Subject: [PATCH 0/2] iio: Add support for TI ADS1X18 ADCs

Hi,

This series adds a new driver for TI ADS1X18 SPI devices.

This is my first time contributing to the IIO subsystem and making
dt-bindings documentation, so (don't) go easy on me :p.

As explained in Patch 2 changelog, the DRDY interrupt line is shared
with the MOSI pin. This awkward quirk is also found on some Analog
Devices sigma-delta SPI ADCs, so the interrupt and trigger design is
inspired by those.

Thank you in advance for your reviews.
