Yes. All three (ipq6018, ipq8074, ipq9574) have this range.

Since all three have this range will this commit message be ok?

	Append the MHI register range to ipq6018, ipq8074-gen3 & ipq9574. This
	is an optional range used by the dwc controller driver to print debug
	stats via the debugfs file 'link_transition_count'.

Additionally, should I update ipq6018.dtsi and ipq8074.dtsi also and include in
this patchset?

Thanks
Varada
