8-bit lcd parallel bus interface

We have a 8-bit parallel bus LCD connected to EIM_A21 (DATA16) to EIM_D27(DATA23). The data to to be sent should be RGB565 but in a 8-bit in two clock clock cycles fashion. I know we should change the microcodes found in ipu_disp.c but I have no clue as of how to do this. We are using Linux 3.14.52.


I tried adding RGB565 to the same if statements for YUYV and added some changes to the _ipu_init_dc_mappings function. but it still does not give me two clock cycles per pixel.


Can someone please help.
