[0/5] Expand Semtech SAR Sensors support

Message

Gwendal Grignou Oct. 30, 2021, 11:18 a.m. UTC

Add a new Semtech SAR sensor SX9324.
Instead of recopying 1/3 of the sx9310 driver, move common code in a new
file. It will be used again for the next sensor, SX9360.

While moving the functions to the common file, noticed that constants are
sometimes used instead of chan->scan_type.realbits.

Gwendal Grignou (5):
  iio: Use .realbits to extend a small signed integer
  iio: sx9310: Extract common Semtech sensor logic
  iio: proximity: Add SX9324 support
  dt-bindings: iio: Add sx9324 binding
  iio: sx9324: Add dt_bidding support
