Subject: [PATCH 02/10] dt-bindings:iio:dac:dpot-dac: yaml conversion.
Date: Sat, 31 Oct 2020 18:12:34 +0000 [thread overview]
Message-ID: <20201031181242.742301-3-jic23@kernel.org> (raw)
In-Reply-To: <20201031181242.742301-1-jic23@kernel.org>
From: Jonathan Cameron <Jonathan.Cameron@huawei.com>
Txt to yaml format conversion. I dropped the example section
describing the measurement ADC, as that isn't strictly part
of this binding.
Uses the new dt-schema/schema/iio/iio-consumer.yaml schema.
