Hi Michael,
Finally I got all the acks for these patches. The following two patches in v2
were merged into next now.
213dce3c17a6 (tty: kconfig: remove the superfluous dependency on
PPC_OF)
f4e074f20cad (mmc: kconfig: replace PPC_OF with PPC)
So we may have dependency issue if
The OF functionality has moved to a common place and be used by many
archs. So we don't need to include the ppc arch specific header files
and depend on PPC_OF option any more. This is a preparation for
killing PPC_OF.

The PPC_OF is a ppc specific option which is used to mean that the
firmware device tree access functions are available. Since all the
ppc platforms have a device tree, it is aways set to 'y' for ppc.
So it makes no sense to keep a such option in the current kernel.
Replace it with PPC.

No released machines ever supported that, and even in the lab it was
