Hm, to me that's confusing. What about:
"mediatek,mt7623-btif": for MediaTek MT7623
"mediatek,mt7622-btif", "mediatek,mt7623-btif": for MediaTek MT7622
If in the future we have more SoCs that support the BTIF, we should add them
like the mt7622 case.
I had v3, but it should have similar logic and also got ack from Rob
I knew all your logic of adding binding document for all MediaTek
devices, even I alway added MediaTek device in dt-bindings as the way
you mentioned here, but I felt this way is fine for this kind of
dedicated document.
The reason i don't add it as usual is the following. 8250.txt is common
and shared among all uart like devices, so i don't want btif device
occupies too much section and bloat the document when every new MediaTek
SoC is introduced.
So instead I refer to existing Nvidia device added in 8250.txt which I
thought its way is simple, elegant and also using pattern I can use to
add btif devices.
Working on my email backlog after vactions I didn't see that this was accepted
by Rob. Sorry for the noise.
