Support for Power Button #17

Closed qzed closed 2 years ago

qzed commented 2 years ago

It seems that the PMC8180A handles the power-button in some non-trivial way. This already seems to be implemented in pmc8180.dtsi as:

&spmi_bus {
    pmc8180_0: pmic@0 {
        compatible = "qcom,pm8150", "qcom,spmi-pmic";
        reg = <0x0 SPMI_USID>;
        #address-cells = <1>;
        #size-cells = <0>;

        pon: power-on@800 {
            compatible = "qcom,pm8916-pon";
            reg = <0x0800>;
            pwrkey {
                compatible = "qcom,pm8941-pwrkey";
                interrupts = <0x0 0x8 0x0 IRQ_TYPE_EDGE_BOTH>;
                debounce = <15625>;
                bias-pull-up;
                linux,code = <KEY_POWER>;

                status = "disabled";
            };
        };
    };
};

It is currently disabled by default. We should test whether this works.
