We've been over this already, and I'll tell you again that you're
getting this wrong.

No platform is more entitled to get merged than another one. I do care
about the Allwinner SoCs, and I care just as much about the broader
Linux support for all the other SoCs, be it from nvidia, samsung or
whatever vendor you can come up with.

But you can't hide the fact that the bcm2835 still has a very limited
clock support, and I really don't know about its clock tree, but I
guess that if the times come when they add a more complete clock
support, they will face the same issue.

If the driver would have been developped initially to create a
framebuffer on the Allwinner SoCs, at a time when we didn't have any
clock support too, calling it only usable on sunxi wouldn't have
shocked me tbh.
