imx6qp ipu display

Dear all,

   The configuration for 16bit VYUY is below in mxc_ipu.

/* IPU_PIX_FMT_VYUY 16bit width */
_ipu_dc_map_clear(ipu, 5);
_ipu_dc_map_config(ipu, 5, 0, 7, 0xFF);
_ipu_dc_map_config(ipu, 5, 1, 0, 0x0);
_ipu_dc_map_config(ipu, 5, 2, 15, 0xFF);
_ipu_dc_map_clear(ipu, 6);
_ipu_dc_map_config(ipu, 6, 0, 0, 0x0);
_ipu_dc_map_config(ipu, 6, 1, 7, 0xFF);
_ipu_dc_map_config(ipu, 6, 2, 15, 0xFF);

Now we want to use 20bit VYUY format for LCD display, 

We use disp0_data[19:0] as the data bus. what's right configuration for it?

thanks?

unfortunately, mx6 doesn't support 20bits output. only solution is that you can connect mx6 16bits to the two high 8bits of display, the two low 2bits connect to ground, then you can refer to the patch in the link as below:
