Rob Herring 791d3ef2e1 dt-bindings: remove 'interrupt-parent' from bindings
'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

Sigma Designs SMP86xx/SMP87xx secondary interrupt controller
Required properties:
- compatible: should be "sigma,smp8642-intc"
- reg: physical address of MMIO region
- ranges: address space mapping of child nodes
- interrupt-controller: boolean
- #address-cells: should be <1>
- #size-cells: should be <1>
One child node per control block with properties:
- reg: address of registers for this control block
- interrupt-controller: boolean
- #interrupt-cells: should be <2>, interrupt index and flags per interrupts.txt
- interrupts: interrupt spec of primary interrupt controller
Example:
interrupt-controller@6e000 {
compatible = "sigma,smp8642-intc";
reg = <0x6e000 0x400>;
ranges = <0x0 0x6e000 0x400>;
interrupt-parent = <&gic>;
interrupt-controller;
#address-cells = <1>;
#size-cells = <1>;
irq0: interrupt-controller@0 {
reg = <0x000 0x100>;
interrupt-controller;
#interrupt-cells = <2>;
interrupts = <GIC_SPI 2 IRQ_TYPE_LEVEL_HIGH>;
};
irq1: interrupt-controller@100 {
reg = <0x100 0x100>;
interrupt-controller;
#interrupt-cells = <2>;
interrupts = <GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>;
};
irq2: interrupt-controller@300 {
reg = <0x300 0x100>;
interrupt-controller;
#interrupt-cells = <2>;
interrupts = <GIC_SPI 4 IRQ_TYPE_LEVEL_HIGH>;
};
};
