Subject: dts: qcs404-evb: Add USB controller and PHY nodes
X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=0c1eab6f759c6abe809bc68c44192924b1d2522a;p=u-boot.git

dts: qcs404-evb: Add USB controller and PHY nodes

QCS404 SoC provides support for two USB controllers: one USB3 and the
other one being USB2. The USB3 controller supports further 2 PHY: one high
speed PHY and the other super speed PHY. The USB2 controller supports a
single high speed PHY. So add corresponding DT nodes.
