It handles necessary Samsung Exynos-specific resources (regulators, clocks), but does not have its own MMIO address space. However neither simple-bus bindings nor dtc W=1 accept device nodes in soc@ node which do not have unit address. Signed-off-by: Krzysztof Kozlowski --- Changes since v1: 1. Use ranges with values and drop reg from usb-wrapper node. 2. Keep "usb" as wrapper's node name.
