I found weird behavior of the LVDS.

Only reasonable explanation is that  LDB_CTRL bits 5 and 6 are exchanged.

Another possible typo in the document is description of bit_mapping_ch0:

0 Use SPWG standard.
1 Use JEIDA standard.

I found that VESA (I believe that the same as SPWG) LVDS display works properly if the bit_mapping_ch0 is set.

 

After modification of the bits definition the color on the 18 bpp LCD of Touch Revolution became proper.
