Hi Stefan,

This patch adds the Ethernet over UART driver for the Qualcomm QCA7000 HomePlug GreenPHY.

this seems to be another candidate for having a proper UART or serial bus. Instead of adding one line discipline after another, I think we need to get quickly to having an enumerable bus here. Regards Marcel
