The interrupt controller, or the HW block containing it, is referred to occasionally as "armctrl" in the SoC documentation, hence naming of this binding. Required properties: - compatible : should be "brcm,bcm2835-armctrl-ic.txt" - reg : Specifies base physical address and size of the registers. - 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 2. The 1st cell is the interrupt bank; 0 for interrupts in the "IRQ basic pending" register, or 1/2 respectively for interrupts in the "IRQ pending 1/2" register. The 2nd cell contains the interrupt number within the bank. Valid values are 0..7 for bank 0, and 0..31 for bank 1. The interrupt sources are as follows: Bank 0: 0: ARM_TIMER 1: ARM_MAILBOX 2: ARM_DOORBELL_0 3: ARM_DOORBELL_1 4: VPU0_HALTED 5: VPU1_HALTED 6: ILLEGAL_TYPE0 7: ILLEGAL_TYPE1 Bank 1: 0: TIMER0 1: TIMER1 2: TIMER2 3: TIMER3 4: CODEC0 5: CODEC1 6: CODEC2 7: VC_JPEG 8: ISP 9: VC_USB 10: VC_3D 11: TRANSPOSER 12: MULTICORESYNC0 13: MULTICORESYNC1 14: MULTICORESYNC2 15: MULTICORESYNC3 16: DMA0 17: DMA1 18: VC_DMA2 19: VC_DMA3 20: DMA4 21: DMA5 22: DMA6 23: DMA7 24: DMA8 25: DMA9 26: DMA10 27: DMA11 28: DMA12 29: AUX 30: ARM 31: VPUDMA Bank 2: 0: HOSTPORT 1: VIDEOSCALER 2: CCP2TX 3: SDC 4: DSI0 5: AVE 6: CAM0 7: CAM1 8: HDMI0 9: HDMI1 10: PIXELVALVE1 11: I2CSPISLV 12: DSI1 13: PWA0 14: PWA1 15: CPR 16: SMI 17: GPIO0 18: GPIO1 19: GPIO2 20: GPIO3 21: VC_I2C 22: VC_SPI 23: VC_I2SPCM 24: VC_SDIO 25: VC_UART 26: SLIMBUS 27: VEC 28: CPG 29: RNG 30: VC_ARASANSDIO 31: AVSPMON Example: intc: interrupt-controller { compatible = "brcm,bcm2835-armctrl-ic"; reg = <0x7e00b200 0x200>; interrupt-controller; #interrupt-cells = <2>; }; Documentation/devicetree/bindings/timer/brcm,bcm2835-system-timer.txt 0 → 100644 +22 −0 Original line number Diff line number Diff line BCM2835 System Timer The System Timer peripheral provides four 32-bit timer channels and a single 64-bit free running counter.
