No changes since v1.
Note this patch still needs another patch from Wolfram to work.
I send out it in this series as
[PATCH 3/3] arm: mxs: disable clock-gates when setting saif-clocks
As discussed with Wolfram, that patch may still have some later work
to do. However, we just send out it for testers to work first.
