I have to confess I lost track of the multitude of patches touching
the gmac on rk3328 and their long mail threads in terms of which
to pick up and which are considered superseeded.

So I'd really appreciate if you could resend the patches that matter
and provide relevant Tested-by, Reviewed-by, etc tags from involved
people that actually were able to test patches

Thanks
