Hi Jacek, I find myself needing these bindings as well, so I'm definitely interested by your patches.

Plus, I guess that it's assuming that you can only use INT2 when you already use INT1? > + - irq-map : irq sub-node defining interrupt map > + (all properties listed below are required): > + - #interrupt-cells : should be 1 > + - #address-cells : should be 0 > + - #size-cells : should be 0 > + - interrupt-map : table of entries consisting of three child elements: > + - unit_interrupt_specifier - 0 : INT1, 1 : INT2 > + - interrupt parent phandle > + - parent unit interrupt specifier consisiting of two elements: > + - index of the interrupt within the controller > + - flags : should be 0 I don't really get why it's needed. Isn't that redundant with the interrupt parent and the interrupt number already defined by interrupt-parent and interrupts in the top node?
