Hi Sato-san, Documentation/devicetree/bindings/memory-controllers/renesas,h8300-bsc.txt says: +Required properties: + - compatible: Must be "renesas,h8300-bsc". + - reg: Base address and length of BSC registers. But the example uses another compatible value, which is not documented, in addition to the one above: +Example. + bsc: memory-controller@fee01e { + compatible = "renesas,h8300h-bsc", "renesas,h8300-bsc"; + reg = <0xfee01e 8>; + }; The example matches the simulator's dts: h8300h_sim.dts: compatible = "renesas,h8300h-bsc", "renesas,h8300-bsc"; But the dtses for real hardware use yet another undocumented value: edosk2674.dts: compatible = "renesas,h8s-bsc", "renesas,h8300-bsc"; h8s_sim.dts: compatible = "renesas,h8s-bsc", "renesas,h8300-bsc"; Can you please fix this? BTW, scripts/checkpatch.pl should have told you about some of the discrepancies. Thanks!
