Acked-by: David Brown <davidb@codeaurora.org> I believe that Stepan Moskovochenko has some extra tests for this code, but given that none of the code itself changes, I wouldn't expect any problems.

This should ease finding similarities with different platforms, with the intention of solving problems once in a generic framework which everyone can use. Compile-tested for MSM8X60.
