From d49850110434e25b3128a4f2f083812a111bf457 Mon Sep 17 00:00:00 2001 From: Amelie Delaunay Date: Fri, 24 Jan 2020 09:41:30 +0100 Subject: [PATCH] dt-bindings: usb: dwc2: add support for STM32MP15 SoCs USB OTG HS and FS Add the specific compatible string for the DWC2 IP found in the STM32MP15 SoCs. STM32MP15 SoCs uses sensing comparators to detect Vbus valid levels and ID pin state. usb33d-supply described the regulator supplying Vbus and ID sensing comparators.
