Subject: net: dwc_eth_qos: Implement bind() for PCI devices
X-Git-Url: http://git.dujemihanovic.xyz/%7B%7B%20%24style.RelPermalink%20%7D%7D?a=commitdiff_plain;h=2689b14ef3d4a4702330a03431f09847ef8e2090;p=u-boot.git

net: dwc_eth_qos: Implement bind() for PCI devices

PCI devices do not necessarily use a device tree. Implement a bind()
function to assign unique device names in that case.
