1 Cirrus Logic CLPS711X Interrupt Controller
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.
11 The interrupt sources are as follows:
13 ---------------------------
14 1: BLINT Battery low (FIQ)
15 3: MCINT Media changed (FIQ)
20 8: TC1OI TC1 under flow
21 9: TC2OI TC2 under flow
22 10: RTCMI RTC compare match
24 12: UTXINT1 UART1 transmit FIFO half empty
25 13: URXINT1 UART1 receive FIFO half full
26 14: UMSINT UART1 modem status changed
27 15: SSEOTI SSI1 end of transfer
29 17: SS2RX SSI2 receive FIFO half or greater full
30 18: SS2TX SSI2 transmit FIFO less than half empty
31 28: UTXINT2 UART2 transmit FIFO half empty
32 29: URXINT2 UART2 receive FIFO half full
33 32: DAIINT DAI interface (FIQ)
