If so, is the API > that I suggested going to work for controlling those clocks, too? Well, I don't really know that hardware in detail. I just browsed the code, e.g: http://git.kernel.org/?p=linux/kernel/git/davem/net-next-2.6.git;a=commit;h=38c845c76 http://marc.info/?l=linux-netdev&m=126389931509102&w=2 But I believe that your interface is generic enough to support that hardware as well. Would make sense to put the relevant people on CC and also "ptpd@lists.infradead.org." Wolfgang.
