Subject: [PATCH 2/2] dt-bindings:iio:dac:dpot-dac: yaml conversion.
Date: Sun, 11 Oct 2020 17:30:31 +0100 [thread overview]
Message-ID: <20201011163031.240708-3-jic23@kernel.org> (raw)
In-Reply-To: <20201011163031.240708-1-jic23@kernel.org>
From: Jonathan Cameron <Jonathan.Cameron@huawei.com>
Txt to yaml format conversion. I dropped the example section
describind the measurement ADC, as that isn't strictly part
of this binding. Uses a reference to the new iio-consumers.yaml
binding.
