Subject: [PATCH 0/2] Add settle time support to mux-gpio
Date: Mon, 4 Oct 2021 17:36:38 +0200	[thread overview]
Message-ID: <20211004153640.20650-1-vincent.whitchurch@axis.com> (raw)

On one of our boards we use gpio-mux with iio-mux to read voltages using an
ADC from a few different channels, and on this board the input voltage needs
some time to stabilize after a switch of the mux.

This series add devicetree and driver support for this kind of hardware which
requries a settle time after muxing.

  mux: gpio: Support settle-time-us property
