| * 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>; |
| }; |
