c1404d1b65 iio: adc: mt6370: Add MediaTek MT6370 support
MediaTek MT6370 is a SubPMIC consisting of a single cell battery charger
with ADC monitoring, RGB LEDs, dual channel flashlight, WLED backlight
driver, display bias voltage supply, one general purpose LDO, and the
USB Type-C & PD controller complies with the latest USB Type-C and PD
standards.

Add support for the MT6370 ADC driver for system monitoring, including
charger current, voltage, and temperature.

a44ef7c460 iio: adc: add max11410 adc driver
Adding support for max11410 24-bit, 1.9ksps delta-sigma adc which
has 3 differential reference and 10 differential channel inputs.
Inputs and references can be buffered internally. Inputs can also
be amplified with internal PGA.

Device has four digital filter modes: FIR50/60, FIR50, FIR60 and SINC4.
FIR 50Hz and 60Hz rejections can be enabled/disabled separately.
Digital filter selection affects sampling frequency range so driver
has to consider the configured filter when configuring sampling frequency.

4e15cad8db iio: adc: vf610_adc: vf610_adc: do not use internal iio_dev lock
In order to drop the internal lock usage we needed two different things:

1) The first place where 'mlock' was being used was a typical case where
iio_device_claim_direct_mode() fits perfectly.
2) In the second case, it was being used to prevent concurrent accesses
to the device and shared data but nothing was being enforced with
regards to buffering (i.e, there was nothing preventing from changing
the conversion mode while buffering). Hence, in this case, a new lock
was introduced in the state structure.

Note that the goal is not to introduce any functional change and that is
the reason why a new lock was introduced to guarantee 2).

While at it, properly include "mutex.h" for mutex related APIs.

8f347c565d iio: adc: ad799x: do not use internal iio_dev lock
'mlock' was being grabbed when setting the device frequency. In order to
not introduce any functional change a new lock is added. With that in
mind, the lock also needs to be grabbed in the places where 'mlock' is
since it was also being used to protect st->config against the current
device state.

On the other places the lock was being used, we can just drop
it since we are only doing one i2c bus read/write which is already
safe.

3f4033a811 iio: filter: admv8818: close potential out-of-bounds read in __admv8818_read_[h|l]pf_freq()
ADMV8818_SW_IN_WR0_MSK and ADMV8818_SW_OUT_WR0_MSK have 3 bits,
which means a length of 8, but freq_range_hpf and freq_range_lpf
array size is 4, may end up reading 4 elements beyond the end of
those arrays.

Check value first before access freq_range_hpf and freq_range_lpf
to harden against the hardware allowing out of range values.

4e61514036 iio: temperature: mlx90632 Change return value of sensor measurement channel
The current EINVAL value is more applicable to embedded library, where
user can actually put the fixed value to the sensor. In case of the
driver if the value of the channel is invalid it is better in inform
userspace that Channel was out of range as that implies more to internal
driver error than invalid input. It also makes for easier debugging of
where the error comes from during the development.

2aebc223fc iio: temperature: mlx90632 Add runtime powermanagement modes
The sensor can operate in lower power modes and even make measurements when
in those lower powered modes. The decision was taken that if measurement
is not requested within 2 seconds the sensor will remain in SLEEP_STEP
power mode, where measurements are triggered on request with setting the
start of measurement bit (SOB). In this mode the measurements are taking
a bit longer because we need to start it and complete it. Currently, in
continuous mode we read ready data and this mode is activated if sensor
measurement is requested within 2 seconds. The suspend timeout is
increased to 6 seconds (instead of 3 before), because that enables more
measurements in lower power mode (SLEEP_STEP), with the lowest refresh
rate (2 seconds).

This change actually makes sure we cannot do a single conversion while

enabled.

Pull random number generator fix from Jason Donenfeld:
 "One fix from Jean-Philippe Brucker, addressing a regression in which
  early boot code on ARM64 would use the non-_early variant of the
  arch_get_random family of functions, resulting in the architectural
  random number generator appearing unavailable during that early phase
  of boot.

  The fix simply changes arch_get_random*() to arch_get_random*_early().

  This distinction between these two functions is a bit of an old wart
  I'm not a fan of, and for 6.2 I'll see if I can make obsolete the
  _early variant, so that one function does the right thing in all
  contexts without overhead"
