Subject: [PATCH v2 0/5] usb: dwc-meson-g12a: Add support for USB on S400 board

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.

The Glue driver reuses the already implemented GXL & GXM work.

The USB2 PHY driver needs a slight tweak to keep the OTG detection working.

Changes since v1 at [1]:
- s/close from/close to/g
- collected review tags
- added small comment about phy management in patch 3
- removed status = "okay" in patch 4
- removed invalid phy-supply of phy1 in patch 5
