From: Sean Wang <sean.wang@mediatek.com> There are 2 versions of the SoC. MT7623N is almost identical to MT7623A but has some additional multimedia features. The reference boards are available as NAND or MMC and might have a different ethernet setup. In order to reduce the duplication of devicetree code we add an intermediate dtsi file for these reference boards. Additionally Mediatek pointed out, that the EVB is yet another board and the board in question is infact the RFB. Take this into account while renaming the files.You are breaking compatibility with existing DTs. Just document which flavor you want "mediatek,mt7623" to refer to and add the new one. Or just add 2 new strings but keep the old one.
Hi Rob, really appreciate your patient guidance. I prefer to using the way one you suggest: the old one is kept and refers to mt7623n SoC and new one will be added for mt7623a Soc. Sean
