+
+description: |
+  The Freescale i.MX8qm/qxp LVDS Display Bridge(LDB) has two channels.
+
+  For i.MX8qxp LDB, each channel supports up to 24bpp parallel input color
+  format and can map the input to VESA or JEIDA standards.  The two channels
+  cannot be used simultaneously, that is to say, the user should pick one of
+  them to use.  Two LDB channels from two LDB instances can work together in
+  LDB split mode to support a dual link LVDS display.  The channel indexes
+  have to be different.  Channel0 outputs odd pixels and channel1 outputs
+  even pixels.
+
+  For i.MX8qm LDB, each channel additionally supports up to 30bpp parallel
+  input color format.  The two channels can be used simultaneously, either
+  in dual mode or split mode.  In dual mode, the two channels output identical
+  data.  In split mode, channel0 outputs odd pixels and channel1 outputs even
+  pixels.
