The RZ/G3E Soc has 2 LCD controller (LCDC), contain a Frame Compression Processor (FCPVD), a Video Signal Processor (VSPD), Video Signal Processor (VSPD), and Display Unit (DU).
- LCDC0 supports DSI and LVDS (single or dual-channel) outputs. - LCDC1 supports DSI, LVDS (single-channel), and RGB outputs. Add new SoC-specific compatible string 'renesas,r9a09g047-du'. Signed-off-by: Tommaso Merciai <[email protected]> --- v8->v9: - Step back to v5 + added refusal of port3 for others SoCs. - Adjusted order and ports description.
