Subject: [PATCH v2 2/3] dt-bindings: iio: io-channel-mux: Add property for settle time
Date: Thu, 7 Oct 2021 15:46:40 +0200 [thread overview]
Message-ID: <20211007134641.13417-3-vincent.whitchurch@axis.com> (raw)
In-Reply-To: <20211007134641.13417-1-vincent.whitchurch@axis.com>
Hardware may require some time for the muxed analog signals to settle
after the muxing is changed. Allow this time to be specified in the
devicetree.
