I would be fine with one patch introducing the defines and then
one big patch switching everybody and their dog over to using
these definitions.

I usually keep to a patch being "one technical step" and it is
clearly (IMO) one step to introduce the defines and one step
to make use of it in all legacy drivers.

It's late in the kernel cycle but this particular part (the defines
and switching over old driver to use it) I'd be happy
to merge for v5.5.

Yours,
