Subject: [PATCH v1 0/2] iio: adc: ti-ads1119: Add driver

From: Francesco Dolcini <francesco.dolcini@...adex.com>

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.
