Subject: [PATCH v3 1/3] dt-bindings:iio:adc: add generic settling-time-us and oversampling-ratio channel properties
Date: Fri, 19 Mar 2021 15:45:07 +0100 [thread overview]
Message-ID: <20210319144509.7627-2-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20210319144509.7627-1-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 oversampling-ratio
properties to cover this use case.
