Got it

Like iomuxc-gpr in patch 6, the problem is that for those nodes with
simple-mfd backwards compatibility,
there could be possibly some random subnodes since there're generic
combo registers.
That's why i use additionalProperties true to cover it.
Do you think it's ok?

e.g.
anatop: anatop at 20c8000 {
        compatible = "fsl,imx6q-anatop", "syscon", "simple-mfd";
        reg = <0x020c8000 0x1000>;
        interrupts = <0 49 IRQ_TYPE_LEVEL_HIGH>,
                     <0 54 IRQ_TYPE_LEVEL_HIGH>,
                     <0 127 IRQ_TYPE_LEVEL_HIGH>;

        reg_vdd1p1: regulator-1p1 {
                compatible = "fsl,anatop-regulator";
                regulator-name = "vdd1p1";
                regulator-min-microvolt = <1000000>;
                regulator-max-microvolt = <1200000>;
                ...
        };

        tempmon: tempmon {
                compatible = "fsl,imx6q-tempmon";
                interrupt-parent = <&gpc>;
                interrupts = <0 49 IRQ_TYPE_LEVEL_HIGH>;
                fsl,tempmon = <&anatop>;
                nvmem-cells = <&tempmon_calib>, <&tempmon_temp_grade>;
                nvmem-cell-names = "calib", "temp_grade";
                clocks = <&clks IMX6QDL_CLK_PLL3_USB_OTG>;
                #thermal-sensor-cells = <0>;
        };
};

gpr: iomuxc-gpr at 20e0000 {
        compatible = "fsl,imx6q-iomuxc-gpr", "syscon", "simple-mfd";
        reg = <0x20e0000 0x38>;

        mux: mux-controller {
                compatible = "mmio-mux";
                #mux-control-cells = <1>;
        };
};

Got it
