[PATCH 1/2] dt-bindings: mux: gpio-mux: Add property for settle time

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
