Subject: [PATCH v5 0/2] iio: adc: add Nuvoton NCT7201 ADC driver

Change since version 5:
 - Fix comments
 - Add NUVOTON NCT7201 IIO DRIVER section in MAINTAINERS
 - Add vdd-supply and vref-supply to the DT example
 - Remove mutex since the regmap should already have an internal lock
 - Remove redundant assigning values
 - Check errors on regmap_write

Change since version 4:
 - Fix comments
 - Add interrupts and reset-gpios to the DT example
 - Use the FIELD_PREP and FIELD_GET
 - Add use_single_write in regmap_config
 - Use regmap_access_table

Change since version 3:
 - Fix comments
 - Don't put nct720"x" in the name, just call it nct7201
 - Remove differential inputs until conversions are finished
 - Add NCT7201_ prefix in all macros and avoid the tables
 - Correct event threshold values in raw units
 - Add with and without interrupt callback function to have the event
   config part and one that doesn't
 - Remove print an error message if regmap_wirte failed case

Change since version 2:
 - Remvoe read-vin-data-size property, default use read word vin data
 - Use regmap instead of i2c smbus API
 - IIO should be IIO_CHAN_INFO_RAW and _SCALE not _PROCESSED
 - Use dev_xxx_probe in probe function and dev_xxx in other functions
 - Use devm_iio_device_register replace of iio_device_register
 - Use guard(mutex) replace of mutex_lock
 - Use get_unaligned_le16 conversion API

Changes since version 1:
 - Add new property in iio:adc binding document
 - Add new driver for Nuvoton NCT720x driver
