08a3380551 iio: core: implement iio_device_{claim|release}_direct_mode()
It is often the case that the driver wants to be sure a device stays
in direct mode while it is executing a task or series of tasks.  To
accomplish this today, the driver performs this sequence: 1) take the
device state lock, 2) verify it is not in a buffered mode, 3) execute
some tasks, and 4) release that lock.

This patch introduces a pair of helper functions that simplify these
steps and make it more semantically expressive.

iio_device_claim_direct_mode()
        If the device is not in any buffered mode it is guaranteed
        to stay that way until iio_release_direct_mode() is called.

iio_device_release_direct_mode()
        Release the claim. Device is no longer guaranteed to stay
        in direct mode.

e8731180fb iio: mma8452: add support for FXLS8471Q
This adds support for Freescale's (now NXP's) FXLS8471Q accelerometer.

We use MMA8451Q's configuration because for what the driver supports,
FXLS8471Q is the same.

Support for FXLS8471Q's features (fast SPI interface and a larger FIFO,
among others) can be added to this driver anytime.

See it's datasheet for the details:

96c0cb2bbf iio: mma8452: add support for runtime power management
This adds support for runtime power management and, if configured, activates

Inactivity means no read of acceleration values and no events triggered or

e866853d67 iio: mma8452: avoid switching to active because of config change
The devices' config registers can only be changed in standby mode.
Up until now the driver just held the device *always* active, so for
changing a config it was *always* necessary to switch to standby.

For upcoming support for runtime pm, the device can as well be in standby
mode. Instead of putting runtime pm functions in there, just keep the
device in standby if it already is. This section is protected by a lock
after all.

the I2C and SPI access. However, it fails to ensure that regmap_spi
is actually present:

drivers/iio/built-in.o: In function `afe4403_probe':
:(.text+0x9bf8): undefined reference to `__devm_regmap_init_spi'

This adds a Kconfig select statement like the afe4404 I2C driver
has.

Greg Kroah-Hartman
d9750a2f9e 2nd round of new IIO device support, features and cleanups for the 4.6 cycle.
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.

ecc24e72f4 iio: adc: Add TI ADS1015 ADC driver support
The driver has sysfs readings with runtime PM support for power saving.
It also offers buffer support that can be used together with IIO software
triggers.
