Can you make sure your changelog texts explain why you do this?
Are they fundamentally different from the devices you had
claimed to be compatible with that need a different driver,
or are there drivers in the field that bind to the wrong
string first?

Yes, sorry I wasn't clear.

UART and SDHC had drivers added which are better fit.
The GPT binds to imx6dl which is also the same as imx6sl.

I don't understand?

Thanks,

Where are those drivers added? Looking at linux-6.1-rc2
and linux-next, I still see them use the same drivers as
the original ones, and listing both strings would be the
preferred method.

I mean if you had run into the case where you have
a driver that misbehaves when the fallback string is
present in addition to the most specific one.

I applied patches 1-6 to the pinctrl tree, this one seems independent
and possibly should not even be applied as I understand it.

Yours,
