Subject: ar71xx: fix double registration of usb host mode devices, add usb client support... 
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fa22714181;p=openwrt%2Fstaging%2Fneocturne.git

ar71xx: fix double registration of usb host mode devices, add usb client support for qca955x

Only register the chipidea usb device if the strapping option indicates
device mode. If not, use the regular ehci platform driver.

Add qca955x device mode support, tested on 8devices Rambutan.
