From 65f3d449f4386c4aced2fb7252905240b4f45cd3 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Thu, 17 Sep 2020 08:59:47 +0200 Subject: usb: dwc-meson-g12a: Add support for USB on AXG SoCs The Amlogic AXG is close to the GXL Glue but with a single OTG PHY. It needs the same init sequence as GXL & GXM, but it seems it doesn't need the host disconnect bit.
