Subject: [PATCH 0/2] SPI bus multiplexing

This is a revisit of two earlier efforts to add more complex mutliplexing to
SPI busses.

https://patchwork.kernel.org/patch/2706151/
https://patchwork.kernel.org/patch/10897255/

This version makes use of the general purpose mux controller which simplifies
things greatly.
