title: MIPI DSI to eDP Video Format Converter

maintainers:
  - Nicolas Boichat <drinkcat@chromium.org>

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