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.

MaJun	d0e286415d	irqchip/mbigen: Adjust DT bindings to handle multiple devices in a module ... A mbigen hardware module can contain more than one device node. These device nodes contain the same register definition. mbigen_dev1:intc_dev1 { ... reg = <0x0 0xc0080000 0x0 0x10000>; ... }; mbigen_dev2:intc_dev2 { ... reg = <0x0 0xc0080000 0x0 0x10000>; ... }; In this case both devices try to request the same resource resulting in a resource conflict. To address this problem the devices need to be subnodes of the mbigen hardware module, which then contains the unique register space.
