Subject: [PATCH 08/13] dt-bindings: iio: adc: ti,adc12138 yaml conversion.
Date: Sun,  9 Aug 2020 12:17:48 +0100
Message-ID: <20200809111753.156236-9-jic23@kernel.org> (raw)
In-Reply-To: <20200809111753.156236-1-jic23@kernel.org>

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

Simple binding conversion.  Only addition was #io-channel-cells to
allow for potential consumers of the channels on this device.
