Greg Kroah-Hartman 74eb9c06b1 Second set of new device support, cleanups and features for IIO in the 5.4 cycle
Revised pull request to fix up a missing Signed-off-by and roll in
 a fix in the lsm9ds1 support after I broke it when applying.
 Revised again because the fix changed a hash meaning a fix
 that previously followed it now had the wrong fixes tag.
 
 A few fixes in here that could have gone a faster path but aren't quite
 worth the rush for 5.3.

Martin Kepplinger 52f4b1f196 iio: imu: st_lsm6dsx: add support for accel/gyro unit of lsm9ds1
The LSM9DS1's accelerometer / gyroscope unit and it's magnetometer (separately
supported in iio/magnetometer/st_magn*) are located on a separate i2c addresses
on the bus.

For the datasheet, see https://www.st.com/resource/en/datasheet/lsm9ds1.pdf

Treat it just like the LSM6* devices and, despite it's name, hook it up
to the st_lsm6dsx driver, using it's basic functionality.

accelerometer and gyroscope are not independently clocked. It runs at the gyro
frequencies if both are enabled, see chapter 7.12 of the datasheet.
We could have handled this as a single IIO device but we have split
it up to be more consistent with the other more flexible devices.

Despite supporting and testing the LSM9DS1, we call the gyro channels
iio_chan_spec struct "st_lsm6ds0_gyro_channels" because the register
description is equal. This suggests that supporting LSM6DS0 should be
trivial to do.

Enric Balletbo i Serra 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

Stefan Popa d2a415c86c iio: adc: ad7606: Add support for AD7606B ADC
The AD7606B is a 16-bit ADC that supports simultaneous sampling of 8
channels. It is pin compatible to AD7606, but adds extra modes by
writing to the register map.

The AD7606B can be configured to work in software mode by setting all
oversampling pins to high. This mode is selected by default.
The oversampling ratio is configured from the OS_MODE register (address
0x08) with the addition of OS=128 and OS=256 that were not available in
hardware mode.

The device is configured to output data on a single spi channel, but this
configuration must be done right after restart. That is why the delay was
removed for devices which doesn't require it.

Moreover, in software mode, the range gpio has no longer its function.
Instead, the scale can be configured individually for each channel from
the RANGE_CH registers (address 0x03 to 0x06). Besides the already
supported ±10 V and ±5 V ranges, software mode can also accommodate the
±2.5 V range.

On Spreadtrum platform, the headphone will read one ADC channel multiple
times to identify the headphone type, and the headphone identification is
sensitive of the ADC reading time. And we found it will take longer time
to reading ADC data by using interrupt mode comparing with the polling
mode, thus we should change to polling mode to improve the efficiency
of reading data, which can identify the headphone type successfully.

Unsigned is not less than zero.
```

The types of `val` && `val2` are obtained from the IIO `write_raw` hook, so
userspace can provide negative values, which can cause weird behavior after
conversion to unsigned.

This patch changes the sign of variable `t` so that -EINVAL will be
returned for negative values as well.

The max9611 driver reads the die temperature at probe time to validate
the communication channel. Use the actual read value to perform the test
instead of the read function return value, which was mistakenly used so
far.

The temperature reading test was only successful because the 0 return
value is in the range of supported temperatures.

Martin Kepplinger 48cceecfa7 iio: imu: st_lsm6dsx: make IIO_CHAN_INFO_SCALE shared by type
in_accel_x_scale, in_accel_y_scale and in_accel_z_scale are always
the same. The scale is still defined to be in "info_mask_separate".

Userspace (iio-sensor-proxy and others) is not used to that and only
looks for "in_accel_scale" for the scaling factor to apply.

Change IIO_CHAN_INFO_SCALE from being separate in all channel to be
shared by type.

This removes in_accel_x_scale, in_accel_y_scale and in_accel_z_scale and
makes available in_accel_scale.

This is an ABI change, but hopefully in the 'no one will notice'
category.  The cleanup in interface is worth the small risk that
there is a custom script out there somewhere that this will break.

Use devm_add_action_or_reset to call tsl2772_chip_off
when the device is removed.
This also fixes the issue that the chip is turned off
before the device is unregistered.

Not marked for stable as fairly hard to hit the bug and
this is in the middle of a set making other cleanups
to the driver.  Hence will probably need explicit backporting.

This patch is trying to cleanup for good the buffers operation functions.
There is no need of using preenable, all can be done into

already done in accel driver.
Finally also rename the goto label using operation to perform and not
where it fails.

Not stable material as not fixing a 'bug' but rather bringing the

Also, in order to support multiple devices in software mode, the spi

Alexandru Ardelean db6ed4d23d iio: imu: Add support for the ADIS16460 IMU
The ADIS16460 device is a complete inertial system that includes a triaxial
gyroscope and a triaxial accelerometer. It's more simplified design than
that of the ADIS16480, and does not offer the triaxial magnetometers &
pressure sensors. It does also have a temperature sensor (like the
ADIS16480).
Since it is part of the ADIS16XXX family, it re-uses parts of the ADIS
library.

Naturally, the register map is different and much more simplified than the
ADIS16480 subfamily, so it cannot be integrated into that driver. A major
difference is that the registers are not paged.

One thing that is particularly special about it, is that it requires a
higher delay between CS changes (i.e. when CS goes up, the spec recommends
that it be brought down after a minimum of 16 uS).
Other ADIS chips require (via spec) a minimum of 2 uS between CS changes.
The kernel's 10 uS default should be fine for those other chips; they
haven't been tested with lower CS change delays yet.

The support for this functionality in ADIS16460 requires an addition to the

subsystem.

On stm32h7 and stm32mp1, the ADC inputs are multiplexed with analog
switches which have reduced performances when their supply is below 2.7V
(vdda by default):
- 3.3V embedded booster can be used, to get full ADC performances
  (increases power consumption).
- vdd supply can be selected if above 2.7V by setting ANASWVDD syscfg bit,

Maarten ter Huurne 5a304e1a4e IIO: Ingenic JZ47xx: Set clock divider on probe
The SADC component can run at up to 8 MHz on JZ4725B, but is fed
a 12 MHz input clock (EXT). Divide it by two to get 6 MHz, then
set up another divider to match, to produce a 10us clock.

If the clock dividers are left on their power-on defaults (a divider
of 1), the SADC mostly works, but will occasionally produce erroneous
readings. This led to button presses being detected out of nowhere on
the RS90 every few minutes. With this change, no ghost button presses
were logged in almost a day worth of testing.

The ADCLK register for configuring clock dividers doesn't exist on
JZ4740, so avoid writing it there.

A function has been introduced rather than a flag because there is a lot
of variation between the ADCLK registers on JZ47xx SoCs, both in
the internal layout of the register and in the frequency range
supported by the SADC. So this solution should make it easier
to add support for other JZ47xx SoCs later.

Linus Torvalds f632a8170a Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1
 
 It's a lot of different patches, all across the tree due to some api
 changes and lots of debugfs cleanups.  Because of this, there is going
 to be some merge issues with your tree at the moment, I'll follow up
 with the expected resolutions to make it easier for you.
 
 Other than the debugfs cleanups, in this set of changes we have:
 	- bus iteration function cleanups (will cause build warnings
 	  with s390 and coresight drivers in your tree)
 	- scripts/get_abi.pl tool to display and parse Documentation/ABI
 	  entries in a simple way
 	- cleanups to Documenatation/ABI/ entries to make them parse
 	  easier due to typos and other minor things
 	- default_attrs use for some ktype users
 	- driver model documentation file conversions to .rst
 	- compressed firmware file loading
 	- deferred probe fixes
 
 All of these have been in linux-next for a while, with a bunch of merge
 issues that Stephen has been patient with me for.  Other than the merge
 issues, functionality is working properly in linux-next :)

Greg Kroah-Hartman c55cc97a25 Second set of IIO device support, features, cleanups and minor fixes for 5.3.
A few bits for the counters subsystem mixed in here as well.
 There are some late breaking fixes as well, which aren't so urgent
 they can't wait for the merge window.
 
 New Device Support
 * adf4371
   - New driver + bindings.
   - Support the adf4372 PLL. Mostly ID and bindings.
 * ad8366 (note includes rework of driver needed to allow support for these).
   - Support the ADL5240 variable gain amplifier (VGA).
   - Support the ADA4961 digital gain amplifier (DGA).
 * dps310
   - New driver, in several parts from different authors for this temp
     and pressure sensor.
   - Includes errata workaround for a temperature reading issue.
 * stk3310
   - Support the stk3335, mostly ID.
 
 Features and cleanups
 * core
   - drop error handling on debugfs registration.
   - harden by making sure we don't overrun iio_chan_info_postfix.
 * docs
   - convert remaining docs to rst. At somepoint we'll fit these few
     into the main IIO docs.
   - improve sampling_frequency_available docs but explaining the
     range form.
 * ad_sigma_delta
   - Drop a pointless goto.
 * ad2s1210
   - Drop pointless platform data null check seeing as we don't actually
     use platform data anymore.
 * ad7124
   - Relax limitation on channel numbers to allow pseudo different channels.
   - Support control of whether the input is buffered via DT.
   - Use dynamic allocation for channel configuration to make it easier
     to support new devices.
   - YAML binding conversion.
 * ad7150
   - Comment tidy up.
   - Consistent and simple if (ret) handling of i2c errors.
   - FIELD_GET and GENMASK.
   - Ternary rather than !!(condition) for readability.
   - Use macros to avoid repetition of channel definitions.
 * ad7606
   - Add software channel config (rather that pin controlled)
   - Refactor to simplify addition of new part in future.
 * ad7746
   - of_deivce_id table.
 * ad7780
   - MAINTAINERS entry
   - YAML DT bindings.
 * ad8366
   - Stop using core mlock in favour of well scoped local lock.
   - SPDX + copyright date update.
 * ad9834
   - of_device_id table
 * adf4371
   - Add support for output stage muting before lock on has occured.
 * adis library
   - MAINTAINERS entry to reflect that this now Alexandru's problem ;)
 * adis162xx:
   - Fix a slightly incorrect set of comments and print statements on
     minimum supported voltage.
 * adis16203
   - of_device_id table.
 * adis16240
   - Add of_device_id table (in two parts as first patch only used it for
     MODULE_DEVICE_TABLE.)
 * adt7316-spi
   - of_device_id table
 * adxl372
   - YAML DT binding conversion.
   - Cleanup use of buffer callback functions (precursor to core rework).
 * bh1710
   - Simplify getting the i2c adapter from the client.
 * dht11
   - Mote to newer GPIO consumer interface.
 * kxcjk-1013.c
   - Add binding for sensor in display of some ultrabooks after userspace
     tools updated for it not be a problem to report two similar sensors.
 * imx7d
   - drop unused variables.
   - white space
   - define instead of variable for clock frequency that is fixed.
   - drop pointless error message.
 * messon_saradc
   - SPDX
 * sps30
   - MAINTAINERS entry
   - YAML binding conversion.
 * st_accel
   - 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.

Merge tag 'iio-for-5.3b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

Second set of IIO device support, features, cleanups and minor fixes for 5.3.

A few bits for the counters subsystem mixed in here as well.
There are some late breaking fixes as well, which aren't so urgent
they can't wait for the merge window.

New Device Support
* adf4371
  - New driver + bindings.
  - Support the adf4372 PLL. Mostly ID and bindings.
* ad8366 (note includes rework of driver needed to allow support for these).
  - Support the ADL5240 variable gain amplifier (VGA).
  - Support the ADA4961 digital gain amplifier (DGA).
* dps310
  - New driver, in several parts from different authors for this temp
    and pressure sensor.
  - Includes errata workaround for a temperature reading issue.
* stk3310
  - Support the stk3335, mostly ID.

Features and cleanups
* core
  - drop error handling on debugfs registration.
  - harden by making sure we don't overrun iio_chan_info_postfix.
* docs
  - convert remaining docs to rst. At somepoint we'll fit these few
    into the main IIO docs.
  - improve sampling_frequency_available docs but explaining the
    range form.
* ad_sigma_delta
  - Drop a pointless goto.
* ad2s1210
  - Drop pointless platform data null check seeing as we don't actually
    use platform data anymore.
* ad7124
  - Relax limitation on channel numbers to allow pseudo different channels.
  - Support control of whether the input is buffered via DT.
  - Use dynamic allocation for channel configuration to make it easier
    to support new devices.
  - YAML binding conversion.
* ad7150
  - Comment tidy up.
  - Consistent and simple if (ret) handling of i2c errors.
  - FIELD_GET and GENMASK.
  - Ternary rather than !!(condition) for readability.
  - Use macros to avoid repetition of channel definitions.
* ad7606
  - Add software channel config (rather that pin controlled)
  - Refactor to simplify addition of new part in future.
* ad7746
  - of_deivce_id table.
* ad7780
  - MAINTAINERS entry
  - YAML DT bindings.
* ad8366
  - Stop using core mlock in favour of well scoped local lock.
  - SPDX + copyright date update.
* ad9834
  - of_device_id table
* adf4371
  - Add support for output stage muting before lock on has occured.
* adis library
  - MAINTAINERS entry to reflect that this now Alexandru's problem ;)
* adis162xx:
  - Fix a slightly incorrect set of comments and print statements on
    minimum supported voltage.
* adis16203
  - of_device_id table.
* adis16240
  - Add of_device_id table (in two parts as first patch only used it for
    MODULE_DEVICE_TABLE.)
* adt7316-spi
  - of_device_id table
* adxl372
  - YAML DT binding conversion.
  - Cleanup use of buffer callback functions (precursor to core rework).
* bh1710
  - Simplify getting the i2c adapter from the client.
* dht11
  - Mote to newer GPIO consumer interface.
* kxcjk-1013.c
  - Add binding for sensor in display of some ultrabooks after userspace
    tools updated for it not be a problem to report two similar sensors.
* imx7d
  - drop unused variables.
  - white space
  - define instead of variable for clock frequency that is fixed.
  - drop pointless error message.
* messon_saradc
  - SPDX
* sps30
  - MAINTAINERS entry
  - YAML binding conversion.
* st_accel
  - 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.

Stefan Popa def914a4c3 iio: frequency: adf4371: Add support for output stage mute
Another feature of the ADF4371/ADF4372 is that the supply current to the
RF8P and RF8N output stage can shut down until the ADF4371 achieves lock
as measured by the digital lock detect circuitry. The mute to lock
detect bit (MUTE_LD) in REG25 enables this function.

The ADF4372 is part of the same family with ADF4371, the main difference
is that it has only 3 channels instead of 4, as the frequency quadrupler
is missing. As a result, the ADF4372 allows frequencies from 62.5 MHz to
16 GHz to be generated.

Mircea Caprioru 1478a388f4 iio: adc: ad7124: Shift to dynamic allocation for channel configuration
This patch changes the channel configuration member of the device
structure from a fixed size array to a dynamic allocated one with a size
equal to the number of channels specified in the device tree. This will
ensure a more flexibility for compatible devices.

Ex. ad7124-4 - can have 4 differential or 8 pseudo-differential channels
ad7124-8 - can have 8 differential or 16 pseudo-differential channels

Also the device can suspport any other combination of differential and
pseudo-differential channels base on the physical number of inputs
available.

Mircea Caprioru 0eaecea6e4 iio: adc: ad7124: Add buffered input support
This patch adds the option to enable the buffered mode for positive and
negative inputs. Each option can be enabled independently.

In buffered mode, the input channel feeds into a high impedance input stage
of the buffer amplifier. Therefore, the input can tolerate significant
source impedances and is tailored for direct connection to external
resistive type sensors such as strain gages or RTDs.

The driver limits the user to use only 4/8 differential inputs, but this
device has the option to use pseudo-differential channels. This will
increase the number of channels to be equal with the number of inputs so 8
channels for ad7124-4 and 16 for ad7124-8.

Also, when an error is reported the printed value is incorrect.

Suzuki K Poulose 418e3ea157 bus_find_device: Unify the match callback with class_find_device
There is an arbitrary difference between the prototypes of
bus_find_device() and class_find_device() preventing their callers
from passing the same pair of data and match() arguments to both of
them, which is the const qualifier used in the prototype of
class_find_device().  If that qualifier is also used in the
bus_find_device() prototype, it will be possible to pass the same
match() callback function to both bus_find_device() and
class_find_device(), which will allow some optimizations to be made in
order to avoid code duplication going forward.  Also with that, constify
the "data" parameter as it is passed as a const to the match function.

For this reason, change the prototype of bus_find_device() to match
the prototype of class_find_device() and adjust its callers to use the
const qualifier in accordance with the new prototype of it.

The use of fast mode allows to get a larger set of solution
for filter parameters. This can be useful to reach a better
output sample resolution, when fast mode can be used.

Fast mode is selected at startup if it is relevant.
The startup is performed in postenable callback context,
where there are too tight time constraints for filter parameters
computation. For this reason both fast and non fast filter parameters
are pre-computed previously.

The SPI gain amplifiers are simple devices, with 1 or 2 channels, to which
are read-from/written-to.

The gain computation in ad8366_write_raw() has been updated to compute gain
in dB for negative values.

This driver will be extended to support other chips as well.
To do that, this rework handles the AD8366 device as a special-case (via
switch-statements). This will make things easier when adding new chips.

Stefan Popa 7f699bd149 iio: frequency: adf4371: Add support for ADF4371 PLL
The ADF4371 is a frequency synthesizer with an integrated voltage
controlled oscillator (VCO) for phase-locked loops (PLLs). The ADF4371
has an integrated VCO with a fundamental output frequency ranging from
4000 MHz to 8000 MHz. In addition, the VCO frequency is connected to
divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allows the user to
generate radio frequency (RF) output frequencies as low as 62.5 MHz at
RF8x. A frequency multiplier at RF16x generates from 8 GHz to 16 GHz. A
frequency quadrupler generates frequencies from 16 GHz to 32 GHz at RF32x.
RFAUX8x duplicates the frequency range of RF8x or permits direct access to
the VCO output.

The driver takes the reference input frequency from the device tree and
uses it to calculate and maximize the PFD frequency (frequency of the phase
frequency detector). The PFD frequency is further used to calculate the
timeouts: synthesizer lock, VCO band selection, automatic level
calibration (ALC) and PLL settling time.

This initial driver exposes the attributes for setting the frequency and
enabling/disabling the different adf4371 channels.

Linus Torvalds 2f4c533499 SPDX update for 5.2-rc3, round 1
Here is another set of reviewed patches that adds SPDX tags to different
 kernel files, based on a set of rules that are being used to parse the
 comments to try to determine that the license of the file is
 "GPL-2.0-or-later" or "GPL-2.0-only".  Only the "obvious" versions of
 these matches are included here, a number of "non-obvious" variants of
 text have been found but those have been postponed for later review and
 analysis.
 
 There is also a patch in here to add the proper SPDX header to a bunch
 of Kbuild files that we have missed in the past due to new files being
 added and forgetting that Kbuild uses two different file names for
 Makefiles.  This issue was reported by the Kbuild maintainer.
 
 These patches have been out for review on the linux-spdx@vger mailing
 list, and while they were created by automatic tools, they were
 hand-verified by a bunch of different people, all whom names are on the
 patches are reviewers.

Register EE_VERSION contains mixture of calibration information and DSP
version. So far, because calibrations were definite, the driver
compatibility depended on whole contents, but in the newer production
process the calibration part changes. Because of that, value in EE_VERSION
will be changed and to avoid that calibration value is same as DSP version
the MSB in calibration part was fixed to 1.
That means existing calibrations (medical and consumer) will now have
hex values (bits 8 to 15) of 83 and 84 respectively. Driver compatibility
should be based only on DSP version part of the EE_VERSION (bits 0 to 7)
register.

Sean Nyekjaer e6d1229831 iio: adc: ti-ads8688: fix timestamp is not updated in buffer
When using the hrtimer iio trigger timestamp isn't updated.
If we use iio_get_time_ns it is updated correctly.

Ruslan Babayev 60f2208699 iio: dac: ds4422/ds4424 fix chip verification
The ds4424_get_value function takes channel number as it's 3rd
argument and translates it internally into I2C address using
DS4424_DAC_ADDR macro. The caller ds4424_verify_chip was passing an
already translated I2C address as its last argument.

Ruslan Babayev a2d2010d95 iio: dac: ds4422/ds4424 drop of_node check
The driver doesn't actually rely on any DT properties. Removing this
check makes it usable on ACPI based platforms.

Philippe Schenker e813dde6f8 iio: stmpe-adc: Use wait_for_completion_timeout
Use wait_for_completion_timeout instead of
wait_for_completion_interuptible_timeout.

The interruptible variant gets constantly interrupted if a user
program is compiled with the -pg option.
The killable variant was not used due to the fact that a second
program, reading on this device, that gets killed is then also killing
that wait.
