From the block diagram 24-bit video data from DU is connected to both DSI and parallel interface.
However, SoC packaging wise RZ/G2LC supports only DSI interface.
RZ/G2L supports both DSI and parallel interface
RZ/G2LC supports only DSI interface
OK, we could use "renesas,du-r9a07g044" as well.

Biju
