[PATCH v2 0/2] iio: adc: ti-ads1119: Add driver

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@xxxxxxxxxxx>

The ADS1119 is a precision, 16-bit, analog-to-digital converter (ADC)
that features two differential or four single-ended inputs through a
flexible input multiplexer (MUX), rail-to-rail input
buffers, a programmable gain stage, a voltage reference, and an
oscillator.

Apart from normal single conversion, the driver also supports
continuous conversion mode using a triggered buffer. However, in this
mode only one channel can be scanned at a time, and it only uses the data
ready interrupt as a trigger. This is because the device channels are
multiplexed, and using its own data ready interrupt as a trigger guarantees
the signal sampling frequency.

v2:
 bindings:
 - add diff-channels and single-channel
 - remove ti,gain and ti,datarate
 - more details on the patch changelog

 driver:
 - adaptation for the binding changes
 - changed i2c read/write to the device (not using regmap anymore, use FIELD macros)
 - more details on the patch changelog
