calls where supported (fall back to smbus calls as
before if not).
* Use dev_get_platdata() in staging drivers: tsl2x7x, adcs and frequency
drivers instead of direct access to the structure element.

When setting als only or proximity only modes make sure that we mark the
other component as disabled. This fix is in preparation of adding event
support because that will make it possible to switch between one-shot and
continuous modes and not tracking these correctly may cause faulty

ARCH_SHMOBILE is coming to arm64, which creates new warnings in allmodconfig:

_nbu2ss_writel(&preg->EP_DCR[num].EP_TADR, (u32)pBuffer);
This is clearly a mistake from confusing a dma_addr_t with a pointer,
so the fix is to use the correct types in two places.
The third warning of this kind is a check for an unaligned pointer,
which should be done by casting the pointer to uintptr_t, not int.

The driver uses `struct counter_mode_register_t` to describe the 16-bit
counter mode register as a sequence of bitfield members. The struct
appears as the type of one of the members of `union cmReg`, the other
member of which is of type `unsigned short`, so the driver can
manipulate the register value as a whole, or as individual fields.
Although this is fairly convenient, it's not that conventional. The
code also needs to define the bitfield members in ascending or
descending order of the physical bits, depending on whether bitfields
are little- or big-endian.
Rip all that out and replace it with a bunch of macros to set and mask
out bits of the register value, as that's the more conventional way to
do it. A bonus is that we get rid of a load of CamelCase definitions in
the process.

If the "write" file operation handler, `comedi_write()` is passed 0 for
the amount to write, some error conditions are currently skipped and the
function just returns 0. Change it to check those error conditions and
return an error value if appropriate. The trickiest case is the check
for when the previously set up asynchronous command has terminated with
an error. In that case, `-EPIPE` is returned (as it is for a write of
non-zero length) and the subdevice gets marked as non-busy.
A zero-length write that returns 0 has no other effects, in particular,
it does not cause the subdevice to be marked as non-busy.

In order to perform a "write" file operation, an asynchronous COMEDI
command in the "write" direction needs to have been set up by the
current file object on the COMEDI "write" subdevice associated with the
file object. If there is a "write" subdevice, but a command has not
been set up by the file object (or is has been set-up in the wrong
direction), `comedi_write()` currently returns one of two error values
`-EINVAL` or `-EACCES`. `-EACCES` is returned if the command was set up
by a different subdevice, or somewhat randomly, if a COMEDI
"instruction" is currently being processed. `-EINVAL` is returned in
other cases. Simplify it by returning `-EINVAL` for all these cases.

The "write" file operation handler, `comedi_write()` returns an error
for pretty much any condition that prevents a "write" going ahead. One
of the conditions that prevents a "write" going ahead is that no
asynchronous command has been set up, but that currently results in a
return value of 0 (unless COMEDI instructions are being processed or an
asynchronous command has been set up by a different file object).

`comedi_write()` is the handler for the "write" file operation for
COMEDI devices. It mostly runs without using the main mutex of the
COMEDI device, but uses the `attach_lock` rw_semaphore to protect
against the COMEDI device becoming "detached". A file object can write
data for a COMEDI asynchonous command if it initiated the command. The
COMEDI subdevice is marked as busy when the command is started. At some
point, the "write" handler detects that the command has terminated and
so marks the subdevice as non-busy.
In order to mark the subdevice as non-busy, the "write" handler needs to
release the `attach_lock` rw_semaphore and `acquire the main `mutex`.
There is a vulnerable point between the two, so it checks that the
device is still attached after acquiring the mutex. However, it does
not currently check that the conditions for becoming non-busy still
hold. Add some more checks that the subdevice is still busy with a
command initiated by the same file object, and that the command is in
the correct direction (in case the subdevice supports both "read" and
"write").

Rearrange the code in `comedi_write()` to reduce the amount of
indentation. The code never reiterates the `while` loop once `count`
has become non-zero, so we can check that in the `while` condition to
save an indentation level. (Note that `nbytes` has been checked to be
non-zero before entering the loop, so we can remove that check.) Move
the code that makes the subdevice "become non-busy" outside the `while`
loop, using a new flag variable `become_nonbusy` to decide whether it
needs to be done. This simplifies the wait queue handling so there is a
single place where the task is removed from the wait queue, and we can
remove the `on_wait_queue` flag variable.
