| Cirrus Logic CLPS711X Interrupt Controller |
| |
| Required properties: |
| |
| - compatible: Should be "cirrus,clps711x-intc". |
| - reg: Specifies base physical address of the registers set. |
| - interrupt-controller: Identifies the node as an interrupt controller. |
| - #interrupt-cells: Specifies the number of cells needed to encode an |
| interrupt source. The value shall be 1. |
| |
| The interrupt sources are as follows: |
| ID Name Description |

| 1: BLINT Battery low (FIQ) |
| 3: MCINT Media changed (FIQ) |
| 4: CSINT CODEC sound |
| 5: EINT1 External 1 |
| 6: EINT2 External 2 |
| 7: EINT3 External 3 |
| 8: TC1OI TC1 under flow |
| 9: TC2OI TC2 under flow |
| 10: RTCMI RTC compare match |
| 11: TINT 64Hz tick |
| 12: UTXINT1 UART1 transmit FIFO half empty |
| 13: URXINT1 UART1 receive FIFO half full |
| 14: UMSINT UART1 modem status changed |
| 15: SSEOTI SSI1 end of transfer |
| 16: KBDINT Keyboard |
| 17: SS2RX SSI2 receive FIFO half or greater full |
| 18: SS2TX SSI2 transmit FIFO less than half empty |
| 28: UTXINT2 UART2 transmit FIFO half empty |
| 29: URXINT2 UART2 receive FIFO half full |
| 32: DAIINT DAI interface (FIQ) |

| Example: |
| intc: interrupt-controller { |
| compatible = "cirrus,clps711x-intc"; |
| reg = <0x80000000 0x4000>; |
| interrupt-controller; |
| #interrupt-cells = <1>; |
| }; |
