We have two independent patches for performing MMC bus-width testing now:

  https://patchwork.kernel.org/patch/351781/
  https://patchwork.kernel.org/patch/361702/

I'm planning on taking Takashi's since it looks a little cleaner; Philip,
please could you take a look at Takashi's patch and add anything you
think should be present from your own patch as a new incremental patch?

Thanks very much,

- Chris.
