Lars-Peter Clausen 87a048ef95 staging:iio:adis16240: Set self_test_no_autoclear flag
The ADIS16201 does not automatically clear the self test flag bit the self
test has been, so clear it manually. Otherwise we'll see a offset caused by
the self-test bias on the output values during normal operation.

Greg Kroah-Hartman eb7bfed901 First round of IIO new device support, features and cleanups for the 4.7 cycle.
New core support
 * UV light modifier (for intensity)
 * UV light index channel type.
 
 New device support
 * hp206c barometer and altimeter
   - new driver.
 * mcp4131 potentiometer
   - new driver supporting lots of parts from Microchip.
 * mma8452
   - FXLS8471Q support
 - NXP LPC18XX SOC ADC
   - new driver.
 - NXP LPC18XX SOC DAC
   - new driver.
 - rockchip_saradc
   - support rk3399
 * st accel
   - h3lis331dl support
 
 Staging driver removals
 * adis16204
   - obsolete part making it hard to get parts to test the driver in order
     to clean it up.
 * adis16220
   - obsolete part making it hard to get the parts test the driver in order
     to clean it up.
 
 Features
 * core
   - convenience functions to claim / release direct access to the device.
     Makes more consistent handling of this corner easier. Used in ad7192 driver.
 * ak8975
   - power regulator support.
 * at91-sama5d2
   - differential channel support.
 * mma8452
   - runtime pm support
   - drop device specific autosleep and use the runtime pm one instead.
 * ms5611
   - DT bindings
   - oversampling ratio support
 
 Cleanups and minor fixes
 * MAINTAINERS
   - Peter got married - hence name change!
 
 * Documentation
   - Fix a typo in in_proximity_raw description.
   - Add some missing docs for iio_buffer_access_funcs.
 
 * Tools
   - update iio_event_monitor names to match new stuff.
   - make generic_buffer look for triggers ending in -trigger as we let these in
   for a number of drivers a long time back and now it is a fairly common
   option.
 
 Drivers
 * staging wide
   - convert bare unsigned usage to unsigned int to comply with coding style.
 * non staging wide:
   - since boiler plate gpio handling of interrupts has been moved into the
    ACPI core we don't need to include gpio/consumer.h in a load of drivers so
    drop it.
 * ad7606
   - fix an endian casting sparse warning.
 * ak8975
   - fix a possible unitialized warning from gcc.
   - drop and unused field left over from earlier cleanups
   - fix a missing regulator_disable on exit.
 * at91-sama5d2
   - typo and indentation
   - missing IOMEM dependency.
   - cleanup mode register usage by avoidling erasing whole thing when changing
   the sampling frequency.
 * bmc150
   - use the core demux and available_scan_masks to simplify buffer handling
   - optimize the transfers in the trigger handler now we have a magic function
   to emulate bulk reads (under circumstances met here).  This matters with some
   rather dumb i2c adapters in particular.
   - use a single regmap_conf for all bus types as they were all the same.
 * bmg160
   - use the core demux and available_scan_masks to simplify the buffer handling
   - optimize the transfers in the trigger handler now we have a magic funciton
   to emulate bulk rads (under circumstances met here).
   - drop gpio interrupt probing from the driver (ACPI) as now handled by the
   ACPI core.
 * ina2xx-adc
   - update the CALIB register when RShunt changes.
   - fix scale for VShunt - in reality this error canceled out when used.
 * isl29028
   - use regmap to retrieve the struct device instead of carrying a second
   copy of it around.
 * kxcjk-1013
   - use core demux
   - optimize i2c transfers in the trigger handler.
 * mcp4531
   - refactor to use a pointer to access model parameters instead of indexing
     into the array each time.
 * mma8452
   - style fixes
   - avoid swtiching to active whenever the config changes
   - add missin i2c_device_id for mma8451
 * mpu6050
   - fix possible NULL dereference.
   - fix the name / chip_id used when ACPI used (otherwise reports as NULL).
 * ms5611
   - fix a missing regulator_disable that left the regulator on during removal.
 * mxc4005
   - drop gpio interrupt handling for ACPI case from driver as the core now
   handles this case.
 * st-sensors
   - note that there are only ever a maximum of 3 axis on current st-sensors
   so just allocate a fixed sized buffer big enough for that.
 * tpl0102
   - change the i2c_check_functionality condition to bring it inline with other
     IIO users as EOPNOTSUPP.
 * tsl2563
   - replace deprecated flush_scheduled_work

Alison Schofield 5e3d1d520f staging: iio: meter: remove fixme comment on device remove
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.

Amitoj Kaur Chawla 09b9da3399 staging: iio: adc: Replace of_iomap() with devm_ioremap_resource()
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.

Greg Kroah-Hartman ec3c13e4ac Third set of IIO new device support, features and cleanups for the 4.6 cycle.
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.

Lars-Peter Clausen c720842e36 staging:iio: Remove periodic RTC trigger driver
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.
