Subject[PATCH 23/32] dt-bindings: phy-rockchip-inno-usb2: add assign clock property in usb2-phy node
Date
From: Meng Dongyang <daniel.meng@rock-chips.com>

On some platform such as RK3328, the 480m clock may need to assign
clock parent in dts in stead of clock driver. So this patch add
property of assigned-clocks and assigned-clock-parents to assign
parent for 480m clock.
