2ca5a8792d iio: light: vcnl4000: update sampling periods for vcnl4040
Vishay has published a new version of "Designing the VCNL4200 Into an
Application" application note in October 2019. The new version specifies
that there is +-20% of part to part tolerance. Although the application
note is related to vcnl4200, according to support the vcnl4040's "ASIC
is quite similar to that one for the VCNL4200".

So update the sampling periods (and comment), including the correct
sampling period for proximity. Both sampling periods are lower. Users
relying on the blocking behaviour of reading will get proximity
measurements much earlier.

Vishay has published a new version of "Designing the VCNL4200 Into an
Application" application note in October 2019. The new version specifies
that there is +-20% of part to part tolerance. This explains the drift
seen during experiments. The proximity pulse width is also changed from
32us to 30us. According to the support, the tolerance also applies to
ambient light.

So update the sampling periods. As the reading is blocking, current
users may notice slightly longer response time.

bc80573ea2 iio: light: vcnl4000: Fix scale for vcnl4040
According to the data sheet the ambient sensor's scale is 0.12 lux/step
(not 0.024 lux/step as used by vcnl4200) when the integration time is
80ms. The integration time is currently hardcoded in the driver to that
value.

   - Enable basic regulator support.
 * dmaengine buffer

     that are self describing.
 * lm3533

   - white space fixes.
   - Mark some constants that aren't always used as __maybe_unused.
   - Drop of ID table guards as they just pervent use under ACPI.

11f1eabee0 cros_ec: treewide: Remove 'include/linux/mfd/cros_ec.h'
This header file now only includes the cros_ec_dev struct, however, is the
'include/linux/platform_data/cros_ec_proto.h' who contains the definition of
all the Chrome OS EC related structs. There is no reason to have a
separate include for this struct so move to the place where other
structs are defined. That way, we can remove the include itself, but also
simplify the common pattern

    #include <linux/mfd/cros_ec.h>
    #include <linux/platform_data/cros_ec_proto.h>

for a single include

    #include <linux/platform_data/cros_ec_proto.h>

The changes to remove the cros_ec.h include were generated with the
following shell script:

    git grep -l "<linux/mfd/cros_ec.h>" | xargs sed -i '/<linux\/mfd\/cros_ec.h>/d'

9dc86c234e First set of IIO new device support, cleanups and features for the 5.5 cycle
Third version with the adis rework set dropped as better to just have
 a fresh version of that at some future date.
 
 The usual mixed backs of new device support being added to drivers,
 long term reworks continuing and little per driver cleanups and
 features.
 
 Also a few trivial counter subsystem tidy ups on behalf of William.
 
 Core new feature
 * Device label support.  A long requested feature no one got around to
   implementing before.  Allows DT based provision of a 'label' that
   identifies a device uniquely within a system.  This differs from existing
   'name' which is meant to be the part number.
 New device support
 * ingenic-adc
   - Support for the JZ4770 SoC ADC including bindings.
 * inv_mpu6050
   - Add support for magnetometer in MPU925x parts.
     Fiddly to do as this is actually a separate device sitting inside the
     package, but with the master device being able to schedule reads etc.
     Will only run if the auxiliary bus is not in use for any other devices.
 
 Features
 * ad7192
   - Userspace calibration controls to do zero and full scale.
 * st_lsm6dsx
   - Enable latched interrupts by default for sensors events with related clear.
   - Motion events and related wakeup source.  This needed quite a bit of
     refactoring as well.
 
 Cleanups and minor features
 * ad7192
   - sysfs ABI docs
 * ad7949
   - Remove code to readback configuration word as driver never actually enabled
     it.
   - Fix incorrect xfer length.  Not actually known to cause problems other
     than wasted bus usage.
 * adis16080
   - Replace core mlock usage with local lock with more appropriate scope.
 * adis16130
   - Remove pointless mlock usage.
 * adis16240
   - Remove include of gpio.h as no gpio usage.
 * atlas-ph-sensor
   - Improve logical ordering of buffer predisable / postenable functions.
     This is part of a longer term rework Alexandru is driving towards.
 * bh1750
   - Fix up a static compiler warning and make the code more readable.
   - yaml conversion of binding + MAINTAINERS entry.
 * bmp280
   - Drop a stray newline.
 * cm36651
   - Drop a redundant assignment
 * itg3200
   - Alignment cleanup.
 * max31856
   - Add missing of_node and parent references, useful to identify the device.
 * sc27xx_adc
   - Use devm_hwspin_lock_request_specific rather than local rolled version.
 * stm32-lptimer counter

82f3015635 iio: light: opt3001: fix mutex unlock race
When an end-of-conversion interrupt is received after performing a
single-shot reading of the light sensor, the driver was waking up the
result ready queue before checking opt->ok_to_ignore_lock to determine
if it should unlock the mutex. The problem occurred in the case where
the other thread woke up and changed the value of opt->ok_to_ignore_lock
to false prior to the interrupt thread performing its read of the
variable. In this case, the mutex would be unlocked twice.

Since commit ebd457d559 ("iio: light: vcnl4000 add devicetree hooks")
the of_match_table is supported but the data shouldn't be a string.
Instead it shall be one of 'enum vcnl4000_device_ids'. Also the matching
logic for the vcnl4020 was wrong. Since the data retrieve mechanism is
still based on the i2c_device_id no failures did appeared till now.

0fe2f2b789 iio: tcs3414: fix iio_triggered_buffer_{pre,post}enable positions
The iio_triggered_buffer_{predisable,postenable} functions attach/detach
the poll functions.

For the predisable hook, the disable code should occur before detaching
the poll func, and for the postenable hook, the poll func should be
attached before the enable code.

The driver was slightly reworked. The preenable hook was moved to the
postenable, to add some symmetry to the postenable/predisable part.

f552fde983 iio: light: bh1750: Resolve compiler warning and make code more readable
Separate the declaration of struct bh1750_chip_info from definition
of bh1750_chip_info_tbl[] in a single statement as it makes the code
hard to read, and with the extra newline it makes it look as if the
bh1750_chip_info_tbl[] had no explicit type.

This change also resolves the following compiler warning about the
unusual position of the static keyword that can be seen when building
with warnings enabled (W=1):

drivers/iio/light/bh1750.c:64:1: warning:
  ‘static’ is not at beginning of declaration [-Wold-style-declaration]

Related to commit 3a11fbb037 ("iio: light: add support for ROHM

840d9f131f mfd / platform: cros_ec: Reorganize platform and mfd includes
There is a bit of mess between cros-ec mfd includes and platform
includes. For example, we have a linux/mfd/cros_ec.h include that
exports the interface implemented in platform/chrome/cros_ec_proto.c. Or
we have a linux/mfd/cros_ec_commands.h file that is non related to the
multifunction device (in the sense that is not exporting any function of
the mfd device). This causes crossed includes between mfd and
platform/chrome subsystems and makes the code difficult to read, apart
from creating 'curious' situations where a platform/chrome driver includes
a linux/mfd/cros_ec.h file just to get the exported functions that are
implemented in another platform/chrome driver.

In order to have a better separation on what the cros-ec multifunction
driver does and what the cros-ec core provides move and rework the
affected includes doing:

 - Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h
 - Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c
   driver from include/linux/mfd/cros_ec.h to a new file
   include/linux/platform_data/cros_ec_proto.h
 - Update all the drivers with the new includes, so
   - Drivers that only need to know about the protocol include
     - linux/platform_data/cros_ec_proto.h
     - linux/platform_data/cros_ec_commands.h
   - Drivers that need to know about the cros-ec mfd device also include
     - linux/mfd/cros_ec.h

we have no way to know the step for all available frequencies.
Even if not complete, we can return a list of known values using the
standard read_avail callback (IIO_CHAN_INFO_SAMP_FREQ) to provide them to
userland.

Now cros_ec_* sensors provides frequencies values in sysfs like this:
"0 min max". 0 is always true to disable the sensor.

  - Tidy up ordering in various buffer related callbacks. This is
    part of a long running effort to simplify the core code.
* stm32-dfsdm:
  - Manage the resolution cleanly in triggerd modes.
  - Add fast mode support which allows more flexible filter choices.
  - Add a comment on the reason for a 16 bit record when technically
    not 'required'.
* st_lsm6dsx
  - Embed device name in the sensor_settings struct as i3c doesn't
    have a convenient name field to use for this.
* xilinx-adc
  - Relax constraints on supported platforms to reflect that this
    can used with FPGAs on PCIe cards and hence many architectures.
* counters/ftm-quaddec
  - Fix some formatting io MODULE_AUTHOR
  - MAINTAINERS entry

Fixes
* tools
  - fix incorrect handling of 32 bit channels.
* sca3000
  - Potential endian bug that is unlikely to bite anyone (be64 host
    seems unlikely for this old part).
* stm32-adc
  - Add vdda-supply. On some boards it needs to be turned on to supply
    the ADC.  DT bindings included.
* stm32-dfsdm
  - Fix output resolution to work with filter orders other than 3.
  - Fix output datatype as it's signed and previously claimed not to be.
