[v3,08/15] dt-bindings: interrupt-controller: Merge BCM3380 with BCM7120

Commit Message

The two bindings are very similar and should be covered by the same
document, do that so we can get rid of an additional binding file.

-Broadcom BCM3380-style Level 1 / Level 2 interrupt controller
-
-This interrupt controller shows up in various forms on many BCM338x/BCM63xx
-chipsets.  It has the following properties:
-
-- outputs a single interrupt signal to its interrupt controller parent
-
-- contains one or more enable/status word pairs, which often appear at
-  different offsets in different blocks
-
-- no atomic set/clear operations
-
-Required properties:
-
-- compatible: should be "brcm,bcm3380-l2-intc"
-- reg: specifies one or more enable/status pairs, in the following format:
-  <enable_reg 0x4 status_reg 0x4>...
-- 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 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 L2 controller can be used as a
-  wakeup source for system suspend/resume.

-Example:
-
-irq0_intc: interrupt-controller@10000020 {

-	interrupt-controller;
-	#interrupt-cells = <1>;
-	interrupt-parent = <&cpu_intc>;
