From: Arınç ÜNAL <redacted>

Add the ralink,rt2880-pinmux compatible string. It had been removed from
the driver which broke the ABI.

Add the mediatek compatible strings. Change the compatible string on the
examples with the mediatek compatible strings.

We don't update compatible strings based on acquistions nor marketing
whims. If you want to use 'mediatek' for new things, then fine.

Understood. Only the SoCs with rtXXXX were rebranded, the mtXXXX SoCs share
the same architecture from Ralink, so they were incorrectly called Ralink
SoCs.

I can remove the new strings from Ralink SoCs and add them only for MediaTek
SoCs. Or you could make an exception for this one, regarding the situation.
Whatever you think is best.

I'm not in a position to make an exception as I know little about this 
platform. Carrying both strings is a NAK. Either you (and everyone using 
these platforms) care about the ABI and are stuck with the "wrong" 
string. In the end, they are just unique identifiers. Or you don't care 
and break the ABI and rename everything. If you do that, do just that in 
your patches and make it crystal clear in the commit msg that is your 
intention and why that is okay.
