This comment was in place in the original drafts of these drivers
when the remove function did a whole lot of work: flushed queues,
unregistered interrupts, uninitialized rings, unconfigured rings,
and a few kfree's.
The remove functions have since been reduced to unregistering and
stopping the device. This is the inverse of what was done during
probe and is correct. Time to remove the comment.

The adc driver uses of_iomap() which doesn't request the resource and
isn't device managed so error handling is needed. of_iomap() is mainly
used in cases where there is no driver or struct device so a switch to
devm_ functions is required.
This patch switches to use devm_ioremap_resource() instead which
automatically requests the resource and is freed when the driver
detaches.
Removed the error handling to unmap I/O registers i.e.
iounmap() in probe and remove functions of this driver and
consequently removed an unnecessary label.

Good to see several new contributors in this set - and more generally a
number of new 'faces' over this whole cycle.
Staging movements
* hmc5843
- out of staging.
* periodic RTC trigger
- driver dropped. This is an ancient driver (brings back some memories ;)
that was always somewhat of a bodge. Originally there was a driver that
never went into mainline that supported large numbers of periodict timers
on the PXA270 via this route. Discussions to have a generic periodic
timer subsystem never went anywhere. At the time RTC periodic
interrupts were real - now they are emulated using high resolution
timers so with the HRT driver this has become pointless.
New device support
* mpu6050 driver
- Add support for the mpu6500.
* TI tpl0102 potentiometer
- new driver.
* Vybrid SoC DAC
- new driver. The ADC on this SoC has been supported for a while, this
adds a separate driver for the DAC.
New Features
* hmc5844
- Attributes to configure the bias current (typically part of a self test)
This could be done before via a somewhat obscure custom interface.
This at least makes it easy to tell what is going on.
- Document all custom attributes.
* mpu6050
- Add support for calibration offset control and readback.
* ms5611
- power regulator support. This is always one that gets added the
first time someone has a board that needs it. Here it was needed,
hence it was added.
Cleanups / minor fixes
* tree wide
- clean up all the myriad different return values in response to a
failure of i2c_check_functionality. After discussions everyone seemed
happy wiht -EOPNOTSUPP which seems to describe the situation well.
I encouraged a tree wide cleanup to set a good example in future for
this.
* core
- Typos in the iio_event_spec documentation in iio.h
* afe4403
- select REGMAP_SPI to avoid dependency issues
- mark suspend/resume as __maybe_unused to avoid warnings
* afe4404
- mark suspend/resume as __maybe_unused to avoid warnings
* atlas-ph-sensor
- switch the regmap cache type from linear to rbtree to gain reading of
registers on initial startup. It's not immediately obvious, but
regmap flat is meant for high performances cases so doesn't read these
registers.
- use regmap_bulk_read in one case where it was using
i2c_smbus_read_i2c_block_data directly (unlike everything else that was
through regmap).
* ina2xx
- stype cleanups (lots of them!)
* isl29018
- Get the struct device back from regmap rather than storing another
copy of it in the private data. This cleanup makes sense in a number
of other drivers so patches may well follow.
* mpu6050
- style cleanups (lots of them!)
- improved return value handling
- use usleep_range to avoid the usual issues with very short msleeps.
- add some missing documentation.
* ms5611
- use the probed device name for the device rather than the driver name.
- select IIO_BUFFER to avoid dependency issues
* palmas
- drop IRQF_EARLY_RESUME as no longer needed after genirq changes.

With the recently introduced hrtimer based trigger we have a fully
functional replacement for the RTC timer trigger that is more flexible and
has a better interface to instantiate and manage the trigger instances. The
RTC trigger timer could only be instantiated using platform devices which
makes it unsuitable for modern devicetree based platforms, while the
hrtimer trigger has a configfs based interface that allows creating and
deletion of triggers at runtime.
In addition since a few years the periodic RTC timer is internally always
emulated using a hrtimer using the hrtimer interface directly will yield
the same timing precision. So using the RTC timer won't have any advantages
on this front either.
There is also no evidence that the periodic RTC trigger is currently
actually being used on any system. So considering all this remove the
driver. Also remove the related item from the TODO list.

Change static attribute meas_conf for bias current configuration
to channel attribute in_magn_meas_conf and also add
in_magn_meas_conf_available attribute to view available configurations.
This patch solves functionality bug: driver was using same function
hmc5843_set_measurement_configuration for setting bias current config
for all device types but the function was returning -EINVAL for any
setting >= 0x03 although, for sensor HMC5983, value 3 is valid.
API for setting bias measurement configuration:
normal - Normal measurement configuration (default):
In normal measurement configuration the device
follows normal measurement flow. Pins BP and BN
are left floating and high impedance.
positivebias - Positive bias configuration: In positive bias
configuration, a positive current is forced across
the resistive load on pins BP and BN.
negativebias - Negative bias configuration. In negative bias
configuration, a negative current is forced across
the resistive load on pins BP and BN.
disabled - Only available on HMC5983. Magnetic sensor is disabled.
Temperature sensor is enabled.

New Device Support
* Apex stx104 DAC
- new driver for this PC104 board. Right now DAC support only.
* ADI ad5064
- Add support for ad5625, ad5627, ad5645, ad5665, ad5667 DACs.
- Add support for Linear Technology ltc2606, ltc2607, ltc2609, ltc2616,
ltc2617, ltc2619, ltc2626, ltc2627 and ltc2629.
* ADI ad7192
- add support for the ad7193
* Invensense mpu6050
- substantial rework of driver to use regmap allowing SPI support extending
the now split driver to cover the MPU6000.
* TI adc0832
- new driver supporting ADC0831, ADC0832, ADC0834 and ADC0838 ADCs.
* TI ads1015
- new driver, note that there is an existing hwmon driver. The long term
intention is to probably remove the hwmon driver but for now we just have
guards in place to ensure this driver is not built if that one is enabled.
* TI afe4403
- new driver for this heart rate monitor / pulse oximeter front end chip.
* TI afe4404
- new driver for this heart rate monitor / pulse oximeter front end chip.
Staging Graduations
* mxs-lradc
- A combined general purpose and touch screen (input) device driver.
Originally held in staging to allow reworking into and MFD but as
that wasn't happening and isn't an absolute requirement we are moving
it out of staging.
Driver new features
* ms5611
- triggered buffer support
- IIO_CHAN_INFO_SCALE to aid the triggered buffer support.
Driver cleanups / reworks / fixes
* ad5064
- Use an enum for the register map layout to allow support of additional
chips (precursor to the new support listed above).
- Structural driver changes to allow support of the slightly different
handling for the ltc parts above.
* ad5933
- drop an exceptional & unnecessary for a function pointer.
* ad7606
- Cleanup the repeated copies of pm ops.
- consolidate the various channels specs via a sport of rearranging so only
one version is needed.
* atlas ph sensor
- add select IRQ_WORK
* hmc8543 (soon to move out of staging)
- Comment style fixes
- functionality of suspend and resume was swapped.
* spear-adc
- use devm_clk_dev instead of managing the clk lifetime by hand.
Core
* Use new dmaengine_terminate_sync call to avoid a theoretical race.
* Fix docs for mlock in struct iio_dev as it is correctly taken in some
drivers (docs used to say for core only).
* Add a helper function for calculating the scan index storage size within
the core cutting out some cut and paste versions of the same code.

- Add support for ad5625, ad5627, ad5645, ad5665, ad5667 DACs.
- Add support for Linear Technology ltc2606, ltc2607, ltc2609, ltc2616,
ltc2617, ltc2619, ltc2626, ltc2627 and ltc2629.
* ADI ad7192
- add support for the ad7193
* Invensense mpu6050
- substantial rework of driver to use regmap allowing SPI support extending
the now split driver to cover the MPU6000.
* TI adc0832
- new driver supporting ADC0831, ADC0832, ADC0834 and ADC0838 ADCs.
* TI ads1015
- new driver, note that there is an existing hwmon driver. The long term
intention is to probably remove the hwmon driver but for now we just have
guards in place to ensure this driver is not built if that one is enabled.
* TI afe4403
- new driver for this heart rate monitor / pulse oximeter front end chip.
* TI afe4404
- new driver for this heart rate monitor / pulse oximeter front end chip.
Staging Graduations
* mxs-lradc
- A combined general purpose and touch screen (input) device driver.
Originally held in staging to allow reworking into and MFD but as
that wasn't happening and isn't an absolute requirement we are moving
it out of staging.
Driver new features
* ms5611
- triggered buffer support
- IIO_CHAN_INFO_SCALE to aid the triggered buffer support.
Driver cleanups / reworks / fixes
* ad5064
- Use an enum for the register map layout to allow support of additional
chips (precursor to the new support listed above).
- Structural driver changes to allow support of the slightly different
handling for the ltc parts above.
* ad5933
- drop an exceptional & unnecessary for a function pointer.
* ad7606
- Cleanup the repeated copies of pm ops.
- consolidate the various channels specs via a sport of rearranging so only
one version is needed.
* atlas ph sensor
- add select IRQ_WORK
* hmc8543 (soon to move out of staging)
- Comment style fixes
- functionality of suspend and resume was swapped.
* spear-adc
- use devm_clk_dev instead of managing the clk lifetime by hand.
Core
* Use new dmaengine_terminate_sync call to avoid a theoretical race.
* Fix docs for mlock in struct iio_dev as it is correctly taken in some
drivers (docs used to say for core only).
* Add a helper function for calculating the scan index storage size within
the core cutting out some cut and paste versions of the same code.

The ade7753_spi_read_reg_16() will either successfully read a value
from SPI, or return a failure code without delivering data. However,
the ade7753_stop_device() and ade7753_reset() functions use the returned
data without checking for an error condition first. Gcc detects this
as a possible bug and warns about it:

Third set of new stuff for IIO in the 4.5 cycle.

The big one here is the configfs support which has been a long time in the
works but should allow for cleaner ways to do instantiation of those elements
of IIO that aren't directly connected to specific hardware. Lots of cool new
stuff we can use this for in the works!
New core stuff (basically all configfs support related)
* Configfs support
- Core support (was waiting for a configfs patch that went in around 4.4rc2)
- A little fixlet to add a configfs.h to contain a reference to the
configfs_subsystem structure.
* Some infrastructure to simplify handling of software based triggers
(i.e. ones with no actual hardware associated with them)
* A high resolution timer based trigger. This has been around for years
but until the configfs support was ready we didn't have a sensible way
of instantiating instances of it (the method used for the sysfs_trigger
has never been really satisfactory)
New Device Support
* AMS iAQ Volatile Organic Compounds sensor support.
* Freescale imx7d ADC driver
* Maxim MAX30100 oximeter driver (note that for these devices most of the
smart stuff will be in userspace - effectively they are just light sensors
with some interesting led synchronization as far as the kernel is concerned).
* Microchip mcp3421 support added to the mcp3422 driver.
* TI adc124s021 support added to the adc128s052 driver.
* TI ina219, inda226 power monitors. Note that there is an existing hwmon driver
for these parts, the usecase is somewhat different so it is unclear at this
point if the hwmon driver will eventually be replaced by a bridge from
this driver. In the meantime the Kconfig dependencies should prevent both
from being built.
New driver functionality
* us8152d power management support.
Cleanups, fixups
* Use list_for_each_entry_safe instead of list_for_each_safe with the entry
bit coded longhand.
* Select IRQ_WORK for IIO_DUMMY_EVGEN. This is a fix that somehow got lost

Second set of IIO new drivers, functionality and cleanups for the 4.5 cycle.
The big one here is the configfs support which has been a long time in the
works but should allow for cleaner ways to do instantiation of those elements
of IIO that aren't directly connected to specific hardware. Lots of cool new
stuff we can use this for in the works!
New core stuff (basically all configfs support related)
* Configfs support
- Core support (was waiting for a configfs patch that went in around 4.4rc2)
- A little fixlet to add a configfs.h to contain a reference to the
configfs_subsystem structure.
* Some infrastructure to simplify handling of software based triggers
(i.e. ones with no actual hardware associated with them)
* A high resolution timer based trigger. This has been around for years
but until the configfs support was ready we didn't have a sensible way
of instantiating instances of it (the method used for the sysfs_trigger
has never been really satisfactory)
New Device Support
* AMS iAQ Volatile Organic Compounds sensor support.
* Freescale imx7d ADC driver
* Maxim MAX30100 oximeter driver (note that for these devices most of the
smart stuff will be in userspace - effectively they are just light sensors
with some interesting led synchronization as far as the kernel is concerned).
* Microchip mcp3421 support added to the mcp3422 driver.
* TI adc124s021 support added to the adc128s052 driver.
* TI ina219, inda226 power monitors. Note that there is an existing hwmon driver
for these parts, the usecase is somewhat different so it is unclear at this
point if the hwmon driver will eventually be replaced by a bridge from
this driver. In the meantime the Kconfig dependencies should prevent both
from being built.
New driver functionality
* us8152d power management support.
Cleanups, fixups
* Use list_for_each_entry_safe instead of list_for_each_safe with the entry
bit coded longhand.
* Select IRQ_WORK for IIO_DUMMY_EVGEN. This is a fix that somehow got lost
when the driver was moved so lets do it again.
* st-accel - drop an unused define.
* vz89x, lidar - optimize i2c transactions by using a single i2c tranfers
instead of multiple calls where supported (fall back to smbus calls as
before if not).
* Use dev_get_platdata() in staging drivers: tsl2x7x, adcs and frequency
drivers instead of direct access to the structure element.
The variable u8 **rx_p, is a pointer-to-pointer and hence the check
should
be "if (!*rx_p)" and not "if (!rx_p)".
In the earlier version, checkpatch.pl gave the following check, which
was incorrect:
CHECK: Comparison to NULL could be written "!rx_p"
+ if (*rx_p == NULL) {

The change to using BIT(20) for one of the bit shifts resulted
in a constant becoming unsigned. When combined with the existing
signed constants in a couple of places, this caused possible trouble,
hence the warnings:

The simplest fix is to force LRADC_DELAY_TRIGGER_LRADCS_MASK to be
a shift of an unsigned 0xff rather than a signed one.
This is ugly considering it is the only constant in the driver which
is so forced, but it does deal with the issue.

Usual mixed bag, but the big item perhaps in this series is the DMA buffer
support added by Lars-Peter Clausen. It's been in the works for a long time
and it will be interesting to see what hardware support shows up now that
this is available.
New core features + associate cleanup.
* Add generic DMA buffer infrastructure
* Add a DMAengine framework based buffer
Also associated minor changes.
- Set the device buffer watermark based on the minimum watermark for all
attached buffers rather than just the 'primary' one.
- iio_buffer_init - only set the watermark default if one hasn't already
been provided. This allows simple support for devices with a fixed
watermark.
- read only attribute for watermark on fixed watermark devices.
- add explicit buffer enable/disable callbacks to allow the buffer to
do more than trivial actions when it is being turned on and off.
* IIO_VAL_INT support in write_raw_get_fmt function.
New device support
* Freescale MMA7455/7456L accelerometers
* Memsic MXC6255XC accelerometer
* ST lis2dh12 accelerometer
* TI ADS8688 ADC
* TI Palamas (twl6035/7) gpadc
New driver features
* mma8452
- support either of the available interrupt pins to cope with the case
where board layout has lead to a particular one being connected.
Staging graduation
* Dummy driver
- this driver acts as both an example and a test device for those with
out hardware to develop userspace code against.
Cleanups and minor bits and bobs.
* treewide
- Sort out the ordering of iio_device_register/unregister vs runtime
pm function calls so that it's all nice and consistent and not race
prone.
- Check sscanf return values. None of the cases will actually happen as
the strings are supplied internally, but best to be consistent on this.
* ad7780
- switch over to the gpio descriptor interface and remove the now unused
platform data which gets rid of a header entirely.
* ad7793
- drop a pointless else statement.
* at91_adc
- Swap kmalloc_array in for a kmalloc doing the same job.
* dummy
- get rid of some commented out lines that snuck in during the move of
the driver.
* lm3533-als
- Print an error message on provision of an invalid resistance.
* mcp320x
- Add compatible strings with vendor prefix and deprecate those with
no vendor prefix.
* mxs-lradc
- Use BIT macro in various places rather than shifted ones.
* pa12203001
- Power off the chip if the registration fails.

The ad7606_par and ad7606_spi drivers are not built if CONFIG_AD7606=m,
because kbuild does not currently support <objname>-m syntax. Even if we
add kbuild support, ad7606 fails to link, because of duplicate
module_init definitions. Make the two drivers separate modules, as the
Kconfig help text already suggests.
Also, CONFIG_IIO_BUFFER is a dependency of CONFIG_AD7606, so there is no
need to test for it in the Makefile.

Starting with commit fd2bb310ca (Staging: iio: Move evgen interrupt
generation to irq_work) event processing is handled by calling
both the top half and the threaded part properly simulating real
hardware interrupts making use of threaded interrupts.
This way the processing is split in 2 parts:
* the IRQ handler that runs in IRQ context and only saves the event
timestamp
* the threaded handler that runs in process context, reads the events
and pushes the in the userspace.
If the IRQ handler returns IRQ_HANDLED the threaded handler is not
even being called since the interrupt is considered to be processed.
Because the iio dummy driver processes the events in the threaded
handler the IRQ handler must return IRQ_WAKE_THREAD so that the
threaded part would be awakened and called.
