Both RZ/G2L and RZ/G2LC have an LCDC. I believe the lack of parallel data support on RZ/G2LC is just a limitation of the package?

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. Regards, Biju
Hi Biju, Thank you for the patch. On Wed, Mar 16, 2022 at 01:10:54PM +0000, Biju Das wrote: > Extend the Renesas DU display bindings to support the r9a07g044l > DU module found on RZ/G2L LCDC. Stupid question, but as this DU and the R-Car DU are completely different pieces of hardware, wouldn't a separate bindings file make sense ?
