Subject: [PATCH v4 6/8] dt-bindings: iio: adc: max1027: Mark interrupts as optional
Date: Fri, 11 Oct 2019 16:43:45 +0200 [thread overview]
Message-ID: <20191011144347.19146-7-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20191011144347.19146-1-miquel.raynal@bootlin.com>
The chips have a 'start conversion' and a 'end of conversion' pair of
pins. They can be used but this is absolutely not mandatory as regular
polling is supported by the chip depending on its internal clocking
setup.
There is no physical reason to force the use of interrupts so turn
them optional.
Also, once the interrupt turned optional, these devices fit perfectly
the "trivial devices" described in the generic (yaml) bindings file, so
instead of converting this text file to json schema, we can just add
the relevant compatibles in:
Documentation/devicetree/bindings/trivial-devices.yaml.
