Second set of IIO new device support, features and cleanup for 4.15

New device support
* cros_ec_accel_legacy
  - New driver for this older chromebook accelerometer.
* ds4422 dac driver
  - New driver and bindings for the Maxim ds4422 and ds4424 I2C DACs.
* kxcjk1013
  - Support the KXTF9 accelerometers.
* mcp320x
  - support mcp3550, mcp3551, mcp3553 21 bit ADCs.
* rfd77402
  - new driver for this laser range finder.
* st-sensors-accel
  - add support for the LIS2DW12 accelerometer with bindings
  - add support for the LIS3DHH accelerometer with bindings

New features
* core
  - Drop a duplicate forward declaration in iio.h
* Docs
  - add a clarification of the meaning of IIO_DISTANCE to reflect
    existing use in various range finding devices.
* st-sensors
  - add a register mask for the status register to correctly support
    2 channel devices.
  - decouple the irq1 and irq2 configuration parameters.
  - do not always write the enable_axis register as some newer devices
    are always on and don't support such configuration.
  - split open-drain control for irq1 and irq2
  - make sampling frequency control optional as non all hardware
    supports it.
* st-sensors-gyro
  - support 3 wire SPI mode
* st-sensors-magn
  - support 3 wire SPI mode
* st-sensors-pressure
  - support 3 wire SPI mode.

Cleanups and fixes
* ad7192
  - expand the buffer lock to cover device state protection rather than
    using core mlock to provide the state protection.
ade7753
  - expand the buffer lock to cover device state protection as well
    rather than having an additional lock.
* dummy-evgen
  - Use the new irq_sim infrastructure rather than having our
    own local version of the same thing.
* hid-sensor-trigger
  - avoid touching sensors ever if user hasn't requested it.  This
    is a work around for one reported issue where turning a sensor
    off wasn't sufficient to make it actually switch off.  As we
    have only one report from what looks like buggy hardware we
    are sending this upstream the slow way.
* ina2xx
  - Adhere to the published ABI docs and use Ohms instead of
    microohms.  We don't think that anyone will notice this ABI fix
    but are sending it the slow route to reduce fallout if someone
    does!
* kxcjk1013 - refactors to support the KXTF9 being added.
  - Refactor ODR support.
  - Fix INT_CTRL/INT_SRC1 bit names to match the register name.
  - Extract code for reporting motion events as this isn't present
    on some parts to be supported.
  - Make the sysfs sampling_frequency_available stuff not a fixed
    string so as to allow for it to be chip type dependent.
  - Make the sampling frequency_available per type to match
    the sampling_frequency attributes.
* lsm6dsx - rework prior to new device support.
  - express the max fifo depth in 'scans' rather than bytes.
  - split control of the fifo mode fifo output data rate.
  - move decimator registers into the sensor_settings structure
    as this will make it easier to support devices that don't have
    this function.
  - add a fifo ops datastructure to allow for inter-part variations.
* max30100
  - fix i2c chip address in dt example
* max30102
  - use correct binding name for max30102 in example
* mma8452
  - Rename read/write event value callbacks to be more generic
    reflecting what they actually do now.
* rcar-gyroadc
  - pointer case to fix warnings when moving to 64 bit as this IP is
    present on new 64 bit SOCs
  - enable compile-testing to improve build coverage on this driver.
  - use the of_device_get_match_data helper instead of open coding
* sun4i-gpadc-iio
  - Register in the thermal framework after pm. Otherwise the IP is not
    enabled.
  - Don't fail probing if no thermal DT node is present.
* tsl2x7x
  - renaming tsl2x7x_settings to settings to avoid excessive line
    lengths.
  - Use IIO core to generate the integration_time sysfs attributes
    rather than hand rolling.
* vf6180
  - Move the range check on integration time to the setter function.
  - Refactor the code around integration time to be clearer including
    caching current integration time avoiding unnecessary chip reads.
  - cleanup the als_gain lookup avoiding reading registers on chip.
  - use rounded matching rather than precise values for als_gain
    lookup.
  - Correct the ALS  scale when non-default gain or integration time
    is used.

In fact the above commit didn't cause this regression, but any operation
which cause sensors to wake up would have caused the same issue. So if
user reads the raw sensor data, same issue occurs, with or without this
commit. Only difference is that the above commit by default will trigger
a power up and power down of sensors as part of runtime pm enable
(runtime enable will cause a runtime resume callback followed by
runtime_suspend callback). Previously user has to do some action on
sensors.

On investigation it was observed that the current driver correctly
changing the state of all sensors to power off but then also some sensor
will still send some data. Only option is to never power up any sensor.

Only good option is to:
- Using sysfs interface disable USB as a wakeup device (This will not
need any driver change)

Since some user don't care about sensors. So for those users this change
brings back old functionality. As long as they don't cause any operation
to power up sensors (like raw read or start iio-sensor-proxy service),
the sensors will not be to touched. This is done by delaying run time
enable till user space does some operation with sensors.

Lukas Wunner [Sat, 9 Sep 2017 18:32:41 +0000 (20:32 +0200)]
iio: adc: mcp320x: Add support for mcp3550/1/3

These ADCs are marketed as single-channel 22 bit delta-sigma ADCs, but
in reality their resolution is 21 bit with an overrange or underrange
of 12% beyond Vref.  In other words, "full scale" means +/- 2^20.

This driver does not explicitly signal back to the user when an
overrange or underrange occurs, but the user can detect it by comparing
the raw value to +/- 2^20 (or the scaled value to Vref).

The chips feature an extended temperature range and high accuracy,
low noise characteristics, but their conversion times are slow with
up to 80 ms +/- 2% (on the MCP3550-50).

Hence, unlike the other ADCs supported by the driver, conversion does
not take place in realtime upon lowering CS.  Instead, CS is asserted
for 8 usec to start the conversion.  After waiting for the duration of
the conversion, the result can be fetched.  While waiting, control of
the bus is ceased so it may be used by a different device.

After the result has been fetched and 10 us have passed, the chip goes
into shutdown and an additional power-up delay of 144 clock periods is
then required to wake the analog circuitry upon the next conversion
(footnote below table 4-1, page 16 in the spec).

Optionally, the chips can be used in so-called "continuous conversion
mode":  Conversions then take place continuously and the last result may
be fetched at any time without observing a delay.  The mode is enabled
by permanently driving CS low, e.g. by wiring it to ground.  The driver
only supports "single conversion mode" for now but should be adaptable
to "continuous conversion mode" with moderate effort.

The chips clock out a 3 byte word, unlike the other ADCs supported by
the driver which all have a lower resolution than 16 bit and thus make
do with 2 bytes.  Calculate the word length on probe by rounding up the
resolution to full bytes.  Crucially, if the clock idles low, the
transfer is preceded by a useless Data Ready bit which increases its
length from 24 bit to 25 bit = 4 bytes (section 5.5 in the spec).
Autosense this based on the SPI slave's configuration.

attribute outside the IIO core. This attribute is available in the IIO
core so this patches migrates the attribute to be created by

  its current state. The patch series addresses this by removing all
  duct tape and refactoring it into a workable state.

  The reasons why I ask for inclusion that late in the cycle are:

   1) The code causes lockdep splats vs. hotplug locking which get
      reported over and over. Unfortunately there is no easy fix.

   2) The risk of breakage is minimal because it's already broken

   3) As 4.14 is a long term stable kernel, I prefer to have working
      watchdog code in that and the lockdep issues resolved. I wouldn't
      ask you to pull if 4.14 wouldn't be a LTS kernel or if the
      solution would be easy to backport.

   4) The series was around before the merge window opened, but then got
      delayed due to the UP failure caused by the for_each_cpu()
      surprise which we discussed recently.

  Changes vs. V1:

   - Addressed your review points

   - Addressed the warning in the powerpc code which was discovered late

   - Changed two function names which made sense up to a certain point
     in the series. Now they match what they do in the end.

   - Fixed a 'unused variable' warning, which got not detected by the
     intel robot. I triggered it when trying all possible related config
     combinations manually. Randconfig testing seems not random enough.

late_initcalls and the userspace could be up and running from the initramfs
by that time (with populate_rootfs, which is a rootfs_initcall()). This
could cause problems for the early applications ending up in failure

pages, each pte we tear down maps 1GB.

A hot unplug of one 256MB memory block results in 768MB of memory
