Subject: [PATCH 6/7] dt-bindings: iio: adc: max1027: Mark interrupts as optional
Date: Wed,  2 Oct 2019 14:30:24 +0200	[thread overview]
Message-ID: <20191002123025.21413-7-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20191002123025.21413-1-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.
