commit a146eccb68be161ae9eab5f3f68bb0ed7c0fbaa8 upstream.
Commit 28d1a7ac2a0d ("iio: dac: Add AD5758 support") adds the config AD5758
and the corresponding driver ad5758.c. In the Makefile, the ad5758 driver
is however included when AD5755 is selected, not when AD5758 is selected.
Probably, this was simply a mistake that happened by copy-and-paste and
forgetting to adjust the actual line. Surprisingly, no one has ever noticed
that this driver is actually only included when AD5755 is selected and that
the config AD5758 has actually no effect on the build.

commit 09d3bec7009186bdba77039df01e5834788b3f95 upstream.
The i2c_master_send() returns number of sent bytes on success,
or negative on error. The suspend/resume callbacks expect zero
on success and non-zero on error. Adapt the return value of the
i2c_master_send() to the expectation of the suspend and resume
callbacks, including proper validation of the return value.

commit c3701185ee1973845db088d8b0fc443397ab0eb2 upstream.
The CIO-DAC series of devices only supports DAC values up to 12-bit
rather than 16-bit. Trying to write a 16-bit value results in only the
lower 12 bits affecting the DAC output which is not what the user
expects. Instead, adjust the DAC write value check to reject values
larger than 12-bit so that they fail explicitly as invalid for the user.

commit 558a25f903b4af6361b7fbeea08a6446a0745653 upstream.
For reliable operation across the full range of supported
interface rates, the AD5593R needs a STOP condition between
address write, and data read (like show in the datasheet Figure 40)
so in turn i2c_smbus_read_word_swapped cannot be used.
While at it, a simple helper was added to make the code simpler.

commit 26df977a909f818b7d346b3990735513e7e0bf93 upstream.
The bindings file for this driver is defining the property as 'reg' but
the driver was reading it with the 'num' name. The bindings actually had
the 'num' property when added in
commit ea52c21268e6 ("dt-bindings: iio: dac: Add docs for AD5770R DAC")
and then changed it to 'reg' in
commit 2cf3818f18b2 ("dt-bindings: iio: dac: AD5570R fix bindings errors").
However, both these commits landed in v5.7 so the assumption is
that either 'num' is not being used or if it is, the validations were not
done.
Anyways, if someone comes back yelling about this, we might just support
both of the properties in the future. Not ideal, but that's life...

commit 558df982d4ead9cac628153d0d7b60feae05ddc8 upstream.
On success i2c_master_send() returns the number of bytes written. The
call from iio_write_channel_info(), however, expects the return value to
be zero on success.
This bug causes incorrect consumption of the sysfs buffer in
iio_write_channel_info(). When writing more than two characters to
out_voltage0_raw, the ad5446 write handler is called multiple times
causing unexpected behavior.

[ Upstream commit 97683c851f9cdbd3ea55697cbe2dcb6af4287bbd ]
The naming of the regulator is problematic. VCC is usually a supply
voltage whereas these devices have a separate VREF pin.
Secondly, the regulator core might have provided a stub regulator if
a real regulator wasn't provided. That would in turn have failed to
provide a voltage when queried. So reality was that there was no way
to use the internal reference.
In order to avoid breaking any dts out in the wild, make sure to fallback
to the original vcc naming if vref is not available.

The power-down mask of the ad5504 is actually a power-up mask. Meaning if
a bit is set the corresponding channel is powered up and if it is not set
the channel is powered down.
The driver currently has this the wrong way around, resulting in the
channel being powered up when requested to be powered down and vice versa.

Since there was a recently discovered issue with these locks, it probably
makes sense to cleanup the code a bit, to prevent it from being used as an
example/reference.
This change moves the lock only where it is explicitly needed to protect
resources from potential concurrent accesses.
It also reworks the switch statements to do direct returns vs caching the
return value on a variable.

This enables use of ACPI PRP0001 and removes an antipattern I am
trying to stop people copying in IIO.
This particular case is more complex than most because it allowed
probing via sysfs with out a fwnode but would presumably always
have then failed. Now the code will assume that properties are
the defaults if not specified or the firmware node is not present.
This relaxation of the constraints should not break any existing
cases and may enable some new ones.

These result in a very small reduction in driver size, but at the
cost of more complex build and slightly harder to read code.
In the case of of_match_ptr it also prevents use of PRP0001
ACPI based identification. In this particular case we have
a valid ACPI/PNP ID that I am assuming was issued by Analog
Devices. That should be used in preference to PRP0001 but doesn't
mean we should prevent that route.

As part of the general cleanup of indio_dev->mlock, this change replaces
it with a local lock on the device's state from potential concurrent write
accesses from userspace. The write operation requires an SPI write, then
toggling of a GPIO, so the lock aims to protect the sanity of the entire
sequence of operation.
This is part of a bigger cleanup.

There are 2 exit paths where the lock isn't held, but try to unlock the
mutex when exiting. In these places we should just return from the
function.
A neater approach would be to cleanup the ad5592r_read_raw(), but that
would make this patch more difficult to backport to stable versions.

Some new devices, but particularly good this time is the core rework coming
from Alexandru. Some of this has been in Analog's tree a long time, but other
parts are motivated by closing down common mistakes in new drivers.
Changes since first try at this pull request:
* Add missed patch to actually remove iio_priv_to_dev and as a result
also drop a few ingenic patches that need to be updated to take this
into account.
* Fix an ordering issue int he pollfunc attach in the core rework.
New device support
* qcom pmic7 adc
- New driver using common qcom-vadc library. Some associated cleanups and
refactors.
* invensense icm42600
- New driver supporting icm42600, icm42602, icm42605 and icm42622 via i2c
or spi. These are all 6 axis IMUs with gyro and accelerometers.
Driver supports buffered modes using the hardware fifo and interpolation
for accurate timestamps.
* sensirion scd30
- New driver for this carbon dioxide sensor including i2c and serial
interfaces + bindings.
Features
* ak8975
- Add reset gpio support.
* bma400
- Support SPI.
* bmc150
- Document and add support for bmc156b and bmm150b, tidy up _magn endings.
* bmi160
- Regulator and mount matrix support.
* mxc4005
- Add ID for mxc6655
* rockchip-saradc
- Triggered buffer support.
DT bindings
* qcom spmi-vadc converted to yaml + pmic7 bindings
* ak8975 tidy up and convert to yaml + add reset-gpio binding
* ingenic-adc -convert to yaml.
Core rework all carried through by Alexandru Ardelean.
* Assign parent device in the core rather than every driver. A few devices
need to provide specific non standard parents, so there is support for
overriding.
* Start to take parts of struct iio_dev opaque to the drivers.
This will be a long term job, but should reduce the number of drivers
we get that use parts that are currently only 'internal' by documentation.
* Move attach and detach of pollfunc to the core. Every triggered buffer
using driver had to do the same thing, so lets do it in the core. The
hard part here was getting all the drivers into canonical form so there
would be no functional changes in this final patch. That's taken quite
a lot of work over last couple of cycles!
Cleanups and minor fixes.
* docs
- Improve IIO_CONCENTRATION channel type description in ABI docs.
- Drop doubled word cases.
- Http to Https conversion.
* core
- Make iio_device_get_drvdata take a const struct iio_dev * avoiding some
nasty casts.
* ADCs
- Drop lots of users of of_match_ptr macro, includes of mod_devicetable.h
and CONFIG_OF protections. These prevent use of ACPI PRP0001 with these
drivers and get coppied into lots of new drivers.
* ad5380
- Constify iio_chan_spec_ext_info
* ad5592r
- Constify iio_chan_spec_ext_info
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* ad8366
- Make gpio optional as doesn't matter if its there or not.
* adis16480
- Use irq types instead of the flags.
* atlas-ezo-sensor
- Minimize scope of ret variable.
* at91-adc
- Add COMPILE_TEST dependency to driver to improve build coverage.
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* at91-sama5d2
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
- Drop Ludovic as a co-maintaienr.
* cros_ec
- Reapply the range after resume.
- Add a read only frequency entry for legacy version.
- Typo fixes
* hts221
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* inv_mpu
- Drop double check on ACPI companion device.
* iqs621
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* iqs624
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* max11100
- Constify iio_chan_spec
* mmc35240
- Constify reg_default
* rockchip-saradc
- Move to managed allocators for everything in probe.
- Use more distinctive prefix for channel macros.
* stk3310
- Constify regmap_config.
* stm32-adc
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* stm32-dfsdm-adc
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)

First set of new device support, cleanups and features for IIO in the 5.9 cycle
Some new devices, but particularly good this time is the core rework coming
from Alexandru. Some of this has been in Analog's tree a long time, but other
parts are motivated by closing down common mistakes in new drivers.
Changes since first try at this pull request:
* Add missed patch to actually remove iio_priv_to_dev and as a result
also drop a few ingenic patches that need to be updated to take this
into account.
* Fix an ordering issue int he pollfunc attach in the core rework.
New device support
* qcom pmic7 adc
- New driver using common qcom-vadc library. Some associated cleanups and
refactors.
* invensense icm42600
- New driver supporting icm42600, icm42602, icm42605 and icm42622 via i2c
or spi. These are all 6 axis IMUs with gyro and accelerometers.
Driver supports buffered modes using the hardware fifo and interpolation
for accurate timestamps.
* sensirion scd30
- New driver for this carbon dioxide sensor including i2c and serial
interfaces + bindings.
Features
* ak8975
- Add reset gpio support.
* bma400
- Support SPI.
* bmc150
- Document and add support for bmc156b and bmm150b, tidy up _magn endings.
* bmi160
- Regulator and mount matrix support.
* mxc4005
- Add ID for mxc6655
* rockchip-saradc
- Triggered buffer support.
DT bindings
* qcom spmi-vadc converted to yaml + pmic7 bindings
* ak8975 tidy up and convert to yaml + add reset-gpio binding
* ingenic-adc -convert to yaml.
Core rework all carried through by Alexandru Ardelean.
* Assign parent device in the core rather than every driver. A few devices
need to provide specific non standard parents, so there is support for
overriding.
* Start to take parts of struct iio_dev opaque to the drivers.
This will be a long term job, but should reduce the number of drivers
we get that use parts that are currently only 'internal' by documentation.
* Move attach and detach of pollfunc to the core. Every triggered buffer
using driver had to do the same thing, so lets do it in the core. The
hard part here was getting all the drivers into canonical form so there
would be no functional changes in this final patch. That's taken quite
a lot of work over last couple of cycles!
Cleanups and minor fixes.
* docs
- Improve IIO_CONCENTRATION channel type description in ABI docs.
- Drop doubled word cases.
- Http to Https conversion.
* core
- Make iio_device_get_drvdata take a const struct iio_dev * avoiding some
nasty casts.
* ADCs
- Drop lots of users of of_match_ptr macro, includes of mod_devicetable.h
and CONFIG_OF protections. These prevent use of ACPI PRP0001 with these
drivers and get coppied into lots of new drivers.
* ad5380
- Constify iio_chan_spec_ext_info
* ad5592r
- Constify iio_chan_spec_ext_info
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* ad8366
- Make gpio optional as doesn't matter if its there or not.
* adis16480
- Use irq types instead of the flags.
* atlas-ezo-sensor
- Minimize scope of ret variable.
* at91-adc
- Add COMPILE_TEST dependency to driver to improve build coverage.
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* at91-sama5d2
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
- Drop Ludovic as a co-maintaienr.
* cros_ec
- Reapply the range after resume.
- Add a read only frequency entry for legacy version.
- Typo fixes
* hts221
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* inv_mpu
- Drop double check on ACPI companion device.
* iqs621
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* iqs624
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* max11100
- Constify iio_chan_spec
* mmc35240
- Constify reg_default
* rockchip-saradc
- Move to managed allocators for everything in probe.
- Use more distinctive prefix for channel macros.
* stk3310
- Constify regmap_config.
* stm32-adc
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* stm32-dfsdm-adc
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* ti-am335x
- Use managed allocations where straight forward in probe function.
* tsl2563
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.
