From 48d4988f2b3b93a6f17c0d1d5e6d932664bc0c74 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sat, 26 Nov 2016 00:17:22 +0100 Subject: [PATCH 08/39] ARM64: dts: meson-gxm: add GXM specific USB host configuration The USB configuration on GXM is slightly different than on GXL. The dwc3 controller's internal hub has three USB2 ports (instead of 2 on GXL) along with a dedicated USB2 PHY for this port. However, it seems that there are no pins on GXM which would allow connecting the third port to a physical USB port.
