Hi Jerome

Some maintainers like to have code in their directory structure. It
would be good to check that the clock maintainer in happy with clock
code under the network driver subtree. Also, the clock maintainer
should also review this code. So please at least Cc: the clock
maintainer and clock list on the next submission, as well as netdev. I
personally don't know the clock code well enough to review such code.
