Subject: iio: adis16400: Add ADIS16445 support
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=72d9c9869df3149316af6cd70585eee15f643f40;p=linux-beck.git

iio: adis16400: Add ADIS16445 support

The ADIS16445 is similar to the ADIS16448, but without the magnetometer and
pressure channels as well as different scale factors for the gyroscope and
accelerometer outputs.
