+Broadcom BCM6345 Level 1 periphery interrupt controller
+
+This block is a interrupt controller that is typically connected directly
+to one of the HW INT lines on each CPU. Every BCM63XX xDSL chip since
+BCM6345 has contained this hardware.
+
+Key elements of the hardware design include:
+
+- 32, 64, or 128 incoming level IRQ lines
+
+- All onchip peripherals are wired directly to an L2 input
+
+- A separate instance of the register set for each CPU, allowing individual
+ peripheral IRQs to be routed to any CPU
+
+- No atomic mask/unmask operations
+
+- No polarity/level/edge settings
+
+- No FIFO or priority encoder logic; software is expected to read all
+ 1-4 status words to determine which IRQs are pending
+
+Required properties:
+
+- compatible: should be "brcm,bcm6345-l2-intc"
+- reg: specifies the base physical address and size of the registers;
+ multiple regs may be specified, and must match the amount of parent interrupts
+- interrupt-controller: identifies the node as an interrupt controller
+- #interrupt-cells: specifies the number of cells needed to encode an interrupt
+ source, should be 1
+- interrupt-parent: specifies the phandle to the parent interrupt controller
+ this one is cascaded from
+- interrupts: specifies the interrupt line(s) in the interrupt-parent controller
+ node, valid values depend on the type of parent interrupt controller
+- compatible: Should be "brcm,bcm6345-periph-intc".
+- reg: Specifies the base physical address and size of the registers.
+ Multiple register addresses may be specified, and must match the amount of
+ parent interrupts.
+- interrupt-controller: Identifies the node as an interrupt controller.
+- #interrupt-cells: Specifies the number of cells needed to encode an interrupt
+ source, should be 1.
+- interrupt-parent: Specifies the phandle to the parent interrupt controller
+ this one is cascaded from.
+- interrupts: Specifies the interrupt line(s) in the interrupt-parent controller
+ node, valid values depend on the type of parent interrupt controller.
+ Multiple lines are used to route interrupts to different cpus, with the first
+ assumed to be for the boot CPU.
+
+Example:
+
+periph_intc: interrupt-controller@f0406800 {
+ compatible = "brcm,bcm6345-l2-intc";
+ interrupt-parent = <&mips_intc>;
+ #interrupt-cells = <1>;
+ reg = <0x10000020 0x10> <0x10000030 0x10>;
+ compatible = "brcm,bcm6345-periph-intc";
+ reg = <0x10000020 0x10>, <0x10000030 0x10>;
+
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+ interrupt-parent = <&cpu_intc>;
+ interrupts = <2>, <3>;
+};

+Required properties:
+
+- compatible: should be "brcm,bcm6345-l2-intc" or "brcm,bcm6345-l2-intc"
+- reg: specifies the base physical addresses 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, should be 2
+- interrupt-parent: specifies the phandle to the parent interrupt controller
+ this one is cascaded from
+- interrupts: specifies the interrupt line(s) in the interrupt-parent controller
+ node, valid values depend on the type of parent interrupt controller
+- compatible: Should be "brcm,bcm6345-l2-intc".
+- reg: Specifies the base physical addresses 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, Should be 2.
+- interrupt-parent: Specifies the phandle to the parent interrupt controller
+ this one is cascaded from.
+- interrupts: Specifies the interrupt line(s) in the interrupt-parent controller
+ node, valid values depend on the type of parent interrupt controller.
+
+Optional properties:
+
+- brcm,field-width: Size of each field (mask, clear, sense, ...) in bits in the
+ register. Defaults to 4.

+Broadcom BCM6345 Level 1 periphery interrupt controller
+
+This block is a interrupt controller that is typically connected directly
+to one of the HW INT lines on each CPU. Every BCM63XX xDSL chip since
+BCM6345 has contained this hardware.
+
+Key elements of the hardware design include:
+
+- 32, 64, or 128 incoming level IRQ lines
+
+- All onchip peripherals are wired directly to an L2 input
+
+- A separate instance of the register set for each CPU, allowing individual
+ peripheral IRQs to be routed to any CPU
+
+- No atomic mask/unmask operations
+
+- No polarity/level/edge settings
+
+- No FIFO or priority encoder logic; software is expected to read all
+ 1-4 status words to determine which IRQs are pending
+
+Required properties:
+
+- compatible: should be "brcm,bcm6345-l2-intc"
+- reg: specifies the base physical address and size of the registers;
+ multiple regs may be specified, and must match the amount of parent interrupts
+- interrupt-controller: identifies the node as an interrupt controller
+- #interrupt-cells: specifies the number of cells needed to encode an interrupt
+ source, should be 1
+- interrupt-parent: specifies the phandle to the parent interrupt controller
+ this one is cascaded from
+- interrupts: specifies the interrupt line(s) in the interrupt-parent controller
+ node, valid values depend on the type of parent interrupt controller
+- compatible: Should be "brcm,bcm6345-periph-intc".
+- reg: Specifies the base physical address and size of the registers.
+ Multiple register addresses may be specified, and must match the amount of
+ parent interrupts.
+- interrupt-controller: Identifies the node as an interrupt controller.
+- #interrupt-cells: Specifies the number of cells needed to encode an interrupt
+ source, should be 1.
+- interrupt-parent: Specifies the phandle to the parent interrupt controller
+ this one is cascaded from.
+- interrupts: Specifies the interrupt line(s) in the interrupt-parent controller
+ node, valid values depend on the type of parent interrupt controller.
+ Multiple lines are used to route interrupts to different cpus, with the first
+ assumed to be for the boot CPU.
+
+Example:
+
+periph_intc: interrupt-controller@f0406800 {
+ compatible = "brcm,bcm6345-l2-intc";
+ interrupt-parent = <&mips_intc>;
+ #interrupt-cells = <1>;
+ reg = <0x10000020 0x10> <0x10000030 0x10>;
+ compatible = "brcm,bcm6345-periph-intc";
+ reg = <0x10000020 0x10>, <0x10000030 0x10>;
+
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+ interrupt-parent = <&cpu_intc>;
+ interrupts = <2>, <3>;
+};

+Broadcom BCM6345-style external interrupt controller

+Required properties:
+
+- compatible: should be "brcm,bcm6345-l2-intc" or "brcm,bcm6345-l2-intc"
+- reg: specifies the base physical addresses 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, should be 2
+- interrupt-parent: specifies the phandle to the parent interrupt controller
+ this one is cascaded from
+- interrupts: specifies the interrupt line(s) in the interrupt-parent controller
+ node, valid values depend on the type of parent interrupt controller
+- compatible: Should be "brcm,bcm6345-l2-intc".
+- reg: Specifies the base physical addresses 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, Should be 2.
+- interrupt-parent: Specifies the phandle to the parent interrupt controller
+ this one is cascaded from.
+- interrupts: Specifies the interrupt line(s) in the interrupt-parent controller
+ node, valid values depend on the type of parent interrupt controller.
+
+Optional properties:
+
+- brcm,field-width: Size of each field (mask, clear, sense, ...) in bits in the
+ register. Defaults to 4.
