Subject: [PATCH v2 1/3] dt-bindings:iio:adc: add generic settling-time-us and average-samples channel properties
Date: Fri, 12 Mar 2021 11:55:13 +0100	[thread overview]
Message-ID: <20210312105515.32055-2-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20210312105515.32055-1-o.rempel@pengutronix.de>

Settling time and over sampling is a typical challenge for different IIO ADC
devices. So, introduce channel specific settling-time-us and average-samples
properties to cover this use case.
