Linux/DM3730: Is it possible to do 2 cycle TDM (RGB565 over 8 bit bus) in MIPI-DPI mode?

Hi, everyone,

I'm trying to update a legacy design to a different LCD panel.

Currently the CPU board and LCD uses RGB888 via 8 bit MIPI-DBI (sys80 style).

The new LCD accepts RGB565/666/888 MIPI-DPI via 16/18/24 bit bus.

To minimize the bridging logic, I'm trying to use the PCLK/DE/HSYNC/VSYNC from the DM3730, set it to output RGB565 via 8 bit bus (2 cycles per pixel) and add logic to buffer 2 cycles of 8 bit data to a 16 bit pixel, and divide PCLK to 1/2.

Question: RGB565 via 8 bit bus is not part of MIPI-DPI2 standard, but is it possible to configure DM3730 to do that?

I'm using DVSDK 4.03 and Linux kernel 2.6.37.
