| 2 | |
| 3 | OMAP2/3 are using a TI interrupt controller that can support several |
| 4 | configurable number of interrupts. |
| 5 | |
| 6 | Main node required properties: |
| 7 | |
| 8 | - compatible : should be: |
| 9 | "ti,omap2-intc" |
| 10 | - interrupt-controller : Identifies the node as an interrupt controller |
| 11 | - #interrupt-cells : Specifies the number of cells needed to encode an |
| 12 | interrupt source. The type shall be a <u32> and the value shall be 1. |
| 13 | |
| 14 | The cell contains the interrupt number in the range [0-128]. |
| 15 | - ti,intc-size: Number of interrupts handled by the interrupt controller. |
| 16 | - reg: physical base address and size of the intc registers map. |
| 17 | |
| 18 | Example: |
| 19 | |
| 20 | intc: interrupt-controller@1 { |
| 21 | compatible = "ti,omap2-intc"; |
| 22 | interrupt-controller; |
| 23 | #interrupt-cells = <1>; |
| 24 | ti,intc-size = <96>; |
| 25 | reg = <0x48200000 0x1000>; |
| 26 | }; |
