   13   The PS8640 is a low power MIPI-to-eDP video format converter supporting
   14   mobile devices with embedded panel resolutions up to 2048 x 1536. The
   15   device accepts a single channel of MIPI DSI v1.1, with up to four lanes
   16   plus clock, at a transmission rate up to 1.5Gbit/sec per lane. The
   17   device outputs eDP v1.4, one or two lanes, at a link rate of up to
   18   3.24Gbit/sec per lane.
