-* Freescale Layerscape external IRQs
-
-Some Layerscape SOCs (LS1021A, LS1043A, LS1046A
-LS1088A, LS208xA, LX216xA) support inverting
-the polarity of certain external interrupt lines.
-
-The device node must be a child of the node representing the
-Supplemental Configuration Unit (SCFG).
-
-Required properties:
-- compatible: should be "fsl,<soc-name>-extirq", e.g. "fsl,ls1021a-extirq".
- "fsl,ls1043a-extirq": for LS1043A, LS1046A.
- "fsl,ls1088a-extirq": for LS1088A, LS208xA, LX216xA.
-- #interrupt-cells: Must be 2. The first element is the index of the
- external interrupt line. The second element is the trigger type.
-- #address-cells: Must be 0.
-- interrupt-controller: Identifies the node as an interrupt controller
-- reg: Specifies the Interrupt Polarity Control Register (INTPCR) in
- the SCFG or the External Interrupt Control Register (IRQCR) in
- the ISC.
-- interrupt-map: Specifies the mapping from external interrupts to GIC
- interrupts.
-- interrupt-map-mask: Must be <0xffffffff 0>.
-
-Example:
- scfg: scfg@1570000 {
- compatible = "fsl,ls1021a-scfg", "syscon";
- reg = <0x0 0x1570000 0x0 0x10000>;
- big-endian;
- #address-cells = <1>;
- #size-cells = <1>;
- ranges = <0x0 0x0 0x1570000 0x10000>;
