[PATCH 04/12] ARM: dts: exynos: add USB DWC3 supplies to Chromebook Snow

From: Krzysztof Kozlowski
Date: Sun Jan 23 2022 - 06:17:18 EST


Add required voltage regulators for USB DWC3 block on Exynos5250
Chromebook Snow board. Due to lack of board schematics, use same
regulators as on Arndale board.
