This v6 overall looks good to me!
Reviewed-by: Linus Walleij <linus.walleij@xxxxxxxxxx>
Can the patch be merged on its own?

Didn't notice this before. But if Andy is OK with it, I'm
OK with it, I guess there is a reason? Perhaps it warrants
a comment explaining why you do this?
Valid reasons:
- You are using Intel-specific HW features also found in this
FPGA
Invalid reasons:
- Using nifty macros or helpers, then either make them generic
or (if they are small) duplicate them.
If it was that thing I asked Andy to keep locally because I didn't
agree with its generic usefulness, maybe I should be told to
reconsider.
Yours,
