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.

Broadcom STB wake-up Timer
The Broadcom STB wake-up timer provides a 27Mhz resolution timer, with the
ability to wake up the system from low-power suspend/standby modes.
Required properties:
- compatible : should contain "brcm,brcmstb-waketimer"
- reg : the register start and length for the WKTMR block
- interrupts : The TIMER interrupt
- clocks : The phandle to the UPG fixed clock (27Mhz domain)
Example:
waketimer@f0411580 {
compatible = "brcm,brcmstb-waketimer";
reg = <0xf0411580 0x14>;
interrupts = <0x3>;
interrupt-parent = <&aon_pm_l2_intc>;
clocks = <&upg_fixed>;
};
