I don't think this is strictly speaking necessary -- it's mostly going to be implicit (it is in the dtsi below). As this is a standard property, you don't need to document it here. > +- interrupts : the interrupt number for the SHAM module. Sorry, I missed this last time, but this should be interrupt-specifier rather than interrupt number. Otherwise, this looks good to me.
