-Broadcom BCM7038-style Level 1 interrupt controller
-
-This block is a first level interrupt controller that is typically connected
-directly to one of the HW INT lines on each CPU. Every BCM7xxx set-top chip
-since BCM7038 has contained this hardware.
-
-Key elements of the hardware design include:
-
-- 64, 96, 128, or 160 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
-
-- Atomic mask/unmask operations
-
-- No polarity/level/edge settings
-
-- No FIFO or priority encoder logic; software is expected to read all
- 2-5 status words to determine which IRQs are pending
-
-Required properties:
-
-- compatible: should be "brcm,bcm7038-l1-intc"
-- reg: specifies the base physical address and size of the registers;
- the number of supported IRQs is inferred from the size argument
-- 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.
-- 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,irq-can-wake: If present, this means the L1 controller can be used as a
- wakeup source for system suspend/resume.
-
-Optional properties:
-
-- brcm,int-fwd-mask: if present, a bit mask to indicate which interrupts
- have already been configured by the firmware and should be left unmanaged.
- This should have one 32-bit word per status/set/clear/mask group.
-
-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.
-
-Example:
-
-periph_intc: periph_intc@1041a400 {
- compatible = "brcm,bcm7038-l1-intc";
- reg = <0x1041a400 0x30 0x1041a600 0x30>;
-
- interrupt-controller;
- #interrupt-cells = <1>;
-
- interrupt-parent = <&cpu_intc>;
- interrupts = <2>, <3>;
-};
