[PATCH v2 0/2] iio: adc: ti-ads112c14: buffered read support

Posted by David Lechner (TI) 4 hours ago

This is the next phase of ti-ads112c14 support after [1].

Some design decision notes:
* This just includes support for software triggers using the single-shot
  mode for now. We will follow up later with DRDY interrupt support and
  a new trigger to allow using the continuous mode.
* We wanted to enable CRC checking for data integrity, so it is just
  always enabled. This way, the buffer layout is always the same. I
  don't think we have an existing control for toggling CRC checking
  anyway.
