So, you didn't run that code through checkpatch and you rewrite the
whole thing entirely without even testing it... Awesome.

For the record, I'm still very much opposed to such a merge.

The first fixes are very welcome though, can and should go in.

Aside from the DMA part this is not a rewrite.

And I did run the code through checkpatch. It still gives some
warnings about BUG_ON and overly long lines, sure. II don't think
those are that serious or that fixing them would improve the code.

Thanks

What is the reason against the merge? I did not find the original discussion.

I tried to rename everything in the drivers from sun4i and sun6i to
sunxi to look at a clean diff and found about 5 differences 2 of which
look like a bug.

Thanks
