Any feedback from firmware/meson maintainers already ? Wouldn't this be better
as its own patchset and documented as dependency ? Both ways work, but
understand that I cannot take your patches until these are in Linus tree (won't
build). This comments applies to patch 1/2, please coordinate and let us know
what is the plan.
