| Some socs have a large number of interrupts requests to service |
| the needs of its many peripherals and subsystems. All of the |
| interrupt lines from the subsystems are not needed at the same |
| time, so they have to be muxed to the irq-controller appropriately. |
| In such places a interrupt controllers are preceded by an CROSSBAR |
| that provides flexibility in muxing the device requests to the controller |
| inputs. |
| |
| Required properties: |
| - compatible : Should be "ti,irq-crossbar" |
| - reg: Base address and the size of the crossbar registers. |
| - ti,max-irqs: Total number of irqs available at the interrupt controller. |
| - ti,reg-size: Size of a individual register in bytes. Every individual |
| register is assumed to be of same size. Valid sizes are 1, 2, 4. |
| - ti,irqs-reserved: List of the reserved irq lines that are not muxed using |
| crossbar. These interrupt lines are reserved in the soc, |
| so crossbar bar driver should not consider them as free |
| lines. |
| |
| Examples: |
| crossbar_mpu: @4a020000 { |
| compatible = "ti,irq-crossbar"; |
| reg = <0x4a002a48 0x130>; |
| ti,max-irqs = <160>; |
| ti,reg-size = <2>; |
| ti,irqs-reserved = <0 1 2 3 5 6 131 132 139 140>; |
| }; |
