Cirrus Logic CLPS711X Interrupt Controller
Required properties:
- compatible: Should be "cirrus,ep7209-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,ep7312-intc", "cirrus,ep7209-intc";
reg = <0x80000000 0x4000>;
interrupt-controller;
#interrupt-cells = <1>;
};
