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>; };
