iio: Move buffer registration to the core
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.

These changes are needed to support the functionality of a pedometer.
A pedometer has two basic functionalities: step counter and step detector.
The step counter needs to be enabled and then it will count the steps
in its hardware register. Whenever the application needs to check
the step count, it will read the step counter register. To support the
step counter a new channel type STEPS is added. Since the pedometer needs
to be enabled first so that the hardware can count and store the steps,
we need a specific ENABLE channel info mask.
The step detector will generate an interrupt each time a step is detected.
To support this functionality we add a new event type INSTANCE.

detector see:

staging: comedi: prepare support for per-file read and write subdevices
Comedi devices may have several subdevices that support "read" and/or
"write" asynchronous commands that use the "read" or "write" file
operations for data transfer. The low-level Comedi drivers may nominate
a default "read" subdevice and/or a default "write" subdevice, but it
may have other subdevices that support asynchronous commands.
The Comedi core provides a somewhat clunky mechanism to provide access
to the asynchronous command support of the non-default subdevices. When
a low-level device is "attached" to a core Comedi device, it dynamically
allocates a minor device number for each of the subdevices that support
asynchrounous commands and associates them with files created in SysFS
named "comediX_subdY", where "X" is the minor device number of the main
comedi device, and "Y" is the subdevice number. An application can open
these subdevice-specific files and they behave like the regular
"comediX" files except that the "read" and/or "write" subdevice may be
different to the default chosen by the low-level driver.
This patch adds a layer of indirection between the file object and the
comedi device object to allow the current "read" and/or "write"
subdevice to be altered after opening the Comedi device, on a per-file
object basis. The advantage is that an application only needs to open
the main Comedi device file and can then choose which subdevice it wants
to "read" or "write". The main Comedi device file can be opened more
than once, and each file object can choose the "read" and "write"
subdevices independently.
The new `struct comedi_file` is created on "open" and freed on
"release". It includes pointers to the main Comedi device structure,
and to the current "read" and "write" subdevice structures (which may be
NULL). It also has information to keep track of when a low-level device
has been attached or detached since the previous time the file object
was used. In that case, the current "read" and "write" subdevices in
the `struct comedi_file` will be changed to the new defaults (or set to
NULL). (The change to new defaults is done by `comedi_file_reset()`.
The checking for attach/detach is done by `comedi_file_check()` which
will call `comedi_file_reset()` if there have been any attach/detach
operations since the previous call.)
A subsequent patch will add the ioctls to change the current "read" and
"write" subdevices.

Merge tag 'iio-for-3.19a' of git://git./linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First round of new drivers, features and cleanups for IIO in the 3.19 cycle.
New drivers / supported parts
* rockchip - rk3066-tsadc variant
* si7020 humidity and temperature sensor
* mcp320x - add mcp3001, mcp3002, mcp3004, mcp3008, mcp3201, mcp3202
* bmp280 pressure and temperature sensor
* Qualcomm SPMI PMIC current ADC driver
* Exynos_adc - support exynos7
New features
* vf610-adc - add temperature sensor support
* Documentation of current attributes, scaled pressure, offset and
scaled humidity, RGBC intensity gain factor and scale applied to
differential voltage channels.
* Bring iio_event_monitor up to date with newer modifiers.
* Add of_xlate function to allow for complex channel mappings from the
device tree.
* Add -g parameter to generic_buffer example to allow for devices with
directly fed (no trigger) buffers.
* Move exynos driver over to syscon for PMU register access.
Cleanups, fixes for new drivers
* lis3l02dq drop an unneeded else.
* st sensors - renam st_sensors to st_sensor_settings (for clarity)
* st sensors - drop an unused parameter from all the probe utility
functions.
* vf610 better error handling and tidy up.
* si7020 - cleanups following merge
* as3935 - drop some unnecessary semicolons.
* bmp280 - fix the pressure calculation.

iio: Add ABI documentation for scaled voltage
This patch adds an entry in ABI documentation for in_voltage-voltage_scale.
It has at least one user driver, adis16220, in accel driver.

iio:pressure:bmp280: fix pressure calculation
According to the datasheet and as defined in struct bmp280_comp_press, dig_p1 is
of type u16, while dig_p2 to dig_p9 are of type s16. In
bmp280_read_compensation_press(), values read from the device were treated as
the wrong type.
In bmp280_read_press() the fractional part of the measured pressure is
calculated wrong. A better way is to use *val for the raw pressure and *val2 for
the quotient and let the core do the proper conversion using IIO_VAL_FRACTIONAL.

iio: adc: exynos_adc: Add support for exynos7
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.
