[RFT PATCH v3 2/4] ARM: dts: exynos: add unit address to DWC3 node wrapper in Exynos54xx

From: Krzysztof Kozlowski
Date: Fri Jan 27 2023 - 16:28:30 EST


Neither simple-bus bindings nor dtc W=1 accept device nodes in soc@ node
which do not have unit address. Therefore usethe address space
of child device (actual DWC3 Controller) as the wrapper's address to
fix:

exynos5422-odroidhc1.dtb: soc: usb3-0: {'compatible': ['samsung,exynos5250-dwusb3'],
... } should not be valid under {'type': 'object'}

exynos54xx.dtsi:145.21-159.5: Warning (simple_bus_reg): /soc/usb3-0: missing or empty reg/ranges property

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>

Changes since v1:
1. Use ranges with values and drop reg from usb-wrapper node.
2. Keep "usb" as wrapper's node name.
