* 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>;
};
