commit 76222772
"iio: accel: st_accel: handle deprecated bindings"
attempted to be smart and let users use the old I2C
driver and the new SPI driver, or the old SPI driver and
the new I2C driver in combination for the LIS3LV02,
and put the restrictions on the I2C and SPI subdrivers
not not be combined with the old subdrivers.

This doesn't work since the IIO ST accel top-level
component selects the I2C and SPI subdrivers, resulting
in the following Kconfig noise:

warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_I2C_3AXIS
which has unmet direct dependencies (IIO && !SENSORS_LIS3_I2C
&& IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_I2C)
warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_SPI_3AXIS
which has unmet direct dependencies (IIO && !SENSORS_LIS3_SPI
&& IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_SPI)
(...)

This fixes the issue by putting the dependencies directly
in the top-level component instead, so that it never gets
to select its unselectable subcomponent.

Second round of IIO new device support, cleanups and features for the 4.11 cycle

New device support:
* lsm6dsx imu
  - new driver and bindings.
* max11100 adc
  - new driver and bindings.
* tlc4541
  - new driver
* tmp007 thermopile
  - new driver.

Core
* in kernel interfaces
  - pass through raw values if no scaling provided and a processed value is
    requested.
* trigger
  - close a race condition in acquiring trigger reference.
  - constify device_type structures.
  - rework the viio_trigger_alloc function to be much neater and easier to
  read.
  - free trigger resources correctly on some error paths. Avoids putting a
  module we don't have.

Documentation
* ABI
  - specify a unit for proximity measurements.

Cleanups and features
* ads1015
  - constify iio_info structure.
* ads7950 cleanups following merge in previous pull
  - Add device tree bindings
  - Drop the ti prefix from the module name in common with other drivers.
  - Change regulator name to vref to match datasheet and other drivers.
* ak8974
  - remove a redundant zero timeout check.
* bmi160
  - use variable names for sizeof instead of types.
* cm3605
  - mark PM functions as __maybe_unused to avoid a build warning.
* isl29028 (on it's way towards moving out of staging).
  - alignment fixes and newline improvements.
  - combine proxim_get and read_proxim for simpler code.
  - drop unused ISL29028_DEV_ATTR macro
  - move some error logging into functions to cut out repitition.
  - make error messages more consistent.
  - tidy up some brackets.
  - drop the enable flag that nothing uses.
  - only set proximity rate and ALS scale when relevant channel type is enabled.
  - runtime pm support.
* lsm6dsx
  - fix wrong values for gyro sensitivitiy.
* mag3110
  - claim direct mode during sysfs reads to avoid a race condition.
* max1363
  - export OF device table IDs as module aliases.
* max30100
  - use msleep for long uncritical delays.
* mcp4531
  - export OF device table as module aliases.
* ms5611
  - claim direct mode during sysfs reads to avoid a race condition.
* opt3001
  - export OF device table as module aliases.
* sx9500
  - claim direct mode during oversampling changes to avoid a race condition.

These stand-alone trigger drivers were using iio_trigger_put()
where they should have been using iio_trigger_free().  The
iio_trigger_put() adds a module_put which is bad since they
never did a module_get.

In the sysfs driver, module_get/put's are used as triggers are
added & removed. This extra module_put() occurs on an error path
in the probe routine (probably rare).

In the bfin-timer & interrupt trigger drivers, the module resources
are not explicitly managed, so it's doing a put on something that
was never get'd.  It occurs on the probe error path and on the
remove path (not so rare).

Tested with the sysfs trigger driver.
The bfin & interrupt drivers were build tested & inspected only.

the info field of a iio_dev structure. This field is of type const,

In iio_trigger_write_current() we find the trigger we want while
holding mutex on the list of triggers, but we don't actually do a
get on it while holding mutex.  We wait until further validations
are completed and we're sure it's the one we want.  Race condition
is that it could be freed by the time we do the get.

Solution is to grab the trigger (iio_trigger_get) as soon as we
find it while holding mutex on the list of triggers.  If later
we decide it's not the right one, put it back. (iio_trigger_put).

This patch adds runtime power management support to the isl29028 driver.
It defaults to powering off the device after two seconds of inactivity.

isl29028_chip_init_and_power_on() currently only zeros the CONFIGURE
register on the chip, which will cause the chip to turn off. This patch
also renames that function to isl29028_clear_configure_reg() since it is
