+description: >
+ This block is a first level interrupt controller that is typically connected
+ directly to one of the HW INT lines on each CPU.
+
+ Key elements of the hardware design include:
+
+ - 32, 64 or 128 incoming level IRQ lines
+
+ - Most onchip peripherals are wired directly to an L1 input
+
+ - A separate instance of the register set for each CPU, allowing individual
+ peripheral IRQs to be routed to any CPU
+
+ - Contains one or more enable/status word pairs per CPU
+
+ - No atomic set/clear operations
+
+ - No polarity/level/edge settings
+
+ - No FIFO or priority encoder logic; software is expected to read all
+ 2-4 status words to determine which IRQs are pending
+
+ If multiple reg ranges and interrupt-parent entries are present on an SMP
+ system, the driver will allow IRQ SMP affinity to be set up through the
+ /proc/irq/ interface. In the simplest possible configuration, only one
+ reg range and one interrupt-parent is needed.
+
+ The driver operates in native CPU endian by default, there is no support for
+ specifying an alternative endianness.
