The RTL8822BE, an 802.11ac wireless network card, is now appearing in
new computers. Its driver is being placed in staging to reduce the time
that users of this new card will have access to in-kernel drivers.

This commit enables building of the new driver. For this version, all
routines are built into a single module r8822be. When this driver is
moved to the wireless tree, halmac, phydm, and rtl8822be will become
new modules.

that users of this new card will have access to in-kernel drivers.

New Realtek wireless devices have a new method for PHY control and

there is additional code required.

In the final version, this code will be a separate module; however,
it is combined with the r8822be driver to minimize the interference
with the drivers in the wireless tree.

* st_magnetometer
  - add support for the LIS2MDL with bindings.
* rockchip-saradc
  - add binding for rv1108 SoC (no driver change).
* srf08
  - add srf02 (i2c only) and srf10 support.
* stm32-timer
  - support for the STM32H7 to existing driver.

Features:
* tools
  - move over to the tools buildsystem rather than hand rolling.
  - add an install section to the build.
* ak8974
  - use serial number to add device randomness.
  - add AMI306 calibration data output.
* ccs811
  - triggered buffer support.
* srf08
  - add a device tree table as the old style i2c probing is going away,
  - add triggered buffer support
* st32-adc
  - add optional st,min-sample-time-nsecs binding to allow control of
    sampling against analog circuitry.
* stm32-timer
  - add output compare triggers.
* ti-ads1015
  - add threshold event support.
* ti-ads7950
  - Allow use on ACPI platforms including providing a default reference
    voltage as there is no way to obtain this on ACPI currently.

Cleanup and fixes:
* ad7606
  - fix an error return code in probe.
* ads1015
  - fix incorrect data rate setting update when capture in progress,
  - fix wrong scale information for the ADS1115,
  - make conversions work when CONFIG_PM is not set,
  - make sure we don't get a stale result after a runtime resume by
    ensuring we wait long enough,
  - avoid returning a false error form the buffer setup callbacks,
  - add enough wait time to get the correct conversion,
  - remove an unnecessary config register update,
  - add a helper to set conversion mode reducing repeated boilerplate,
  - use devm_iio_triggered_buffer_setup to simplify error and remove
    paths,
  - use iio_device_claim_direct_mode instead of opencoding the same.
* ak8974

* at91-sama5 adc
  - add missing Kconfig dependency.

  - explicitly request exclusive reset control as part of the reset rework
    on going throughout the kernel.

    used the non existent hardware line.
* st_pressure
  - fix drdy configuration for LPS22HB and LPS25H by dropping int2 support
    as they don't have this. Fix is unimportant as presumably no device tree
    actually used the non existent hardware line.

  - explicitly request exclusive reset control (part of reset being reworked).
* tsl2583
  - constify the i2c_device_id.
* xadc
  - coding style fixes.

Commit a53e35db ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

The ADS1015 device provides programmable comparator that can issue an
interrupt on the ALERT pin.  This change adds the iio threshold event
support for that feature.

The ADS1015 device only have a single config register which contains an
input multiplexer selection, comparator settings, and etc.  So only a
single event channel can be enabled at a time.  Also enabling both buffer
and event are prohibited for simplicity.

While the iio buffer for the ti-ads1015 driver is enabled, reading the
raw ADC channel data is restricted.  We usually use the
iio_device_claim_direct_mode()/iio_device_release_direct_mode() pair for
that.

This change consequently reverses the locking order for the driver's
private lock and indio_dev->mlock which acquired by
iio_device_claim_direct_mode() internally. But it's safe because there is
no other dependency between these locks.

The ti-ads1015 driver has eight iio voltage channels and each iio channel
can hold own scale information.

The ADS1015 device only have a single config register which contains an
input multiplexer selection, PGA and data rate settings.  So the driver
should load the correct settings when the input multiplexer selection is
changed.

However, regardless of which channlel is currently selected, changing any
iio channel's scale information immediately overwrites the current PGA
setting in the config register.

It is harmless because the correct PGA settings are reloaded just before
getting adc result anyway.  But it is unnecessary register update and
should be removed.

This driver assumes that the device is operating in the continuous
conversion mode which performs the conversion continuously.  So this driver
inserts a wait time before reading the conversion register if the
configuration is changed from a previous request.

Currently, the wait time is only the period required for a single
conversion that is calculated as the reciprocal of the sampling frequency.
However we also need to wait for the the previous conversion to complete.
Otherwise we probably get the conversion result for the previous
configuration when the sampling frequency is lower.

pm_runtime_get_sync() and pm_runtime_put_autosuspend() return 0 on
success, 1 if the device's runtime PM status was already requested status
or error code on failure.  So a positive return value doesn't indicate an
error condition.

However, any non-zero return values from buffer preenable and postdisable
callbacks are recognized as an error and this driver reuses the return
value from pm_runtime_get_sync() and pm_runtime_put_autosuspend() in
these callbacks.  This change fixes the false error detections.

This driver assumes that the device is operating in the continuous
conversion mode which performs the conversion continuously.  So this driver
doesn't insert a wait time before reading the conversion register if the
configuration is not changed from a previous request.

This assumption is broken if the device is runtime suspended and entered
a power-down state.  The forthcoming request causes reading a stale result
from the conversion register as the device is runtime resumed just before.

Fix it by adding a flag to detect that condition and insert a necessary
wait time.

The ADS1015 device have two operating modes, continuous conversion mode
and single-shot mode.  This driver assumes that the continuous conversion
mode is selected by runtime resume callback when the ADC result is
requested.

If CONFIG_PM is disabled, the device is always in the default single-shot
mode and no one begins a single conversion.  So the conversion register
doesn't contain valid ADC result.  Fix it by changing the continuous mode
in probe function.

The ti-ads1015 driver supports ADS1015 and ADS1115 devices.  The same
scale information is used for both devices in this driver, however they
have actually different values and the ADS1115's one is not correct.

These devices have the same full-scale input voltage range for each PGA
selection.  So instead of adding another hardcoded scale information,
compute a correct scale on demand from each device's resolution.

This removes the unexpected config register update and correctly load the

The config_log_add() function first calls config_log_put() with the
variable 'cld' and then jumps to label 'out_cld', which will call
the same function with the same 'cld' variable. However, at this
point, 'cld' might have been already freed by the first invocation
of config_log_put(). Even if we remove the invocation at that point,
we will still get into trouble. This is because, in the error path,
just below the label 'out_cld', we try to put 'params_cls' and
'sptlrpc_cld', which might also have been freed by config_log_put().

The point is that, config_llog_data::cld_sptlrpc and
config_llog_data::cld_params members are assigned at the beginning
of this function.

To avoid this, do not call config_log_put() inside the else block,
immediately jump to 'out_cld' instead. Moreover, remove assignments
to config_llog_data::cld_sptlrpc and config_llog_data::cld_params at
the beginning, since we already assign them below in the function
with 'cld_lock' held.

As an additional benefit, code size gets smaller.
