It's an optional feature of the controller. This series implements the feature and enables it as a workaround for a particular version of the controller. This binding enables and configures the feature with an interval value which is specified as a number of 250 ns increments. I'll update the binding text to something like this: - snps,imod-interval: the interrupt moderation interval, specified in 250 ns increments from 1 to 0xffff.
