[RFC v1 0/4] iio: new chemical sensor framework and channel types

Show all headers | View raw

Initial RFC for new chemical sensor framework, IIO_CONCENTRATION,
and IIO_RESISTANCE channel types.

Important notes:
* Not been tested on real hardware yet but that isn't the main RFC reason and
  once hardware is in hand it will be verified
* Reason the IIO_CONCENTRATION type isn't in percent but has modifiers for ppm
  and ppb is the scale value for the latter would cause a integer overflow
  using IIO_VAL_FRACTIONAL

Matt Ranostay (4):
  iio: chemical: Add IIO_CONCENTRATION channel type
  iio: resistance: add IIO_RESISTANCE channel type
  devicetree: add SGX Sensortech vendor id
  iio: chemical: add SGX VZ89x VOC sensor support
