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.

TB10x Top Level Interrupt Controller
====================================
The Abilis TB10x SOC contains a custom interrupt controller. It performs
one-to-one mapping of external interrupt sources to CPU interrupts and
provides support for reconfigurable trigger modes.
Required properties
-------------------
- compatible: Should be "abilis,tb10x-ictl"
- reg: specifies physical base address and size of register range.
- interrupt-congroller: Identifies the node as an interrupt controller.
- #interrupt cells: Specifies the number of cells used to encode an interrupt
source connected to this controller. The value shall be 2.
- interrupts: Specifies the list of interrupt lines which are handled by
the interrupt controller in the parent controller's notation. Interrupts
are mapped one-to-one to parent interrupts.
Example
-------
intc: interrupt-controller { /* Parent interrupt controller */
interrupt-controller;
#interrupt-cells = <1>; /* For example below */
/* ... */
};
tb10x_ictl: pic@2000 { /* TB10x interrupt controller */
compatible = "abilis,tb10x-ictl";
reg = <0x2000 0x20>;
interrupt-controller;
#interrupt-cells = <2>;
interrupt-parent = <&intc>;
interrupts = <5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
20 21 22 23 24 25 26 27 28 29 30 31>;
};
