In linux kernel since version 5.1 (release Date: 2019-05-05)  

This adds support for SPI multiplexers. Each SPI mux will be
accessible as a SPI controller, the devices behind the mux will appear
to be chip selects on this controller. It is still necessary to
select one or more specific mux-controller drivers.
