## Incorrect naming
MT7620, MT7621, MT7628, and MT7688 SoCs are incorrectly called Ralink,
introduce new ralink->mediatek compatible strings to address it.
So this part was addressed by Rob - we don't do it, because it does not
matter. Ralink is now Mediatek, thus there is no conflict and no issues
with different vendor used.
I think Rob was rather addressing that updating compatible strings based
on acquisition or marketing whims is not permitted. This condition does
not apply here as these SoCs were never Ralink.
I understand your point that Ralink is now MediaTek but still, calling
these SoCs Ralink would be a bit misleading, don't you think?
Misleading yes, but also does not matter. At least matter not enough to
justify ABI break, so you would need to deprecate old ones and keep
everything backwards compatible. You still would affect 3rd party users
of DTS, though...
I intend to do just that. Introduce new mediatek strings, keep the old
ones so it's backwards compatible, therefore don't break the ABI.
Instead of deprecating old strings, I intend to introduce the checks I
mentioned, on the schema, so the pin muxing bindings only apply if the
DT has got a string that won't match multiple schemas. This way it
shouldn't affect 3rd party DTs.
I meant, 3rd party users of DTS. You will replace the compatible in the
DTS, right? So the DTS exported and used in all other projects, OS,
firmwares, bootloaders, out of tree kernel forks will stop working.
I plan to change it on the DTs for MediaTek SoCs, yes. Is this a
problem? From what I can tell, what must be ensured is that old DTs must
work with newer kernels, not new DTs on older kernels.
