Subject: [PATCH v2 15/17] iio: cdc: ad7746: Add device specific ABI documentation.
Date: Sun, 19 Jun 2022 19:58:37 +0100	[thread overview]
Message-ID: <20220619185839.1363503-16-jic23@kernel.org> (raw)
In-Reply-To: <20220619185839.1363503-1-jic23@kernel.org>

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

The datasheet description of offset calibration is complex, so for that
on just refer the reader to the device datasheet.

+Description:
+		Write 1 to trigger a calibration of the calibbias or
+		calibscale. For calibscale, a fullscale capacitance should
+		be connected to the capacitance input and a
+		calibscale_calibration then started.  For calibbias see
+		the device datasheet section on "capacitive system offset
+		calibration".
