Subject: [PATCH v3 15/17] iio: cdc: ad7746: Add device specific ABI documentation.
Date: Sun, 26 Jun 2022 13:29:36 +0100 [thread overview]
Message-ID: <20220626122938.582107-16-jic23@kernel.org> (raw)
In-Reply-To: <20220626122938.582107-1-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".
