[PATCH 21/24] dt-bindings:iio:cdc:adi,ad7150 binding doc

[Jonathan Cameron <jic23@kernel.org>]

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

Binding covering the ad7150, ad7151 and ad7156 capacitance to digital
convertors.  The only difference between these is how many channels they
have (1 or 2)
