Subject: staging:iio:dac:ad5064: Add AD5025/AD5045/AD5065 support
X-Git-Tag: firefly_0821_release~3680^2~3347^2~105
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=f8be4af1f272d992decdd7389dc37c49b935d216;p=firefly-linux-kernel-4.4.55.git

staging:iio:dac:ad5064: Add AD5025/AD5045/AD5065 support

The AD5025/AD5045/AD5065 are identical to the AD5024/AD5044/AD5064 except that
they have 2 instead of 4 DAC channels.
