From: Biju Das <biju.das.jz@bp.renesas.com> The DU block on the RZ/G3L SoC is identical to the one found on the RZ/G2L SoC. However, it supports the DSI, DPI, and LVDS interfaces, while the RZ/G2L supports only the DSI and DPI interfaces. Due to this difference, a SoC-specific compatible string, 'renesas,r9a08g046-du', is added for the RZ/G3L SoC.
