The ak8974_configure() function is used only from the PM code,
but that can be hidden when CONFIG_PM is disabled:drivers/iio/magnetometer/ak8974.c:201:12: error: 'ak8974_configure' defined but not used [-Werror=unused-function]
This replaces the #ifdef with a __maybe_unused annotation, which
will work correctly in all configurations and avoid the warning,
as the compiler can now see where ak8974_configure is called from.Signed-off-by: Arnd Bergmann

A small rework of the PM code in this driver introduced a harmless
warning when CONFIG_PM_SLEEP is not set:drivers/iio/common/hid-sensors/hid-sensor-trigger.c:212:12: error: 'hid_sensor_resume' defined but not used [-Werror=unused-function]
This removes the #ifdef and instead marks all three PM functions
as __maybe_unused, which covers all possible cases and is harder

These sensors all have Vdd and Vdd_IO lines. This means the
supplies are *not* optional (optional means that the supply is
optional in the electrical sense, not the software sense)
so we need to get the and enable them at all times.If the device tree or board file does not define suitable
regulators for the component, it will be substituted by a
dummy regulator, or, if regulators are disabled altogether,
by stubs. There is no need to use the IS_ERR_OR_NULL() check
that is considered harmful.Cc: Giuseppe Barba

used when possible over the generic channel type scaling.Examples are of IIO_TEMP channel having a generic scaling value, and
another having IIO_MOD_TEMP_AMBIENT modifier with another scaling value.Previously the first scaling value for a channel type would be applied

The comparison for devnr limits is off-by-one, the current check
allows 0 to AD5755_NUM_CHANNELS and the limit should be in fact
0 to AD5755_NUM_CHANNELS - 1. This can lead to an out of bounds

…iio into work-testing
Jonathan writes:
First round of new features, device support and cleanups for IIO in the 4.9 cycle.
Device support
* ak8974
- New driver and bindings for this 2009 vintage magnetometer (it was very
popular back then!)
* atlas-ph-sensor
- ORP sensor support(I had to look up what one of these was)
* cio-dac
- New driver for Measurement Computing DAC boards
* dmard06
- New driver for Domintech DMARDO6 accelerometer. Also vendor prefix.
* dmard09
- New driver for Domintech DMARD09 accelerometer.
* maxim-thermocouple
- max6675 and max31855 new driver
* mt6577 auxdac
- new driver for this Mediatek chip mt2701, mt6577 and mt8173 have this
hardware.
* ti-adc161s626
- new driver for this TI single channel differential ADC.
* vcnl4000
- support vcnl4010 and vcnl4020 which are compatible for all features
currently supported by this driver.New features
* Core
- Allow retrieving of underlying iio_dev from a callback buffer handle.
This is needed to allow client drivers to perform operations such as
configuring the trigger used.
* hid-sensors
- asynchronous resume support to avoid really long resume times.
* kxcjk-1013
- add the mysterious KIOX000A ACPI id seen in the wild.
* Tools
- lsiio now enumerates processed as well as raw channels.Cleanup
* ad7298
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* ad7793
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* ade7854
- checkpatch fixups (alignment of parameters)
* atlas-ph-sensor
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
- Switch to REGCACHE_NONE as there are no useful register to cache.
* bma180
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* hdc100x
- Add mention of the HDC1000 and HDC1008 to the Kconfig help text.
* isl29018
- Add driver specific prefixes to defines and function names.
- Remove excessive logging.
- Drop newlines which add nothing to readability.
- General tidying up of comments.
- Drop I2C_CLASS_HWMON as irrelevant to driver.
* isl29028
- Add driver specific prefixes to defines, enums and function names.
- Drop comma's from available attribute output as not ABI compliant.
- Drop I2C_CLASS_HWMON as irrelevant to driver.
* kxsd9
- devicetree bindings.
* mag3110
- This one wasn't locking to protect against mode switches during
raw_reads. Use the iio_claim_direct_mode function to fix this buglet.
* maxim-theromcouple
- Fix missing selects for triggered buffer support in Kconfig.
* nau7802
- Use complete instead of complete_all as only one completion at a time.
* sx9500
- Use complete instead of complete_all as only one completion at a time.
* us5182d
- Add a missing error code asignment instead of checking the result of
an already checked statement.
* vcnl4000
- Use BIT macro where appropriate.
- Refactor return codes in read_raw callback.
- Add some missing locking for concurrent accesses to the device.

The function mdc_adjust_dirpages is only called on platforms which
don't have pages 4K in size which is why kbuild only reported this

dp pointer before it was kmapped.Signed-off-by: James Simmons

Add Mediatek auxadc driver based on iio.
It will register a device in iio and support iio.

BT_Active and BT_State are being masked with 0x00ffffff so it the subsequent
comparisons with 0xffffffff are therefore a buggy check. Instead, check them
against 0x00ffffff.Unfortunately I couldn't find a datasheet or hardware to see if 0xffffffff
is an expected invalid bit pattern that should be checked before BT_Active and
BT_State are masked with 0x00ffffff, so for now, this fix seems like the least
risky approach.Signed-off-by: Colin Ian King

The Kconfig currently controlling compilation of this code is:
config FSL_MC_BUS
bool "Freescale Management Complex (MC) bus driver"...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.Since the code was already not using module_init, we don't have to change
the initcall and the init ordering remains unchanged with this commit.We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.We don't replace module.h with init.h since the file does make some
references to "struct *module" for processing other modules.Cc: "J. German Rivera"
