From cc21231ef0995a6507f2976e40fa473b82e84a44 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron <Jonathan.Cameron@huawei.com> Date: Sun, 26 Jun 2022 13:29:36 +0100 Subject: [PATCH] iio: cdc: ad7746: Add device specific ABI documentation. The datasheet description of offset calibration is complex, so for that on just refer the reader to the device datasheet.
