Dear Russell,
The "[PATCH v2] ARM: Add common files of platform definition and cpu."
patch is a old one.
I have a updated version below.
I have added the 'ts' driver name changing to this the updated patch.
In fact, I did not re-send it to maillist, but to submit it to your
patch system directly.
This updated patch has been sent to your patch system.
