12description: |
13  The Mixel MIPI-DSI PHY IP block is e.g. found on i.MX8 platforms (along the
14  MIPI-DSI IP from Northwest Logic). It represents the physical layer for the
15  electrical signals for DSI.
16
17  The Mixel PHY IP block found on i.MX8qxp is a combo PHY that can work
18  in either MIPI-DSI PHY mode or LVDS PHY mode.
