[PATCH 0/8] ARM: mach-meson: update & rework USB for GXL, GXM & AXG

[Neil Armstrong]

This serie follows the recent work under Linux to rework and update support of
the USB complex in the Amlogic GXL, GXM & AXG SoCs.

This rework follows the clean implementation for the G12A & following SoCs to support
Host, Device & OTG functionnality.

The GXL, GXM & AXG USB complex is architectured in the same was as the G12A & later USB complex,
thus we can use the same architecture but adapted to the different init & config flow found
in the Amlogic GXL, GXM & AXG SoCs.

With this patchset, USB Host functionnality is retained, working & tested on the Khadas VIM2 (GXM),
Libretech-CC (GXL) & S400 (AXG), with Device mode added and tested by using the UMS gadget.

Neil Armstrong (8):
  ARM: dts: sync amlogic AXG/GXL/GXM DT from Linux 5.8-rc1
  usb: dwc3: add Amlogic GXL & GXL DWC3 Glue
  ARM: mach-meson: use new DWC3 glue for GXL & GXM
  phy: meson-gxl: remove invalid USB3 PHY driver
  phy: meson-gxl-usb: depend on Meson AXG aswell
  arm: meson-axg: add board_usb_init()/cleanup() for USB gadget
  ARM: dts: meson-axg: add USB nodes for S400
  configs: s400: enable USB
