Subject: [PATCH v2 16/29] dt-bindings:iio:dac:ti,dac082s085 yaml conversion
Date: Sat, 31 Oct 2020 13:40:57 +0000 [thread overview]
Message-ID: <20201031134110.724233-17-jic23@kernel.org> (raw)
In-Reply-To: <20201031134110.724233-1-jic23@kernel.org>
From: Jonathan Cameron <Jonathan.Cameron@huawei.com>
Fairly simple conversion with the exception of the XOR between
spi-cpha and spi-cpol.
Is there a better way to specify that?
Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

v2:
* Family typo
* Put back the reference regulator in example.
* Added checking of XOR of spi-cpha and spi-cpol
(dropped Rob Herrings Reviewed-by due to this change)
