Sorry for the bad description. I will correct it in the next version.

For the second part of the question, this change was done as a step to
resolve having a new compatible while having practically the same IP
pointed out in the v3 of the series [1]. It is kind of looping back to
the initial idea now. Even if this is added as a driver data, it
overrides the expectation from the comment in [1]. Please suggest. I
also read Rob's concerns on having a device tree property for number of
irqs.
