iio: Add macro to populate struct iio_map array (2017-12-02 13:28:21 +0000)

----------------------------------------------------------------
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.
