This patchset adds support for USB for the Amlogic Meson GXL SoCs following
the work done for Linux by Martin Blumenstingl at   .
The support consist of :
- A port of dwc3-of-simple from Linux to U-boot
- A change to support more than 2 PHYs in the DWC3 DM driver
- An USB2 PHY Driver and an USB3 PHY Driver
The DWC3 Controller has up to 4 PHYs connected :
- 2 USB2 PHYs and an USB3 PHY for GXL SoCs
- 3 USB2 PHYs and an USB3 PHY for the GXM SoC Variant
This is enabled by the "usb: host: dwc3: Add support for multiple PHYs" patch.
This patch is based on the "xhci-dwc3: Couple of fixes for USB3 support"
serie from Vignesh R, on the u-boot-usb tree.
The DWC3 Controller glue is generic enough to use the dwc3-of-simple from Linux
and can be easily ported to U-Boot as a Simple-Bus with Glue-Specific clocks
and Reset lines setup.
The USB PHY driver supports the standard generic PHY interface and supports
the power-on/off calls and set the Host mode by default.
They are based on the excellent work from Martin Blumenstingl merged in linux.
