This patch removes macros in XGI_main.h that contain a xgifb_info
variable.  These macros hurt readability by hiding said variable
behind a define.  It also uses a temporary variable to keep the
replaced code from getting too long.

The aead files was using a func naming convention which was inconsistent
(ssi vs. cc), included a useless prefix (ssi_aead) and often used
too long function names producing monster func names such as
ssi_aead_gcm_setup_ghash_desc() that made the call site code hard
to read.

Make the code more readable by switching to a simpler, consistent naming
conventionfor all the function defined in the file.

First set of new device support, cleanups and features for IIO in the 4.16 cycle

New device support
* IDT Z0PT2201 ambient light and UVB sensor
  - new driver and DT bindings.
* MAX30102 (pulse oximetery sensor)
  - support for MAX30105 sensor (smoke detector)  Just goes to show
    how two supposedly totally different applications can use very similar
    devices.
* UVIS25 UV sensor
  - new driver and DT bindings.

Major new features
* at91-sama5d2-adc
  - DMA support including bindings + a fix for an issue with acking the
    interrupt to prevent false overrun reports.
* ina2xx
  - allow control of shunt voltage PGA and bus voltage range to give better
    accuracy in some cases.
* stm32-adc
  - support differential channels (precursor patch reworked how channel names
    were created to enable this).

Cleanups / minor fixes / features
* core
  - mark a deliberate switch fallthrough.
  - macro to populate struct iio_map array elements.
* docs
  - typo fix.
* MAINTAINERS
  - add some missing entries for IIO ABI files.

* ad7152
  - tidy up unlocking paths.
* ad7746
  - tidy up unlocking paths.
* ak8975
  - add an ACPI id found on a prototype board.
* aspeed-adc
  - deassert reset in probe to ensure device is usable.
* bfin-trigger
  - platform_get_irq return value fixing.
* bmc150
  - OF device ID table for i2c (spi to be done).
* cros_ec
  - unused variable cleanup.
* da208
  - ACPI binding seen on Linx 820 tablet.
* ina2xx
  - shift down raw value to drop status flags from value (likely to have
    been hidden in the noise).
  - tidy up a special case that wasn't needed.
* inv_mpu6050
  - i2c_unregister_device knows about null values so don't check it twice.
* kxsd9
  - fix missing MODULE_LICENSE and MODULE_DESCRIPTION.
* max30102
  - missing new lines in dev_err.
  - inconsistent punctuation in error messages.
  - fix LED mode mask number of bits.
  - check return value of power mode functions to handle errors.
  - introduce an intensity channel macro to reduce duplication.
  - fix minor issue where device wasn't necessarily enabled during
    a get temperature.
  - use indicies for LED channels.
  - move the mode seetting to buffer_postenable - precursor to new device
    support.
  - prepare to allow copying of varying numbers of measurement.
* meson-saradc
  - drop irrelevant clock and update bindings.
* mma8452
  - a couple of renames for readability reasons.
* qcom_vadc
  - fix missing MODULE_LICENSE and MODULE_DESCRIPTION.
* st_accel
  - drop an unused variable.
* sx9500
  - add an ACPI id found on a prototype board.

The GPIO core provides a handy GPIO_LOOKUP() macro to populate a struct
gpiod_lookup array without having to spell out attribute names (but
still avoid breakage when attributes within the struct are rearranged
or added).

The axp288_adc.c driver uses a similar macro to populate a struct
iio_map array.  Make it available to others.

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

The I2C device ID table entries have the .driver_data field set, but they
are not used in the driver so weren't set in the OF device table entries.

The ASPEED SoC must deassert a reset in order to use the ADC peripheral.

The device tree bindings are updated to document the resets phandle, and
the example is updated to match what is expected for both the reset and
clock phandle. Note that the bindings should have always had the reset
controller, as the hardware is unusable without it.
