[PATCH 11/12] m68k/atari: USB - add platform devices for EtherNAT/NetUSBee ISP1160 HCD

Michael Schmitz
2013-04-06T00:27:28Z

Add platform devices used by the isp116x-hcd driver for EtherNAT and
NetUSBee. Note that the NetUSBee also contains a RTL8019 Ethernet chip,
so its platform device is used to cover the EtherNEC case, too.
