请教在海思hi3531a.dtsi中配置gpio

    1、上电启动hi3531a报错如下：
        gpio-mockup: probe of gpio-mockup failed with error -22
        pl061_gpio 12270000.gpio_chip: PL061 GPIO chip @0x121f0000 registered
    2、在hi3531a.dtsi中配置gpio如下：
        gpio_chip18:gpio_chip@12270000 {
            compatible = "arm,pl061", "arm,primecell";
            reg = <0x12270000 0x10000>;
            interrupts = <GIC_SPI 0x89 IRQ_TYPE_LEVEL_HIGH>;
            clocks = <&clock HI3531A_PERIAXI_CLK>;
            clock-names = "apb_pclk";
            status = "disabled";
        };
