Subject: iio:ad5446: Add support for the ad5300/ad5310/ad5320
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2fafbce25063ae2732f2f2d9f853f1d97145eab5;p=linux-beck.git

iio:ad5446: Add support for the ad5300/ad5310/ad5320

The ad5300/ad5310/ad5320 is a family of single channel DACs with a SPI interface
similar to the ad5601/ad5611/ad5621 but use a different shift factor for the
data word.

While we are at it also reorder the device part numbers in the ad5446 driver
Kconfig to be ordered alphabetically.
