Subject: [PATCH] iio:dac:ad5686: Add AD5311R support
Date: Mon, 4 Jun 2018 17:22:07 +0300	[thread overview]
Message-ID: <1528122127-1911-1-git-send-email-stefan.popa@analog.com> (raw)

AD5311R is a single channel DAC with 10-bit precision and i2c interface.
The device includes a 2.5V internal reference which is enabled by default.

This device is similar to AD5691R/AD5692R/AD5693/AD5693R, the only
difference is that it has 10-bit precision.
