   13   This binding supports DSI to LVDS bridge TC358775
   14 
   15   MIPI DSI-RX Data 4-lane, CLK 1-lane with data rates up to 800 Mbps/lane.
   16   Video frame size:
   17   Up to 1600x1200 24-bit/pixel resolution for single-link LVDS display panel
   18   limited by 135 MHz LVDS speed
   19   Up to WUXGA (1920x1200 24-bit pixels) resolution for dual-link LVDS display
   20   panel, limited by 270 MHz LVDS speed.
