[RFC v1 0/7] Meson GXL/GXM USB host mode support

[Martin Blumenstingl]

this is for testing USB host mode support on Meson GXL and GXM.
there are four dependencies to get this working:
1. "improvements and fixes for the phy-meson-gxl-usb2 driver" from [0]
   (this is already queued for v4.17 and part of linux-next)
2. "DWC3 support for Amlogic Meson AXG and GXL SoCs from" [1] (this is
   also queued for v4.17 and part of linux-next)
3. "initialize (multiple) PHYs for a HCD" from [3] (this is also queued
   for v4.17 and part of linux-next)
4. "Meson GXL USB3 PHY driver" from [3] (this is NOT queued for v4.17
   yet and thus also not in linux-next yet)

select boards get USB enabled. I have tested this myself successfully
on:
- Khadas VIM (GXL S905X)
- Le Potato (GXL S905X)
- Khadas VIM2 (GXM S912)
- a board which is similar to P230 (GXL S905D)

I don't remember why I have Nexbox A95X (S905X) support in my tree.
Neil: maybe you can test this on your board (if you still have it)?
