1Cirrus Logic CLPS711X Interrupt Controller 2 3Required properties: 4 5- compatible: Should be "cirrus,ep7209-intc". 6- reg: Specifies base physical address of the registers set. 7- interrupt-controller: Identifies the node as an interrupt controller. 8- #interrupt-cells: Specifies the number of cells needed to encode an 9 interrupt source. The value shall be 1. 10 11The interrupt sources are as follows: 12ID Name Description 13--------------------------- 141: BLINT Battery low (FIQ) 153: MCINT Media changed (FIQ) 164: CSINT CODEC sound 175: EINT1 External 1 186: EINT2 External 2 197: EINT3 External 3 208: TC1OI TC1 under flow 219: TC2OI TC2 under flow 2210: RTCMI RTC compare match 2311: TINT 64Hz tick 2412: UTXINT1 UART1 transmit FIFO half empty 2513: URXINT1 UART1 receive FIFO half full 2614: UMSINT UART1 modem status changed 2715: SSEOTI SSI1 end of transfer 2816: KBDINT Keyboard 2917: SS2RX SSI2 receive FIFO half or greater full 3018: SS2TX SSI2 transmit FIFO less than half empty 3128: UTXINT2 UART2 transmit FIFO half empty 3229: URXINT2 UART2 receive FIFO half full 3332: DAIINT DAI interface (FIQ) 34 35Example: 36 intc: interrupt-controller { 37 compatible = "cirrus,ep7312-intc", "cirrus,ep7209-intc"; 38 reg = <0x80000000 0x4000>; 39 interrupt-controller; 40 #interrupt-cells = <1>; 41 }; 42
