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.

* Texas Instruments OMAP4+ Digital Microphone Module
Required properties:
- compatible: "ti,omap4-dmic"
- reg: Register location and size as an array:
<MPU access base address, size>,
<L3 interconnect address, size>;
- interrupts: Interrupt number for DMIC
- ti,hwmods: Name of the hwmod associated with OMAP dmic IP
Example:
dmic: dmic@4012e000 {
compatible = "ti,omap4-dmic";
reg = <0x4012e000 0x7f>, /* MPU private access */
<0x4902e000 0x7f>; /* L3 Interconnect */
interrupts = <0 114 0x4>;
interrupt-parent = <&gic>;
ti,hwmods = "dmic";
};
