+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>;
+ };
