From 4043114504cc05d0a7ca2a061838699b500599cd Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sun, 23 Jan 2022 12:16:42 +0100 Subject: [PATCH] ARM: dts: exynos: add fake USB DWC3 supplies to SMDK5410 Add dummy/fake voltage regulators for USB DWC3 block on Exynos5410 SMDK5410 board. These regulators are required by dtschema, however the SMDK5410 board does not define the PMIC providing regulators. Use dummy fixed-regulators just to satisfy the dtschema checks.
