Subject: [PATCH 0/2] SPI bus multiplexing
Date: Wed, 15 Jan 2020 12:38:54 +1300 [thread overview]
Message-ID: <20200114233857.25933-1-chris.packham@alliedtelesis.co.nz> (raw)
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.
