The Cadence QSPI IP is usually described using two compatibles, and the second is cdns,qspi-nor. The way that has been historically used to describe RZ/N1D IPs, however, is to use 3 compatibles. I wanted to "align" with this, ie. declaring 3 strings instead of 2. I will change the commit log to: This SoC is identified in the bindings with its other name: r9a06g032. It is part of the RZ/N1 family, which contains a "D" and a "S" variant. IPs in this SoC are typically described using 3 compatibles (the SoC specific compatible, the family compatible, and the original Cadence IP compatible), follow this convention. I hope this is clearer. Thanks, Miqu=C3=A8l
