The dt-binding update part is not very clear to me.

Currently on the imx6sx-sdb.dts we have:

&qspi2 {
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_qspi2>;
    status = "okay";

    flash0: n25q256a at 0 {
        #address-cells = <1>;
        #size-cells = <1>;
        compatible = "micron,n25q256a", "jedec,spi-nor";
        spi-max-frequency = <29000000>;
        reg = <0>;
    };

    flash1: n25q256a at 1 {
        #address-cells = <1>;
        #size-cells = <1>;
        compatible = "micron,n25q256a", "jedec,spi-nor";
        spi-max-frequency = <29000000>;
        reg = <1>;
    };
};


The reg requirement is already present as part of
Documentation/devicetree/bindings/mtd/jedec,spi-nor.txt.

Are you proposing that I add a comment to
Documentation/devicetree/bindings/mtd/fsl-quadspi.txt saying that the
Flash sub-nodes must contain a reg property?

Please clarify.

Thanks
