I believe there aren't direct dependencies between the patches. So, the
MFD patches can be applied to the MFD tree and the DT patch applied to
the Tegra tree. I'm simply waiting for the MFD patches to be applied
before applying the DT patch so that I know the DT binding definition is
fully accepted before applying a patch that uses it.
