From 31c33503fdb3965d6aaf0db4a8c42e7d8cef1dff Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sun, 23 Jan 2022 12:16:33 +0100 Subject: [PATCH] arm64: dts: exynos: add USB DWC3 supplies to Espresso board Add required voltage regulators for USB DWC3 block on Exynos7 Espresso board. Due to lack of schematics of Espresso board, the choice of regulators is approximate. What bindings call VDD10, for Exynos7 should be actually called VDD09 (0.9 V). Use regulators with a matching voltage range based on vendor sources for Meizu Pro 5 M576 handset (also with Exynos7420).
