| * Marvell MMP Interrupt controller |
| |
| Required properties: |
| - compatible : Should be "mrvl,mmp-intc", "mrvl,mmp2-intc" or |
| "mrvl,mmp2-mux-intc" |
| - reg : Address and length of the register set of the interrupt controller. |
| If the interrupt controller is intc, address and length means the range |
| of the whold interrupt controller. If the interrupt controller is mux-intc, |
| address and length means one register. Since address of mux-intc is in the |
| range of intc. mux-intc is secondary interrupt controller. |
| - reg-names : Name of the register set of the interrupt controller. It's |
| only required in mux-intc interrupt controller. |
| - interrupts : Should be the port interrupt shared by mux interrupts. It's |
| only required in mux-intc interrupt controller. |
| - interrupt-controller : Identifies the node as an interrupt controller. |
| - #interrupt-cells : Specifies the number of cells needed to encode an |
| interrupt source. |
| - mrvl,intc-nr-irqs : Specifies the number of interrupts in the interrupt |
| controller. |
| - mrvl,clr-mfp-irq : Specifies the interrupt that needs to clear MFP edge |
| detection first. |
| |
| Example: |
| intc: interrupt-controller@d4282000 { |
| compatible = "mrvl,mmp2-intc"; |
| interrupt-controller; |
| #interrupt-cells = <1>; |
| reg = <0xd4282000 0x1000>; |
| mrvl,intc-nr-irqs = <64>; |
| }; |
| |
| intcmux4@d4282150 { |
| compatible = "mrvl,mmp2-mux-intc"; |
| interrupts = <4>; |
| interrupt-controller; |
| #interrupt-cells = <1>; |
| reg = <0x150 0x4>, <0x168 0x4>; |
| reg-names = "mux status", "mux mask"; |
| mrvl,intc-nr-irqs = <2>; |
| }; |
