How to configure FB and IPU to output to 8-bit parallel display interface?

[dehuanxin]

I'm trying to connect IMX6Q SoC to a parallel LCD panel.

The hardware only connects lower 8 bits of the parallel display port to the LCD.

How do I configure the IPU and FB to output interleaved RGB data?

Hi Dehuan

thia could be done in early IPU versions (like i.MX35) with register

DI_DISP_ACC_CC, unfortunately this register is removed in i.MX6 IPU.

Best regards

I see this patch implements YUV422 via 8 bit parallel interface.

Patch to Support BT656 and BT1120 Output For i.MX6 BSP

I thin need to take a deeper look to see how that is done.
