++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:
 +

-+	compatible = "brcm,bcm6345-l2-intc";
-+	interrupt-parent = <&mips_intc>;

 +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.

++Optional properties:
++
++- brcm,field-width: Size of each field (mask, clear, sense, ...) in bits in the

++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>;

-+- reg: specifies the base physical addresses and size of the registers.
-+- interrupt-controller: identifies the node as an interrupt controller
