From: Biju Das <[email protected]> The RZ/G3L DSI IP is similar to the RZ/G2L but has different global PHY timings and also the PLLCLK is ungateble clock. Add the compatible string "renesas,r9a08g046-mipi-dsi" to handle these difference for the Renesas RZ/G3L SoC. The power to DSI region is controlled by SYSC block. Document renesas,sysc-pwrrdy property to handle the power control.
