Binding description is missing interrupt property. Remeber that the DT should 
describe the HW, so we need to update the binding description.
I just wonder what the IRQ signals, as it is not used by the driver. Definitely 
a good candidate to make the commit message more sound. So please add it there.

Thanks!
