      1Broadcom BCM6345-style Level 1 interrupt controller
      2
      3This block is a first level interrupt controller that is typically connected
      4directly to one of the HW INT lines on each CPU.
      5
      6Key elements of the hardware design include:
      7
      8- 32, 64 or 128 incoming level IRQ lines
      9
     10- Most onchip peripherals are wired directly to an L1 input
     11
     12- A separate instance of the register set for each CPU, allowing individual
     13  peripheral IRQs to be routed to any CPU
     14
     15- Contains one or more enable/status word pairs per CPU
     16
     17- No atomic set/clear operations
     18
     19- No polarity/level/edge settings
     20
     21- No FIFO or priority encoder logic; software is expected to read all
     22  2-4 status words to determine which IRQs are pending
     23
     24Required properties:
     25
     26- compatible: should be "brcm,bcm<soc>-l1-intc", "brcm,bcm6345-l1-intc"
     27- reg: specifies the base physical address and size of the registers;
     28  the number of supported IRQs is inferred from the size argument
     29- interrupt-controller: identifies the node as an interrupt controller
     30- #interrupt-cells: specifies the number of cells needed to encode an interrupt
     31  source, should be 1.
     32- interrupts: specifies the interrupt line(s) in the interrupt-parent controller
     33  node; valid values depend on the type of parent interrupt controller
     34
     35If multiple reg ranges and interrupt-parent entries are present on an SMP
     36system, the driver will allow IRQ SMP affinity to be set up through the
     37/proc/irq/ interface.  In the simplest possible configuration, only one
     38reg range and one interrupt-parent is needed.
     39
     40The driver operates in native CPU endian by default, there is no support for
     41specifying an alternative endianness.
     42
     43Example:
     44
     45periph_intc: interrupt-controller@10000000 {
     46        compatible = "brcm,bcm63168-l1-intc", "brcm,bcm6345-l1-intc";
     47        reg = <0x10000020 0x20>,
     48              <0x10000040 0x20>;
     49
     50        interrupt-controller;
     51        #interrupt-cells = <1>;
     52
     53        interrupt-parent = <&cpu_intc>;
     54        interrupts = <2>, <3>;
     55};
