[PATCH v2 0/2] iio: adc: Add driver support for AD7292

[Marcelo Schmitt]

This patchset adds a basic driver for the AD7292 ADC/DAC system along
with device tree binding documentation.

Changelog V2:
- made SPI rx/tx buffers separated fields in the state struct
- adjusted spi_transfer tx_buf pointer
- at probe, stored vref supply for later reference 
- removed regulator_get_voltage() from read_raw() INFO_SCALE
- added a comment to make clear when internal voltage reference will be used
- use standard channel definition to specify the ADC channels in dt-binding doc
