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.

Zynq Watchdog Device Tree Bindings
-------------------------------------------
Required properties:
- compatible : Should be "cdns,wdt-r1p2".
- clocks : This is pclk (APB clock).
- interrupts : This is wd_irq - watchdog timeout interrupt.
Optional properties
- reset-on-timeout : If this property exists, then a reset is done
when watchdog times out.
- timeout-sec : Watchdog timeout value (in seconds).
Example:
watchdog@f8005000 {
compatible = "cdns,wdt-r1p2";
clocks = <&clkc 45>;
interrupt-parent = <&intc>;
interrupts = <0 9 1>;
reg = <0xf8005000 0x1000>;
reset-on-timeout;
timeout-sec = <10>;
};
