| * 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>; | |
| }; |
