12 description: |
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.
