Do you have an out-of-tree dts file? If not, I'd prefer that the fix
was for this patch to land instead:
https://lore.kernel.org/r/1583747589-17267-9-git-send-email-sanm@xxxxxxxxxxxxxx
While we can land your patch if someone needs it for supporting an
out-of-tree dts, it gives people supporting future SoCs the idea that
they need to add themselves to this table too. That's now discouraged
unless there's a specific quirk that needs to be handled just for this
SoC.
