- * Intel Advanced Configuration and Power Interface General Purpose Events
- This describes an interrupt controller which provides access to GPEs supported
- by the SoC.
- Required properties:
- - compatible : "intel,acpi-gpe"
- - interrupt-controller : Identifies the node as an interrupt controller
- - #interrupt-cells : The number of cells to define the interrupts. Must be 2:
- cell 0: interrupt number (normally >=32 since GPEs below that are reserved)
- cell 1: 0 (flags, but none are currently defined)
- - reg : The register bank for the controller (set this to the ACPI base).
- Example:
- general-purpose-events {
- reg = <IOMAP_ACPI_BASE IOMAP_ACPI_SIZE>;
- compatible = "intel,acpi-gpe";
- interrupt-controller;
- #interrupt-cells = <2>;
- };
- ...
- tpm@50 {
- reg = <0x50>;
- compatible = "google,cr50";
- ready-gpios = <&gpio_n 0x1c GPIO_ACTIVE_LOW>;
- interrupts-extended = <&acpi_gpe 0x3c 0>;
- };
