Detailed Description

Devicetree macros for the ITE IT8XXX2 Wake-Up Controller (WUC).

Macros for describing wake-up controller cells used with the ite,it8xxx2-wuc and ite,it8xxx2-wuc-map compatible controllers. A WUC mapping references a WUC group node and the bit mask of the wake-up input within that group; IT8XXX2_WUC_UNUSED_REG is used where a group has no associated edge-trigger register. The WUC_TYPE_EDGE_* flags select the edge trigger mode of a wake-up input.

wuc_wu20: wu20 {
        wucs = <&wuc2 BIT(0)>;
};
