The kernelci.org bot reported sunxi a20 boot failures[1][2] in
next-20150720 and next-20150721. I have bisected[3] these failures to
this commit. However, I have not investigated any further but
reverting this commit on top of next-20150721 gets the boards booting
again.

Cheers,

Tyler

I've tested the patch below on top of next-20150721 and can confirm it
fixes the sunxi a20 issues I've reported.

Thanks both. I've squashed this in and pushed it out to clk-next.
