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.

National Instruments Ettus Research USRP E3x0 button driver
This module is part of the NI Ettus Research USRP E3x0 SDR.
This module provides a simple power button event via two interrupts.
Required properties:
- compatible: should be one of the following
- "ettus,e3x0-button": For devices such as the NI Ettus Research USRP E3x0
- interrupts: should be one of the following
- <0 30 1>, <0 31 1>: For devices such as the NI Ettus Research USRP E3x0
- interrupt-names: should be one of the following
- "press", "release": For devices such as the NI Ettus Research USRP E3x0
Note: Interrupt numbers might vary depending on the FPGA configuration.
Example:
button {
compatible = "ettus,e3x0-button";
interrupt-parent = <&intc>;
interrupts = <0 30 1>, <0 31 1>;
interrupt-names = "press", "release";
}
